3Days
A free tracker for time off. Pick your days, add a note and see how much leave remains. Everything syncs to your own Google Drive.
The idea
I kept losing track of how many days off I had left at work. I would count them by hand, count again and somehow get a different answer. It was a small, stupid problem, so I designed and built my own solution.
The first version came out in 2022. It worked offline, needed no account and kept its data in the browser. That prototype proved the idea and still lives at 3days.netlify.app, unchanged since then.
In 2026 I rebuilt the app. 3Days is now an installable PWA that works offline and syncs directly with your Google Drive. It has no separate account or server, so it does not keep another copy of your data. Choose the days you are taking, give them a title and the dial updates straight away.
The app is free and has no ads. It works in English and Polish, includes light and dark themes, and remains usable without a connection.
