Skates is a skill tracker and practice log for figure skaters. From the very first steps on ice to spins, jumps, and turns, in any order. YOUR TRAIL Every skill is a stop on your trail. Work on more than one at once, mark each one done when it's truly yours, and watch the path light up behind you. Six levels per track, and you move at your own pace. EVERY SKILL, MADE CLEAR No guessing what "done" means. Each of the 143 skills comes with a clear technique cue and an honest check, so you always know what you're aiming for. LOG EVERY SESSION Note what you practiced and how it went. No streaks, no guilt just a record of your time on the ice that grows with you. You'll be able to see how many days / sessions it took to complete your skills. BADGES THAT MEAN SOMETHING Finish a skill and see exactly what it took: how many days, how many sessions. Hard work pays off, and Skates shows you the receipt. FREESTYLE MODE Already skating? Skip the roadmap. Freestyle mode unlocks spins, jumps, and turns with nothing gated. Track whatever you're working on, in any order. BUILT FOR SKATERS • Four tracks: First Steps, Basic, Adult, and Free Skate • Progress syncs privately through your own iCloud • No account to create, no data collected • Works fully offline at the rink Skates is a self-assessment tool for tracking your own practice. It isn't a substitute for a coach or an official skating program, and completing a skill in the app isn't a credential. SUBSCRIPTION Try everything free for 7 days, then $4.99/month or $18.99/year, or unlock forever for a one-time $29.99. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
