Explorer - Device Sensor Data
Own your device's sensor data
Only for iPhone
Free
iPhone
Record GPS tracks enriched with every sensor your iPhone has — barometer, motion, activity, steps — stored locally and exportable anywhere you choose.
Explorer turns your iPhone into a full sensor logger. Start a session and it records your GPS track together with barometric pressure, compass heading, motion and activity data, step counts, and battery state — in the foreground or with the screen locked.
YOUR DATA STAYS YOURS
Everything is stored on your device. No account, no analytics, no ads, no third-party SDKs. Data leaves your phone only when you export it — and you choose where it goes.
RECORD
• One-tap session recording with live dashboard: position, speed, altitude, G-force
• Background tracking that keeps logging while your screen is off
• Log points of interest with a tap - or hands-free with Siri: "Log a POI in Explorer"
• Per-sensor controls and sample rates to balance detail against battery
EXPLORE
• Every session drawn on the map in its own color, with POI pins
• Live compass, motion, and environment views
• Browse every reading in the Data viewer with filters and charts
• Preview any session on a map before deleting it
EXPORT ANYWHERE
• Share ZIPs of CSV or JSONL via Files, AirDrop, or Mail
• Or send data straight to your own server: any HTTP(S) endpoint, POST or PUT, custom headers, Bearer/Basic/API-key auth — credentials kept in the iOS Keychain
• Filter exports by sensor type, session, and date range
• Full schema documentation built into the app (Help → Data Reference)
Explorer asks for location (including Always, for background recording) and motion permissions. Recording happens after you tap Start Tracking or open the app.
