I run Kimai under Docker for this. https://www.kimai.org/

Activity watch does all that automatically! Needs some tinkering to setup, especially the android and desktop sync, but it’s there.

I like timeto.me (android). It is designed to log the whole day. It doesn’t seem to support tags, but the checklists might be something similar (?). It doesn’t support exporting to a CSV, but it supports backups and they are in JSON format, so it’s probably good enough.

It’s a relatively new project and visually iOS-leaning, but it’s the best one I found for specifically this problem.

I use Super Productivity for this. Not perfect, but good enough

there are a few time trackers on f-droid that seem to fit thia requirement.

“a time tracker” is one.

How’s your python. Its a pretty simple thing to make in python… It won’t care about the platform you choose to run it on.

I’m at the pub right now, but for a quick solution… I made this. It’ll save as a CSV as it goes.

Just tested on android ide so doesn’t look pretty but I can make up a slicker interface if you want?? I can also package it as a binary and publish on github if you didn’t find something suitable.

Enter the task name, hit start to trigger stopwatch, and stop when you’re done.

Not sure how to codeblock on this app and I cant get it to display right. Im blaming the beer

import tkinter as tk from datetime import datetime

class TaskLoggerApp: def init(self, master): self.master = master master.title(“Task Logger”)
