Resilient recording
Pause, resume, and recover an unfinished activity after an interruption without filling gaps with invented data.
An outdoor record you control
Your route, held with care.
Témoin records an outdoor activity on your iPhone, explains sensor gaps in plain language, and keeps the result on your device until you choose to export it.
See how it worksLocal by default. Share only when you decide.
Built for honest context
A calm record, not an alarm.
Visible quality
Accuracy, timing, and unusual jumps are surfaced as cautious context—never as accusations or guarantees.
Yours to export
Keep sessions on the device or share JSON, GeoJSON, or GPX through the system share sheet. No account required.
Important limits
Témoin is a recorder, not an emergency service.
It cannot guarantee personal safety, prove where a person was, or establish that sensor data is authentic. If you are in immediate danger, contact local emergency services when you can do so safely.
