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-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
Performance HUD (Pro): a GPS performance HUD suited to any activity, not just holding the phone
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 whenever a securely mounted Android phone can capture the action. The same recording pipeline works whether the phone is mounted in a car, on a boat, or on a bike, and Pro's Performance Analytics turns any of those sessions into GPS-estimated speed, distance, and consistency data afterward.

How it works

1
Mount and wait for GPS
Mount the phone securely. VelocityCam waits for a GPS lock before allowing recording to start.
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's Performance HUD adds Max Speed, Best 10s, Best 30s, Course, and Distance From Start readouts.
3
Review, analyze, export
Open the session in the Library, replay with synchronized telemetry, and check Pro Performance Analytics for GPS-estimated speed tests and run history. Export with the HUD baked into the new file; the original recording is never modified.

Local-only by design

The Android app has no account, no cloud upload, no advertising or analytics SDKs, no crash-reporting SDKs, and no background-location permission. Recordings, telemetry, and Route Trace stay on the device. Exports and sharing happen only when you request them.

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?

No. Video, GPS speed, the free Minimal HUD, and the Pro Performance HUD all work with the phone alone. A RaceBox external GPS receiver is optional; Dragy integration is in development.

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. The original recording is left untouched.

What does Performance Analytics measure?

GPS-estimated speed and distance tests, deceleration and sustained-speed windows, attempt history with median/spread/standard deviation, run comparison with splits and deltas, and a personal-bests history. Results are GPS-estimated, not certified timing.

Which Android phones are supported?

Any device running Android 10 (API 29) or newer that has a compatible rear camera, GPS hardware, and storage. Front-camera switching and a Wide lens option are available where the phone supports them. Available recording resolution and frame rate depend on the phone; VelocityCam automatically falls back to a stable supported setting.

Available on Google Play

Install VelocityCam and start recording

VelocityCam runs on any Android 10+ phone with a rear camera and GPS. Record a session, review it with synchronized telemetry, then export and share it.
