Coming soon · for all star gyms
Jumps and motions, practised between practices.
HitZero lets your athletes practise the jumps, motions and stretches your coaches assign, at home, with a phone propped up on the floor. Every correction is worded and approved by coaches, and your staff see who practised and what keeps coming up. Nothing filmed at home is kept.
First an email to confirm your address, then one when HitZero opens to gyms. Nothing else, and you can ask us to forget your address at any time. Privacy policy

TOE TOUCH · PRACTICE · NOTHING KEPT
Illustration. The phone follows body keypoints like these. Nothing filmed at home is kept.
How it works
Your coaches assign it. Athletes practise it.
Practice time in the gym is short. HitZero gives athletes a way to work on the details between practices, on the skills your coaches pick.
Coaches choose the practice
Pick jumps, motions and stretches for a team or for one athlete. Athletes practise what a coach has assigned or approved.
At home, one rep at a time
The phone follows body keypoints and checks each rep against the points your coaches teach:
- toes pointed at the top
- chest up
- arms placed, fists tight
- feet together on the landing
See who practised
Your staff see who practised and which corrections keep coming up across a team, so time in the gym can go where it’s needed. The coach makes every call.
Our promise to coaches
Coach-approved, not AI-judged.
HitZero doesn’t score your athletes. It points out one thing to fix, in words coaches wrote and approved, and leaves the judging to the people who coach. No scores for kids, and no leaderboards.
Rep to rep
One fix at a time, in your words.
Each jump gets its own short note, worded the way coaches say it. Fix one thing, jump again, and the notes change with the rep.
Sample set of toe touches. Every correction is written and approved by coaches before it ships.
What it covers
Jumps, motions and flexibility. On purpose.
Jumps
Toe touch, herkie, hurdler and pike, checked at the top of each jump and on the landing.
Motions
High V, low V, T, broken T, touchdown, punch, L and K: arm placement and how even both sides are.
Flexibility
Splits and stretches held hands-free, measured against the athlete’s own start, never a target.
Stunts and tumbling are not part of HitZero. They stay in your gym, with your coaches.
Built for minors
Keypoints, not footage.
Nothing filmed at home is kept
Home practice keeps body keypoints and measurements, not video.
Parents hold the account
Athletes don’t get accounts of their own. A parent or guardian signs in, consents purpose by purpose, and can take that consent back.
No scores, no leaderboards
Athletes see what to fix, never a score or a ranking against teammates.
Delete means delete
A parent can delete an athlete’s profile, or the whole account, from the app.
