I’ve been very stressed lately and have been doing some window shopping to calm down. I’m interested in gadgets, but a lot of things can just be replaced with apps. I realize a phone won’t replace very large appliances like refrigerators or washing machines so I’m trying to scope my question to portable devices. So what are some portable devices or gadgets that their specialization hasn’t been replaced by smart phone apps? Extra points if they’re super useful and reliable.
Radiation detectors. Such as the Radiacode or the Open Gamma Detector.
Binoculars are quite portable, very useful, and phones don’t do a good job at zooming in like that.
Smart watches integrate with phones but the phones by themselves are not so good at measuring the heart rate and other parameters directly.
Mini projectors. UV flashlights. Tools in general… There is so much actually. What type of gadgets are you looking for?
Samsung S2x Ultra has 10x optical zoom. That’s pretty much a <100€ binocular right there.
My experience with phone zoom has been underwhelming so far, but I would like to check out the Samsung S2x’s 10x zoom when I have the chance!
Still, I really like using binoculars because they transport me next to what I am looking at and do so in very high definition. I do have >100€ binoculars though, colors look very nice through them. I think it will be difficult to replicate via a screen.
Not comparable for viewing purposes, don’t bother. But it’s good for capturing a memory of it.
The light isn’t enough, there’s ai artefacts, lower refresh rate makes it obvious the movements aren’t real time. Not a monocular replacement.
Well the phone is a bit of a “jack of trades master of none”. You pretty much always will have a better time with a dedicated device, but the fact that the phone is always in your pocket is just so damn convenient.

Your other points are valid.
Ooh, cool! 😁 That detector seems to be working only in “Geiger mode”, which means that it can count the number of X-rays/Gamma particles but it does not estimate their energy. So, the dedicated devices are still better in that they allow you to identify the source of the radiation by measuring the counts and the energy distribution simultaneously.
It probably would not be too difficult to build the open gamma detector into something like a pinephone. I don’t think that has been done yet.
There were a couple projector phones. Samsung Galaxy Beam 1 & 2
Can phones “detect” really high radiation on the camera if it’s high enough or is that film only?
Yes. The camera pixels generate a current in response to light. You can add some filters to block certain wavelengths of light (like UV) from getting to the camera sensor, and tune the pixels so that they respond more to to specific colors. But X-rays and gamma rays can just pass through the filter. Often they will pass through sensor as well, but, in the cases that they do get absorbed by the sensor, they can also produce a current that to the camera’s readout electronics looks like other light would.
The gamma detectors I mentioned are very very sensitive. They respond to single X-ray/Gamma ray particles. These detectors can count how many individual particles collide with a small crystal cube every second. These crystals are special in that they produce a very tiny flash of light when an X-ray or gamma particle collides with them. As an added bonus, these sensors can directly measure the energy of the particles by measuring the strength of the flash, and from this information they can construct not only the total counts but also a spectrum. With this extreme sensitivity these detectors can measure small quantities of radiation that come from space, from rocks, and from other materials.
I looked for a video of a phone going through an X-ray machine, and found these:
https://www.youtube.com/watch?v=E8iSoPhtY3s
https://www.youtube.com/watch?v=V1YaroH6lHA
The white specks that you can see near second 25 (first video) and second 34 (second video) could be a result of the X-rays. I am not sure, but it seems reasonable to me. On contrast, when I put my radiacode through the X-ray machine in the airport the radiacode reacts very strongly and becomes saturated.
Cleverly, even low levels can be detected. I love how creative early smartphone developers could be.

What do you mean? Early apps was all stuff like this that nobody used. Nowadays apps are useful fintech services and photo filter apps that cost less than a coffee per month and fun free games that everyone can play, isn’t that much better?

Even if you use a radio without a license, most of the time, nothing will happen. The FCC (at least, before 2025) wont care if you talk to your friends using radio without a license.
Caveat to this: If you use these radios on amateur bands without licenses, you should expect legal problems. Operating them on FRS, MURS, GMRS, or PLMRS bands is far less likely to upset anyone.
CB radios are still widely used by truck drivers. Listening to the CB on long trips can sometimes be very entertaining.
This is funny, just yesterday I randomly found phones with built-in VHF/UHF radios on Aliexpress. To be fair, they look super clunky and are very expensive for off-brand Chinese phones ($800+), but they do exist. I wonder who buys them.
I’m posting these separately so people can argue about specific devices.
A calculator is still better than a phone in a lot of cases. I haven’t yet met a financial advisor who uses their phone instead of a calculator. It’s often the same issue as with keyboards: touch screens are simply vastly inferior to tactile keys. Few people are willing to carry keyboards around with them, but for those who use calculators a lot, for many it’s worth having a portable, dedicated device.
