Full feature set

The simpler it is, the more they stick with it

No counter, no wristband. Stand the phone up and start jumping.

📷

Jump once, count once

The AI watches your body and counts. Works in regular indoor light, with everyday clothes.

🔥

Streak grows on its own

The home screen answers "did I do it today?" — and you watch the streak chain getting longer.

🏆

47 badges to unlock

First 50-streak. 7 days in a row. First HIIT finished. Every milestone has its own little reward.

🏃

Don't know how to train? Just follow.

HIIT, Tabata, Stair, Sprint, Endurance, Pyramid — six rhythms, each with its own beat-based BGM.

🎬

A highlight clip every time

The video lands in your photo library with stats baked in — drop it in any chat with one tap.

🤜

Invite a friend, jump apart

Hand out an invite code or QR. They jump too. Both results show up on a single VS card.

Privacy

Videos stay on the phone. So does everything else.

No accounts, no logins. No third-party analytics, ad, push, or social-sharing SDKs.

🔒

Camera frames never leave the device

The AI looks at each frame, counts the jump, then discards it. Nothing is uploaded. Ever.

🚫

No phone numbers, no contacts

Sign-up isn't a thing here. Friend Challenge syncs only nicknames and scores, auto-cleared after 30 days.
