How it works
What Chrono does
02
Track your time automatically
Chrono runs in the background and tracks the time you spend in each country, state, and city. No spreadsheet, no manual log.
03
Build a defensible record
A reliable timeline of where you've been. Mark moments as Chrono Verified with a biometric check when proof matters.
The outcome
What you get with Chrono
A reliable, continuous record of where you've been across countries, states, and cities, over time.
Goals that run automatically. Set a residency or travel threshold once. Chrono tracks your time and keeps your record up to date.
When it needs to be defensible, a biometric check makes it Chrono Verified. A higher confidence record of presence.
The tools
Understand your exposure
The rules are simple to state, but easy to mis-track. A missed trip, a partial day, or a misunderstood threshold can change the outcome.
Manual to automatic
Once by hand. Then never again.
One trip, one calculator, one answer is fine. But the calendar keeps moving, the trips keep coming, and the day you forget to log is often the one that matters most. Chrono runs in the background so you don't have to.

Who it's for
Who uses Chrono
Used by people managing tax residency, navigating Schengen limits, monitoring US state exposure, and maintaining a reliable record of their travel.
Verified presence
A biometric check turns a moment into Chrono Verified. A higher confidence record when proof matters, not just a log of where your phone was.
As recognized in
"High earners need to log their days and prove the location of everything from pets to Pelotons to show they've truly changed residency."