I did machining inspection for a while and would be dealing constantly with hundreds of data points. Using the table functions on my TI-84 was a godsend. Everyone was writing answers down and transcribing when I joined.
Yeah definitely, I use an HP-49 emulator on my phone for like whenever I want to do just some quick calculation or only have my phone, but I always have an actual HP-49 in my bag because just having real buttons is so much nicer even if everything else is the same
RPN gang taking over
Technically the 49 is algebraic by default but I don’t think I’ve done a single operation in that mode
Pocket knife. Although I wouldn’t be surprised if there’s a phone case out there with a box-knife-like insert for a razor blade.
…infact, brb.
Please send pics of “Knife Phone”.
Well fuck me, turns out not only does it exist, but there are quite a few options!
There’s this dude, which tries to be an entire Swiss army knife. Buyers pretty consistently complain about the build quality though.
This one has a sheath for a removable knife:
And this one uses the mechanism I had envisioned when I was typing my original post, but uh… cuts a little differently than I had expected, and is ofc the clear winner:
Fuck yeah! Knife Phone and Fuck You Phone!
My dumb ass would forget this is my phone case and try to go through TSA lol
Professional work tools come to mind. Laser measures, camera gear, flashlights, 3D scanners, calculators, etc. Sure, there are apps that offer the same functions, but they usually lack the precision and reliability expected from professional tools. There are also some great gaming devices (such as the Analogue Pocket) that probably offer a better experience over gaming on a smartphone.
Oscilloscopes, logic analyzers, and spectrometers.
In these responses I tend to omit obvious items that have no digital component unless there’s an app that can function as the non-digital item. So, no knives or multi-tools.
Along with the mirror, tape measures fall into this category. I’ve tried several digital length-measuring apps, but none provide and accuracy that I’d rely on. I do, however, own a laser measure about the size of a Bic lighter that is extremely accurate; it’s digital, portable, and accurate, so I think it counts.
Even that laser measure isn’t good enough to replace a real, physical measure for detail work, but apps can replace neither except in an emergency, and even then are useless except for coarse-grained measurements.
how bout car keys
Honestly most of the non digital functions of a phone are still inferior to it’s dedicated counterparts, but I would argue that a phone is good enough for 99% of people.
So get a pocket multitool thingy, I always carry one in my bag and it has helped me quite a few time in my life.
Which multi tool? I carry a Benchmade bugout knockoff and a genuine Leatherman skeletool, ifixit Minnow screwdriver set and a generic basic screwdriver with small/large Philips and flathead in my work bag. Oh and a small adjustable wrench… Covers 95% of my work.
Yeah, the issue with multi tools is the same issue with phones; They’re mediocre at a lot of different things. A dedicated multi-bit screwdriver will almost always be better than a multitool. A solid pair of pliers will almost always be better than a multitool. Et cetera, et cetera…
But in a pinch, a multitool is better than nothing. And a multitool is a hell of a lot easier to carry as a “just in case” thing than an entire toolbox of individual tools. As a freelancer I habitually keep a lot of tools in my trunk, but I don’t want to walk all the way out to my car just to tighten one screw. So I also keep a multitool around as a “good enough” solution.
Jeez, nice!
I have this thing from victorinox:
- A pocket notebook and a ballpoint pen, for quick note taking. Edit: add to that a pocket watercolor set and a brush, for quick sketching
- A pocket book, for on the go reading
- My (mechanical) wrist watch
I don’t care if the smartphone can be used to take notes, to read and has an extra precise clock. I much prefer my analog tools. They don’t require upgrade, they don’t need recharging, no one will ever try to stole them (my watch is not fancy at all, it’s just mechanical ;) and, well, I prefer using those.
I’d argue phones are actually better pocket books. Assuming looking at a screen does not bother you:
- it’s much more compact, can be held in one hand and you can carry multiple 800 page books. I’ve never actually seen a pocket book that can fit in a pocket.
- you can adjust font, text size and brightness (some font choices in printed books are just terrible)
- does not need an external light source
- you can quickly look up words and take notes without needing external items
Requiring a battery is a downside but most reading apps consume very little power compared to other apps.
I’d argue phones are actually better pocket books.
It’s obviously a matter of personal preferences, which is absolutely fine.
As far as I’m concerned, I prefer print for these reasons, and for context I have been reading ebooks since I have owned a Palm Pilot PDA in the early 00s, so not reading them is a decision and a choice, it is not an allergy to them or to the tech:
- Print fully respect my privacy.
There is no tracking and no spying on my reading habits. That’s also why I read print newspapers and magazines as much as I can. - No remote deleting of ebooks after purchase.
