- 03
Climb the boards
Your best ready score unlocks Rank Road tiers and adds to your Clan total. Video stays private unless you opt in.
Recording tips
- Record vertically (phone upright) with your full body in frame and good light.
- 60 fps / 720p recommended. 30 fps minimum — lower fps reduces accuracy.
- Exactly 30 seconds of continuous skipping. One person in frame.
- We optimize 4K and longer clips in your browser before upload (max 80 MB).
FAQ
How does the JumpFlow 30s Skip Challenge work?
Sign in, upload a vertical ~30-second rope-skipping video, and JumpFlow AI counts your jumps. Your score appears on the public leaderboard; video playback stays private unless you opt in and pass moderation.
Is the AI jump count free?
Yes. The Global 30s Skip Challenge is free to enter. Rate limits apply to prevent spam (including daily upload caps).
What video quality should I record?
Record vertically with your full body in frame. 60 fps and 720p are recommended; 30 fps is the minimum. We optimize longer or higher-resolution clips in your browser before upload (max 80 MB).
Can JumpFlow use my video to improve AI counting?
Only if you give research consent. Scores can still be public while the video stays private. You can delete your submission later; promoted labeling copies are separate admin-owned assets.
