TrainWiz
Pokémon-styled workout RPG — real reps level up your monster
Most fitness apps feel like a spreadsheet with guilt attached, so people quit by week two. TrainWiz makes it a game you actually want to open. Prop up your phone, do real bodyweight exercises like squats or push-ups, and on-device AI counts every rep (no video ever leaves your device). Those reps power a real RPG: battle through 100+ stages, catch and raise 100+ monsters, and evolve your team. Plus live co-op, train with a friend in real time. No gym, no equipment. Free on iOS & Android.
Hey everyone! 👋
I'm Taka, maker of TrainWiz.
Confession: I've downloaded probably ten fitness apps in my life, and deleted every single one by week two. The streaks, the guilt, the spreadsheets — none of it made me actually want to move.
So I built the thing that finally worked on me: cute monsters you raise with real exercise.
How it works:
🏋️ Prop up your phone and do a few real bodyweight moves like squats or push-ups — on-device AI counts your reps (no footage ever leaves your phone)
🐣 Every rep feeds your buddy: XP, daily streaks, and real evolutions from hatchling to fully grown
🗺️ It's an actual RPG — battle through 100+ stages and catch & raise 100+ monsters to build your team
😢 Skip a day and it gets a little lonely (gentle nudge, not guilt trip)
👯 Invite a friend to a live co-op session and work out together
It's free on iOS and Android, made for beginners and busy people — five-minute quests, no gym, no equipment.
I'd genuinely love feedback: does the pet make you want to come back? What would make day 14 as fun as day 1? And which buddy did you pick? 😄
Thanks for checking it out!
Does the on-device rep counting actually work reliably in a dimly lit room, or does it need decent lighting and a clear phone angle to avoid miscounts?
Played around with this for a few minutes and the on-device rep counting actually picked up my squats without needing to fiddle with positioning, which was surprising. The monster catching loop hooked me way more than I expected for a fitness app.
It was convenient that I could just set my phone down and exercise, and it would count my reps automatically. Since I didn't have to keep track myself, I could focus on my form and movement.
It was also great that it made exercising fun, like playing a game, rather than just going through the motions. I think even people who aren't particularly athletic will find it easy to stay consistent while playing.
There were times when it didn't count my reps if I moved a bit too slowly, but I think it is amazing that it can recognize my movements using only a smartphone. If it becomes possible to save my training records, I would love to keep using it.
How does the on-device AI handle different angles or if I prop my phone at a weird spot, does it still count accurately or do I need to keep adjusting it every workout?
Squats got pretty tiring by stage 20 but the rep counter is surprisingly accurate, made me actually look forward to opening it.
The on-device rep counting is a really thoughtful call, keeps things private while still feeling responsive. Love that you tied it straight into an actual RPG loop instead of just slapping a streak counter on it.
