About this app

Pocket Performance Lite is the entry-level version of Pocket Performance, built for Android drivers who want to try phone-based car acceleration testing before moving up to the full app.

Start with Lite, add your car, complete vehicle and phone calibration, then record a focused 0-62 mph / 0-100 km/h-style acceleration run without needing an ECU connection, OBD device or dedicated timing hardware.

Pocket Performance Lite is powered by a 7-layer telemetry system plus vehicle calibration. It is designed to give drivers a more structured testing experience than a basic stopwatch, rough GPS speed check or simple speedometer app.

Try car acceleration testing from your phone

Pocket Performance Lite focuses on one core test flow:

- 0-62 mph / 0-100 km/h-style acceleration testing
- Vehicle and phone calibration
- Saved run history
- Run Confidence
- Lite Brag Cards
- One-car garage
- Result sharing
- Website access
- Full app upgrade path
- No subscription

The aim is simple: give Android drivers a clean way to try Pocket Performance, save results and see how consistent their runs are over time.

Calibration-based telemetry

Pocket Performance Lite uses phone sensors, GPS telemetry and vehicle calibration to help create useful, repeatable acceleration results.

Instead of acting like a basic stopwatch, the app is built around a calibration-first system. Add your vehicle, complete the calibration flow, then use Lite to record acceleration tests directly from your Android phone.

Run Confidence gives extra context to each result so you can better understand the quality of the run and the data behind it.

Built for the full Pocket Performance system

Pocket Performance Lite is the starting point. The full Pocket Performance app unlocks more testing modes and advanced features for drivers who want to go further.

Full Pocket Performance adds:

- 0-100 mph testing
- Quarter mile timing
- Half mile timing
- Top speed mode
- 100-200 acceleration testing
- Multiple-car garage
- Private results, history and run details

The one-time Pro Pack adds:

- Proof video with HUD overlay
- Qualifying public leaderboard uploads
- Track Mode
- Challenge runs
- Brag Cards, sharing and export
- Advanced telemetry features

Lite lets you try the core acceleration testing flow first, then move up to the full app when you are ready for more modes, proof runs and leaderboard competition.

Made for car enthusiasts

Pocket Performance Lite is built for car enthusiasts, modified car owners, performance drivers and Android users who want a focused car acceleration timer with calibration, saved runs and shareable results.

It is not dyno software, a horsepower calculator, a torque calculator or a diagnostic tool. Pocket Performance Lite is focused on phone-only car acceleration testing.

Safety and legal use

Safety is essential. Pocket Performance Lite is designed for safe and legal use only.

Users must follow all road laws and only perform vehicle testing in safe, suitable and legal locations such as private land, controlled environments, test facilities or track days.

Do not use Pocket Performance Lite for street racing, illegal racing, dangerous driving or antisocial driving.