Like Amazon and Microsoft already did. They refunded customers but that’s not how private property is supposed to work: I pay for a good, I own it its previous owner taht sold it to me can’t decide to enter my home to take it back, even if they were to leave some cash on the table. - No remote editing possible.
No matter if one book or one word in it suddenly becomes unpopular or offensive to anyone. - No notifications, social media, games, email, whatever, to distract me.
- Does not need external light either.
Try to beat day light and at night, or when the sun plays hide 'n seek, well, I have access to this revolutionary piece of high-tech called ‘lamps’ that are lying around absolutely everywhere in our home and, as far as I can tell, are also everywhere I may find myself wanting to read a book. - Does not need batteries, and no recharging.
The same with my watch, btw: no battery, just a spring I rewind every morning after I shower and when I put it to my wrist. It has been working wonder for years and its manufacturer has yet to send my a message telling my watch is tool old and I need to purchase a new model to get updates… because there are none ;) - Does not need app and system updates.
- Does not need Internet.
- Unlike a smartphone, a book itself does not need to be replaced every few years by a new one (aka creating always more e-waste). Talking about phones, here, not e-readers that may last many, many years.
BTW, I seldom need to quickly look up a word either. When I don’t know a word and if I can’t figure out its meaning by using the context it is used in, aka surrounding sentences, I write it down in my pocket notebook (which also requires no battery, no upgrade, doesn’t track me either, etc.) and look it back at home in one of my… paper dictionaries (which don’t push ads into my face, don’t track me, and so on)
you can adjust font, text size and brightness (some font choices in printed books are just terrible)
This is the one advantage I find to ebooks in general (the reader is in charge of the display… depending the app used) but getting that freedom you also instantly lose access to the excellent page layout many publishers work hard on. Sure there are a few dickheads in the field but a majority are not at least those whose catalog I enjoy reading.
And, most ebook page layout is, well, what word did you use? Terrible? You would be right.
I’ve never actually seen a pocket book that can fit in a pocket.
There are (I would say I can fit most poetry books and many plays in my jeans back pocket but I don’t really), the idea is that those small books are easy to carry and are cheap (at least back in then they were supposed to be). It also depends a lot what one reads.
Edit:
it’s much more compact, can be held in one hand and you can carry multiple 800 page books.
I don’t need to carry that. On my desk I have dozens of books and references volumes opened at once (that would be expensive to do the same with multiple phones, right? ;) but I only carry with me a single pocket book so I can read on the go. I do not need my entire library, not even a couple 800, or even 1600 pages books ;)
Edit: if you’re willing to read more of my reasoning to stop using ebooks (I should say ebooks sold by Gafam, as I will still by self-published ebooks when there are DRM-free and there is no print available) and refocus my reading on print instead, I’ve published a couple blog post. Link in my profile.
About half of those issues are solved by drm-free ebooks (or piracy). True, a phone comes with extra work (charging, updating, upgrading every few years) so if you’re not already maintaining one you obviously won’t do it just to read books.
The rest is up to use case. I do need to look up words a lot (usually in other languages) and a bus stop after dark will never have enough light for reading. If you read at home I guess these aren’t issues, but pocket books are meant to be read on the road.
About the formatting there are some books which should absolutely not be read as ebooks cause you’ll miss out on things. But most books are a block of text split in chapters and paragraphs. A phone can absolutely support that.
Anyway, it’s mostly up to use case and preference as you say.
About half of those issues are solved by drm-free ebooks
My iPhone or Kindle will still track my reading habits when I read a drm-free or pirated book (which I tend to avoid as I want to support authors and publishers and I can afford to). For years, I have been using a Kindle that I disconnected from the Web after activation, it was working fine but then I realized we should not have to fight that situation to begin with: our privacy should be respected out of the box. Since I decided to not compromise anymore on that, well, I quit using those device. Like I said, it’s just a personal choice in favor of my privacy (not an allergy to tech itself, just to the way it has been hijacked to become a spying tool)
I do need to look up words a lot (usually in other languages)
So do I (be it in my native French and in the few others I pretend to speak). But like I said, I also never need to get instant access to a dictionary either. So it can wait I get back home.
and a bus stop after dark will never have enough light for reading. If you read at home I guess these aren’t issues, but pocket books are meant to be read on the road.
I would say (pocket) books are meant to be read and would not have any expectation on where and when people are supposed to be reading them. Then, I don’t read when I’m moving (I get sick). I will read at a bus stop or waiting in a line anywhere if there is enough light. If there is not enough, I will either write stuff in my notebook (even dim light is enough to jot down quick notes), or I will think about stuff.
