How do I record trips automatically without opening the app?
Use iOS Shortcuts automations: trigger Odo's Start, Pause, Resume, or Stop actions from CarPlay, Bluetooth, NFC, Focus Mode, or the Action Button.
Read full answerHow do I auto-record trips when CarPlay connects?
Create a Shortcuts automation: trigger "CarPlay connects" → run Odo's "Start or Resume" action, and "CarPlay disconnects" → "Pause".
Read full answerHow do I auto-record trips with my car's Bluetooth?
Trigger "Start or Resume" when your iPhone connects to your car's Bluetooth, and "Pause" when it disconnects.
Read full answerHow do I use an NFC tag to start or stop a trip?
Stick an NFC tag on your dashboard, then create a Shortcuts automation: NFC trigger → Odo Start / Pause / Resume / Stop action.
Read full answerCan Driving Focus automatically record my trips?
Yes. Use Shortcuts to trigger Odo's "Start or Resume" when Driving Focus turns on, and "Pause" when it turns off.
Read full answerCan I use my iPhone's Action Button to control trip recording?
Yes. Assign a Odo action (Start, Pause, Stop, or Start or Resume) to your Action Button for instant one-press control.
Read full answerWhat Siri voice commands does Odo support?
Five hands-free commands: Start Trip, Stop Trip, Pause Trip, Resume Trip, and Start or Resume.
Read full answerWhen should I use "Start Trip" vs "Start or Resume"?
Use Start or Resume for one continuous journey with stops. Use Start Trip when you want each leg, vehicle, or activity as its own separate record.
Read full answerHow do I automatically pause or end trips?
Pair every Start automation with a matching Pause/Stop automation on the inverse trigger (CarPlay disconnect, Bluetooth disconnect, Focus off, NFC tag re-tap).
Read full answerStep-by-step: how do I set up a Odo automation?
Open Shortcuts → Automation tab → + → choose trigger (CarPlay, Bluetooth, NFC, Focus, etc.) → search Odo → pick action → set Run Immediately.
Read full answerHow do I set up automations across multiple vehicles?
Create one automation per vehicle, each tied to that vehicle's CarPlay or Bluetooth, and use "Start Trip" so each car's drives are logged as separate trips against the correct vehicle profile.
Read full answerMy automation isn't running automatically — how do I fix it?
Open the automation in the Shortcuts app and turn off "Ask Before Running" so it runs immediately without a confirmation tap.
Read full answerCan I record trips automatically on a daily schedule?
Yes. Use a Time of Day automation (e.g. weekdays at 8am) to start a trip and another at 6pm to stop it — perfect for a fixed daily commute.
Read full answerCan I auto-start trips when I leave home or arrive at work?
Yes. Use "Arrive" / "Leave" location triggers in Shortcuts to start a trip when you leave home, and stop it when you arrive at work or back home.
Read full answerCan I trigger trip recording when I disconnect from home Wi-Fi?
Yes. A Wi-Fi-disconnect automation is a great proxy for "I'm leaving the house" and works without GPS, Bluetooth, or CarPlay.
Read full answerCan my Apple Watch start a Odo trip automatically?
Yes — use a Workout-start trigger so beginning a cycling, running, or other workout on your Watch also starts a Odo trip.
