Split your time between the U.S. and Canada? One miscounted trip can trigger U.S. tax residency or put your provincial health coverage at risk. 49th Parallel Day Tracker keeps count for you.

What it does:

Tap-to-log calendar — mark each day U.S. or Canada in seconds
Automatic IRS Substantial Presence Test math — this year, 1/3 of last year, 1/6 of the year before
Real-time alerts as you approach the 31-day and 183-weighted-day thresholds
Provincial health-coverage day tracking for all 10 provinces and 3 territories
Year-by-year breakdown plus a forward-looking "safe days" plan for next year
Export your day log (CSV) and summary (PDF) for your accountant
