Can I auto-start trips when I leave home or arrive at work?

iOS Shortcuts supports geofence triggers — your iPhone notices when you arrive at or leave a saved location and runs an automation. This works without CarPlay, Bluetooth, or any extra hardware. In the Shortcuts app: Automation → + → "I Leave" → choose Home → add Speedometer's "Start or Resume" action. Create the inverse for "I Arrive" at Home → "Stop Trip". Great for: walking commuters, cyclists who don't want NFC tags, and anyone whose journey isn't tied to a specific car. Tip: precision improves over a few days as iOS learns your typical routes.
