Features
Every day, accounted for.
A residency day tracker that counts the way states count, and keeps your log on your device.
Counts
Every state, counted.
Log where you were and see the days in each state and country this year, with each state's day line, the days you have left and whether a home there matters.
- All 50 states and DC
- Statute cited for every rule
- Travel days count in both places
Calendar
A year at a glance.
Each day is colored by where you logged it. Days with no entry stand out, so you can fill them in while you still remember.
- Gaps flagged as you go
- Tap a day to fix it
- Switch years and people
Check-ins
One tap to log today.
Tap Check in here and your browser matches your location to a state or country on your device, using Census and Natural Earth outlines. Nothing tracks you in the background.
- Works on phone and laptop
- Location never leaves your device
- Nearest place used at coasts and borders, and labeled
Federal test
The Substantial Presence Test, built in.
Not a US citizen or green card holder? See your weighted US days for this year and the two before, and how many more days would meet the test.