About the formatting there are some books which should absolutely not be read as ebooks cause you’ll miss out on things. But most books are a block of text split in chapters and paragraphs. A phone can absolutely support that.
Typography and page layout was once a thing. It was considered kind of an art form even. I feel a bit sad to see it boiled down to some ‘block of text split in chapters’ but it could also just be a sign that I’m getting old and out of touch. Which is to be expected too ;)
Thx for the discussion, it was interesting.
After seeing the edits, it seems we have wildly different use cases/priorities. I’ll check the blog too, it seems interesting, thanks.

Honestly I’d love to see that because it feels pretty rare right now.
I carry a jailbroken Kobo with wifi disabled. That solves most of the issues you have described here. I sideload DRM-free ebooks. I can’t stand reading text on my phone’s LCD screen (and OLED is worse), but eink screens are totally different, my eyes like them.
Does not need external light either
Lamps exist
That’s exactly what external light means. If you need to sit near a lamp to read your book, then you are relying on external light.
Btw, I agree with the point in general you’re trying to make. Physical books and physical note taking still have a place and are often gone forgotten and underutilized. They can promote greater information retention, due to the tactile experience being mixed into the reading/writing experience.
I carry a jailbroken Kobo with wifi disabled
I used to that with a Kindle. See my answer to the other comment why I decided I did not want to do it anymore.
That’s exactly what external light means. If you need to sit near a lamp to read your book, then you are relying on external light.
The idea was that I do not need an extra light because, well, there are plenty all around but, you’re right, that’s what an extra light means. They’re just already there ;)

The biggest counterpoint I have is simply that I enjoy camping. Good luck finding a desk lamp when you’re 5 miles into the woods. And I’m not wasting my flashlight’s precious battery life on reading.
- Print fully respect my privacy.
Wilderness beacon. Rarely any signal out there. Yes you can an arm and a leg for special service though
I know some phones are starting to work with satellite comms, so these may be replaced by cell phones in the near future. At least currently, I have several friends who still have wilderness beacons.
They’ll never replace PLB/EPIRBs unless they bake in 406Mhz and 121.5Mhz communication. Satellite devices aren’t reliable enough for SAR. I’d even argue that they won’t replace Satellite Communicators - battery life isn’t good enough and the connection stability isn’t good enough
Vibrator
It is a ‘gadget’
Nokia 3310 would disagree,
We had Dildroid like 16 minutes after the initial Android release… 😂🤷
And yet I own more vibrators than I do smartphones
Shank
The galaxy notes solved that… when thay were around.
If you’re looking for an outlet, why not project shop with the aim of making something?
This gives you the opportunity to gadget shop for the things you’ll need to pull off whatever you want to make and will also give you the opportunity to then chase the thing you want to make.
You can make both digital and physical things and with things like CAD, Arduino/Raspberry PI, and IoT you can also blend the two pretty easily.
A very low key example might be a small garden. I’ve put a bit of time/effort into my seed stating setup, including designing and printing parts for my lighting rig. It seems like the setup iterates a bit every year. In addition, every year I spend a decent amount of time thinking about what I want to grow this year and then diving seed catalogues to find some new-to-me verity of something I’ve grown before.
You can also design from scratch speakers and go as far down that rabbit hole as you want to - buy vs build (kit) vs design the amplifier, ditto for the actual speaker, etc.
/a person who likes making things
I would like to subscribe to your newsletter
Haha, the one where I make a bunch of things and fail numerous times along the way or the one where I keep a running list of “this would be a neat thing to try at some point in the future”?
Yes
Good suggestion! Unfortunately I have a Mountain of Shame of unbuilt and unpainted Warhammer models. I need to process those first before picking up another hobby I’ll neglect.
Electric Toothbrush. Keeping up with Dental Hygiene is important too!
Own one. Definitely recommend it and ribbon floss.
Would love to have one, but my neurologist said even slight vibrations in my mouth can fuck with my epilepsy. That means a migraine because my medicine prevents seizures. Going to the dentist is an affair that wrecks me for the whole day.
It’s OK. My dentist thinks electric toothbrushes are too harsh on your teeth and shames anyone who even brings up the subject. So at least 1 dentist thinks it’s junk. He prefers soft bristles that you softly glide across your teeth by hand.
Soft bristles are pretty much the only thing anyone should use, regardless of whether or not it’s electric. Hard bristles are too harsh on your gums.
Laptops! I have a gaming desktop computer and also a gaming laptop that I use if I’m going to be somewhere other than my house for more than a day. Mobile games pail in comparison to what can be played on a decent gaming laptop. I wouldn’t even think about trying to run even a rudimentary 3D game on my 3~ish year old smartphone which has 3-5 seconds of input lag for everything LMAO
