## What is TrackJump?

Test your vertical jump with your iPhone and see the movement behind the number. TrackJump helps athletes and coaches record jumps, review each repetition, and follow progress over time.

START WITH YOUR FIRST JUMP
Use the selfie camera for guided setup. Place your iPhone on a stable support, keep your whole body in view, and stand still while your position is calibrated. Once the camera is ready, jump when you are ready. TrackJump detects each repetition automatically. Try your first jump during onboarding, with no account required.

TEST THE WAY YOU TRAIN
Choose countermovement, arm-swing, squat, drop, repeated rebound, and single-leg tests. Automatic sessions suggest jump types that you can review and correct.

REVIEW EACH REPETITION
See estimated jump height and flight time beside your video. Inspect takeoff and landing frame by frame, review body markers, and correct event timing when needed. Contact-based reactive strength index (RSI) and RSI-modified are shown separately when the recording supports them.

FOLLOW ATHLETES AND PROGRESS
Keep separate athlete profiles, organize coach testing sessions, and retain retests. Compare matching protocols and measurement methods over time. Export results and replay clips to share with an athlete or coach.

KEEP CONTROL OF YOUR DATA
Test as a guest with data on your iPhone, or create an optional account for private backup. Export your records from Profile. Account deletion is available from Profile or the membership screen.

TRACKJUMP PRO
A weekly or yearly auto-renewable subscription or an active trial is required to enter the main app after your first-jump demo. Pro includes recording sessions, video import, athlete profiles, and progress review. Your saved data is preserved when access ends; renew or restore access to use the main app again. The app displays the local price and billing period before purchase. Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings. Deleting your TrackJump account does not cancel an Apple subscription.

Camera measurements are estimates. Lighting, framing, frame rate, technique, and visibility of takeoff and landing affect results. TrackJump is a training tool, not a medical device, certified competition measurement, or substitute for a force plate. Use a clear, safe landing area and tests appropriate to your ability.

### How often is TrackJump updated?

The latest version, 1.1.3, was released on 2026-10-11, indicating recent development activity. Updates typically include performance improvements and new features.

## Version history (last 5 releases)

### 1.2.3 — 2026-10-24

Small fixes and improvements.

### 1.2.2 — 2026-10-23

Small fixes and improvements.

### 1.2.1 — 2026-10-20

- Leaderboard: see where the best jumps rank, with replay videos. Join with a nickname; you can turn videos off, remove a jump or leave at any time.
- A new welcome and first-jump guide, filmed in real sessions.
- Live heights now show as an estimate until the final height is ready.
- If someone else steps in front of the camera, confirm who jumped so your bests stay yours.
- Signing out takes you back to the start.
- Smoother replay video exports.

### 1.2.0 — 2026-10-19

Final jump heights now arrive faster after each recording.

### 1.1.4 — 2026-10-13

More accurate jump heights. TrackJump now times takeoff from the frame your toes leave the floor and landing from the frame they touch down. Earlier versions could count the rise onto your toes as flight and read high, so your numbers may be lower than before. Personal bests start fresh so new jumps are compared like for like.

New: push-off force and power. Add your body weight to see how hard and how fast you push off in standing jumps, for each jump and across a session.

Use a video from your Photos: TrackJump finds and measures the jumps in clips you have already filmed. Rebounds are recognised automatically, each with its RSI (reactive strength index: jump height divided by ground contact time). Standing jumps show dip depth, how far you lower before take-off.

Also: your height stays on screen longer after each jump, setup is steadier when other people are in view, a selfie recording now saves mirrored the way you saw it, and you can share the full recording with body tracking and each jump's height on it.
