TrainWiz is a free-to-play fitness RPG mobile app that converts real-world exercise into experience points for a virtual pet, which levels up and evolves as you stay active.
What is TrainWiz?
TrainWiz is a mobile fitness game for iOS and Android that uses your phone's camera and on-device pose detection to count exercise reps and feed a virtual buddy. It takes your physical movements—squats, sit-ups, walks—as input and produces XP, level-ups, and in-game progression through a story mode and creature-collecting Dex. It's made by Zen Labo and is available from the App Store and Google Play.
Key Features
- On-device rep counting — The app detects your movements through the camera and counts reps automatically, so you don't manually log each set.
- Buddy system — A virtual pet reacts to your activity, gains XP, and evolves through three forms: Hatchling (levels 1–5), Teen (6–14), and Fully grown (15+).
- Live co-op workouts — Start a real-time session, invite a friend, and your buddies appear on screen together; accepting an invite is always free.
- Story mode & Dex — Battle through themed adventure stages and collect the creatures you defeat to fill your Dex.
- Streaks & quests — Build streaks and complete daily quests; even a five-minute session counts as a win.
- No equipment required — Designed for bodyweight moves in living rooms, kitchens, or tiny apartments.
Who should use TrainWiz?
- Anyone who struggles with workout consistency — Use the buddy system and streaks to turn 'I should work out' into a quick, rewarding session.
- Gamers and RPG fans — Enjoy leveling, evolving, and collecting mechanics that make exercise feel like a game.
- Friends and family — Use co-op sessions to work out together remotely, cheering each other on in real time.
- People without gym access — Perform bodyweight exercises anywhere, with no special equipment required.
What can you do with TrainWiz?
- Home exercisers: Set up your phone, do squats or sit-ups, and watch your buddy level up as the camera counts reps automatically.
- Co-op partners: Start a live session, send an invite, and work out together with both buddies on screen.
- Collectors: Battle through adventure stages to defeat creatures and complete your Dex over time.
- Streak builders: Use daily quests and streaks to stay consistent, knowing every session counts.
How does TrainWiz work?
Open the app, prop up your phone, and perform a movement like a squat—on-device pose detection counts the reps and converts them to XP. Walks or quick sessions can also be logged manually if you prefer not to use the camera. As XP accumulates, your buddy levels up and eventually evolves.
Pricing
TrainWiz is free to download, raise a buddy, build streaks, and join friends' live sessions. A Pro upgrade unlocks hosting your own co-op invites and a few extras, but the core loop costs nothing.
FAQ
Do I need a gym or equipment?
No. TrainWiz is built for couches, kitchens, and tiny apartments. Bodyweight moves, walks, and quick sessions all feed your buddy, and any weights you have also count.
Is TrainWiz really free?
Yes. The core experience—raising a buddy, earning streaks, and joining live sessions—is free. A Pro upgrade is optional for hosting co-op invites and a few extras.
How does the camera rep counting work?
It runs on your device to recognize movements and count reps, then turns them into XP automatically. You can also log sessions manually if you'd rather not use the camera.
What happens if I miss a day?
Your buddy waits for you. The flame may dim, but nothing is deleted and there's no shaming. TrainWiz is designed as a gentle nudge, not a drill sergeant.
