Turn Your Android Phone into a Telemetry Camera
A telemetry camera records video and GPS data at the same time so the numbers on screen match what actually happened. VelocityCam does that on a phone you already own: rear-camera video (with a front-camera switch before recording on supported phones) and GPS-derived speed, captured together and kept synchronized during playback and export. Pro adds a Performance HUD built around GPS metrics, plus a full Performance Analytics workspace for reviewing GPS/GNSS-estimated results afterward.
What VelocityCam records
Every recording carries video plus a stream of GPS samples that the app aligns to the video timeline. You review the ride the way it happened, and exports include the same live HUD you saw while recording.
- GPS-derived speed in MPH or KM/H
- Pro HUD profiles: Telemetry (matched GPS readout pairs), Performance (live GPS performance testing), and Boat Racing (rolling-start boat tests)
- Live GPS status and elapsed recording time
- Front/rear camera switching before recording, where supported, plus a Wide option when a supported wide rear lens is detected
- Resolution Auto/4K/1080p/720p/480p and 30 or 60 FPS, HDR where supported, with automatic fallback to a stable setting
- Portrait and landscape recording, including reverse portrait for windshield mounts
Who uses it
Drivers, riders, boaters, off-roaders, ATV and UTV crews, and track-day enthusiasts use VelocityCam to capture the action with an Android phone. Handheld recording is supported; mounting is optional and helps keep footage steady. Never handle the phone while operating a vehicle. Pro's Performance Analytics turns sessions into GPS/GNSS-estimated speed, distance, and consistency data afterward.
How it works
- 1
Position the phone and wait for GPS
Hold the phone safely or position it securely; mounting is optional. GPS readiness is required before recording begins. Never operate the phone while driving or riding.
- 2
Record with a live GPS HUD
Tap Record (or long-press for a three-second delayed start). The Minimal HUD keeps things simple; Pro adds the Telemetry HUD (Max Speed, Best 10s, Best 30s, Course, Distance From Start, and more), the live-testing Performance HUD, and the Boat Racing HUD.
- 3
Review, analyze, export
Open the session in the Library, replay with synchronized telemetry, and check Pro Performance Analytics for GPS/GNSS-estimated speed tests and run history. Export with the HUD baked into the new file; the original recording is never modified.

- Attempt History (median, spread, standard deviation) and Run Comparison with splits and deltas
- Performance History with personal bests and an interactive Time/Distance analytics timeline
- CSV telemetry export, plus GPX and KML route export
- Watermark control (standard, custom text, or none)
- Session notes and activity types
Local-first by design
The Android app has no account, no cloud upload of recordings, no ads, and no background-location permission. Recordings, telemetry, and Route Trace stay on the device; the app sends only technical usage analytics and crash diagnostics, described in the Privacy Policy. Exports and sharing happen only when you request them.
Device requirements
- Android 10 or newer
- Compatible rear camera (front-camera switching before recording, where supported)
- GPS hardware
- Free storage for recording and export
Frequently asked questions
What is an Android telemetry camera?
It's a phone-based camera that records video and GPS data at the same time. VelocityCam combines rear-camera video with GPS speed so the on-screen readouts stay aligned with the footage during recording, playback, and export.
Does VelocityCam require external sensors?
Not for normal use. Phone GPS supports recording with the free Minimal HUD or a Pro HUD. A supported RaceBox Mini, Mini S, or Micro receiver can provide optional external GNSS; RC use relies on external GNSS. Dragy integration is in development, not currently shipped.
Does VelocityCam upload recordings?
No. Video and telemetry stay in app-private storage. Exports are only created when you ask for them, and sharing only happens after you choose a destination in the Android share sheet.
Can the telemetry appear in the exported video?
Yes. When you export, the selected HUD is composited into the new MP4 file so the numbers travel with the clip.
What does Performance Analytics measure?
GPS/GNSS-estimated speed and distance tests, saved custom tests, deceleration, sustained-speed windows, speed bands and thresholds, attempt history with median/spread/standard deviation, run comparison with splits and deltas, and personal-bests history. Results use phone GPS or supported external GNSS and are not certified timing.
Which Android phones are supported?
VelocityCam requires Android 10 (API 29) or newer, a compatible rear camera, GPS hardware, and storage. Compatibility and recording options depend on the device; these requirements are not a guarantee for every Android phone. Front-camera switching and a Wide lens option are available where the phone supports them. VelocityCam falls back to a stable supported capture setting where needed.
Install VelocityCam and start recording
VelocityCam runs on Android 10 or newer phones with the required camera and GPS hardware; camera features vary by device. Record a session, review it with synchronized telemetry, then export and share it.
