Your swing, honestly rated.
Film one swing. TrueTen measures it on your phone and gives you a strict rating out of 10, always with its margin of error, then a weekly plan built around the one change that matters most.

Strict, and honest about it
Only tour-level swings score 10. Every number comes with its margin, the way a measurement should, and anything the phone can't judge precisely enough is left out of your rating instead of guessed.
How the rating works: what's measured, where the margin comes from, and why 10 is reserved for tour-level swings.
What you get
One camera is enough
Face-on from about 3 metres, hands-free: tap record, walk to the ball, swing. Add a down-the-line clip if you like, for swing path and hand depth.
A plan that fits your week
Your days, your minutes, where you practise and what you have. One swing change at a time, with drills and a re-film checkpoint judged against its margin.
Practice mode
Every swing measured as you hit balls, a slow-motion replay and a spoken cue, so you can keep your eyes on the ball, not the screen.
Progress you can trust
Ratings over time with their margins, checkpoints passed, practice streaks, a monthly report and side-by-side comparisons.
Private by design
- Your swing is analysed on your iPhone. Videos stay on the phone unless you back them up to your own iCloud.
- No account, no sign-in, no ads, no analytics, no tracking. We don't run servers that hold your data.
- Export everything, or delete everything, from Settings › Your data.
Warm up first. Stop any drill that causes pain. Coaching information, not medical advice.
