Your wanderlust, counted automatically. Every country you've been to, every day that counts - tracked privately, offline. Worry less, live more.
Every country you've been to, counted automatically. Day 31 tracks your travels as they happen, keeps a day count for every country, US state, or territory, and works completely offline - your data stays private on your device. Built for wanderlust first, it is also your tax residency and visa companion: select your locations, set minimum or maximum day limits, and simply track.
▶ Privacy: Your personal data stays where it belongs - on your device.
▶ Offline: Day 31 works completely offline so you can stay updated, no internet required.
▶ Set Limits: Easily define min/max day limits for all countries, US States & Territories, and monitor your progress. Stay ahead with customized alerts.
▶ Automatic Location Tracker: Your timeline updates automatically based on your location.
▶ Timeline: Update and review your travel timeline. Easily see a summary day count per jurisdiction for any reporting period.
▶ Photo to Timeline: Generate travel timeline in seconds completely offline using location data from photos without accessing the actual contents.

I need to track my days for tax residency purposes and have tried a few of these apps over the years, this is literally the ONLY one that doesn't require me to login and give them my email phone etc etc so I'm sold.

I didn’t know how easy it could be to make a retroactive timeline just based on location data from my photos. All offline too, kinda crazy

Downloaded this App in November 2025. Worked fantastic until the last week of August 2026. Then they made a huge App Update and now it’s lousy. Very very buggy, and trying to be too complex. Suggest someone spend their money elsewhere if you need tracking APP.
