Questions people actually ask

What does BodyBench measure?

68 metrics grouped into 10 dimensions: cardio & metabolic, strength, power, endurance, mobility, balance, agility, neuromuscular control, body composition, and recovery as a trend. Posture is screened as a separate eleventh dimension. Each result is scored against population norms for your age and sex, then normalized into a single 0–100 Body Score.

What is Body Score?

One number from 0 to 100 that puts every test on the same scale. Your tests come back in seconds, kilos, centimetres and watts per kilo, which can't be compared to each other. Body Score converts each of them against age- and sex-matched norms so you can see which dimension is lowest. It's a common currency, not a percentile, so the app shows it with the tier and the group it was calibrated against: Good tier · vs men 30-39.

How long does the assessment take, and what equipment do I need?

The baseline assessment takes about 10 minutes, and most of it needs nothing but floor space and your phone. Countermovement jump, single-leg balance, FMS screens and posture are all captured with the camera. Some tests do need equipment or manual entry: 1RM lifts, a 30m sprint, T-test agility and drop-jump RSI can't be measured by a phone alone, and we don't pretend otherwise.

How much can I trust the jump height?

For tracking your own progress, which is what it's built for. We don't claim lab precision, we claim lab cadence: a number you get every four weeks is worth more than one you got once, and trend is what training decisions actually run on.

The mechanics are simple. Your phone records the jump at up to 240 fps and analyses the video afterwards rather than live, so the frame rate becomes timing resolution. Height comes from how long you were in the air. When the app can't track you cleanly enough through the flight, usually low light, loose clothing, or standing too far back, it returns nothing and asks you to jump again instead of guessing.

If you want to settle a jump exactly, open the filmstrip and pick the takeoff and landing frames by eye. That takes the automatic detector out of the loop, and the only error left is the frame rate itself: at 240 fps one frame is about 4 ms, which puts the theoretical floor near half a centimetre on a typical jump.

Can I correct a jump the app got wrong?

Yes. Open the filmstrip and pick the takeoff and landing frames yourself. The height recalculates as you scrub, so you can see exactly what each frame is worth. The app marks where its own detector landed, so you can see how far off it was. Frames you confirm are kept as labelled samples and used to tune the automatic detector.

Is BodyBench free?

Testing is free forever: all 10 dimensions, every test, no card required, plus one free Coach report. A BodyBench Coach subscription unlocks unlimited Coach reports, periodized training plans, and meal and posture analysis. Pricing is set in the App Store and shown before you subscribe.

How often should I retest?

Every four weeks. That's the length of a training block, and it's why Coach asks you to retest the exact dimension it targeted, so you find out whether the block worked instead of assuming it did. Testing more often mostly measures noise; testing less often means a bad plan runs for months before you catch it.

Is there an Android version?

Not today. BodyBench is iPhone-only, because the camera-based tests depend on Apple's on-device pose estimation and the Health integration. There's no web app either.

Does my data leave my phone?

Your results live on your device and there's no account or login. When you tap to request an AI Coach reading, a training plan, or a meal or posture analysis, that one request is sent through our backend to a third-party AI provider for processing. It isn't stored, and nothing goes to us in the background.

One exception, and it isn't us: so a reinstall or a new phone doesn't lose your history, the app backs your data up to your own private iCloud. It's on by default, you can turn it off under Profile & Settings › iCloud, and it goes straight from your phone to your Apple ID — never through our servers. Erasing your data from inside the app clears that backup too.

Is this a medical or diagnostic tool?

No. BodyBench is a fitness and training tool, and every reading is an estimate for training guidance. Posture and body-composition screens flag things worth looking at; they are not a diagnosis. See a healthcare professional for medical concerns.
