Grinch Club is a round timer for every martial art and combat sport — Muay Thai, kickboxing, boxing, MMA, BJJ, wrestling, karate, taekwondo, judo and more. Made by Grinch Muay Thai & Kickboxing in Lviv for bag work, pads, sparring, rolling and conditioning, and just as handy as a HIIT, Tabata or interval timer. FREE FOR EVERYONE • Four club exercises — Classic Fight, Light / Amateur, Pad Work, Tabata — and the Club Class: a whole class, one exercise after another. • A real ring bell and a coach's voice: a 3-2-1 countdown, a call to fight at the start and to rest at the end. • Train with the phone locked: the round, countdown and what's next live on your Lock Screen and in the Dynamic Island, with a pause button. • Apple Health: sessions save as workouts, with their sport and rounds. Data stays on your device. • History and your days without a miss. • Gym mode: turn the phone sideways for a huge clock you can read across the room. • Plays nicely with your music — cues briefly lower Apple Music or Spotify instead of shouting over them. • Backup bells still ring if iOS closes the app mid-workout. GRINCH CLUB PRO • Thai Heavy Bag and Sparring, your own exercises and every setting: rounds, rest, get-ready countdown, interval beeps. • A coach that calls combos in Ukrainian or English, and your own round-by-round drills. • Your own trainings: build, edit and share them in the club chat. • Seven coach voices and your own sound for every cue. • The timer's look and colors, every fighter pair, .grinchpack packs and your own logo. • The evening reminder that keeps your run of days going. Pro is a monthly or yearly subscription (the yearly plan starts with a free week for new subscribers) or a one-time Lifetime purchase.

Everyone who had the app before keeps everything. Trainings: the plan first A training opens on its plan: every exercise with its rounds, rest and drill, the whole length, and Start. The club's classes and your coach's files sit under Club, your own under Yours, with Edit, Share and Make a Copy in plain sight. Your own drills Write your own drill: a name, an icon and the calls for every round, from the Drills list in any exercise. A shared training carries your drill with it, so the whole club runs the same rounds. Tutorials Short walkthroughs on the real screens: the tour for newcomers, and one for every feature under Settings → Tutorials. Sessions in Apple Health Turn it on in Settings and each session lands in Health as a workout, with its sport, rounds and pauses. Started a workout on your Apple Watch too? It isn't saved twice, and History shows the Watch's calories and heart rate. ### 1.22.0 — 2026-11-02 Grappling fighters MMA, Jiu-Jitsu, Judo and Wrestling pairs: takedowns, throws, guard passes and escapes above the timer. Settings → Fighters. Defense and footwork calls Seven new calls: pull back, fade, parry, sidestep, blitz, catch, switch stance. The new Footwork drill puts them between the strikes. Thirty new calls Single punches and kicks, overhand, check hook, side, axe and hook kicks, spinning backfist and elbow, clinch knees, sweep, duck, roll, cover, pivot, feint, short combos, and the showy ones: superman punch, back kick, flying knee, tornado kick. Three new drills: Fundamentals II, Clinch Work, Highlight Reel. Works on iPad The same app on iPad: a big timer with the round list beside it, exercises in a grid, space to start and → to skip from a keyboard. Combo drills Eight named drills — Dutch Style, Counter Day, Pure Muay Thai, Up and Down and more — call a different plan every round. Five new calls: uppercut, liver shot, body shot, double jab, clinch. Share a training Long-press a training and share it as a file into the club chat. Members tap it and the session lands in their Trainings, as you sent it. Files stop opening after a few days — your choice. Fighters for five martial arts Boxing, kickboxing, karate and taekwondo fighters join the Muay Thai pair. Pick yours in Settings → Fighters. Exercises, Trainings, History Three tabs: the timers are now Exercises, a Training runs your exercises one after another, and History keeps every session. History with streaks Every session you finish, or stop early, is kept with its rounds and minutes — plus days without a miss, your record, best week and monthly totals. A gentle evening reminder when a run is at stake; set the time in Settings. Trainings: a whole class in one go Build a class from exercises — warm-up, shadowboxing, pads, conditioning — and run them back to back. Try the built-in Club Class. Grinch Timer is now Grinch Club The app is growing beyond the round timer, so it now carries the club's name. Everything you had is still here. ### 1.21.1 — 2026-10-28 • New ring bell: rounds now start and end with a real boxing bell, rung by hand. • Hide the last workout card: rather see your list first? Switch off Last workout in Settings → Home Screen. ### 1.21.0 — 2026-10-28 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
