TaxStayTracker

If you travel for work or live between countries, you've probably worried about the 183-day rule. Spend too many days somewhere, and you might owe taxes there. But keeping track manually? It's a mess of calendars, receipts, and guesswork.

TaxStayTracker handles this for you. It quietly tracks which country you're in and counts your days. No more spreadsheets or trying to remember if that Berlin trip was 4 days or 5.

Your data stays on your device. Period. We don't collect anything, don't sync to the cloud, and can't see where you've been. It's just you and your phone keeping track.

What it does:
- Automatically detects when you cross borders
- Counts days in each country per year
- Shows you how close you are to 183 days anywhere
- Lets you add trips even beforehand, to plan your year
- Exports clean PDF and CSV reports for your accountant

Perfect if you're a digital nomad, consultant who travels for clients, or anyone juggling multiple countries. The app runs quietly in the background, barely touching your battery.

The interface is straightforward – no tax jargon or confusing charts. Just clear numbers showing where you stand. When tax season comes around, export a PDF or spreadsheet with all your travel dates. Your accountant will thank you.

Built by people who actually deal with tax residency questions. We made this because we needed it ourselves and to showcase our ability to build apps.
