About ZTrainer
Master your Self-defense curriculum with smart daily practice.
ZTrainer is your training partner for Self Defense Studios curriculum. It helps you learn — and actually remember — every technique from White Belt all the way to Black Belt, using proven spaced-repetition practice.
WHY ZTRAINER
Belt curriculums are huge. It's easy to drill this week's material and quietly forget everything from three belts ago. ZTrainer builds you a short, focused practice queue every day, mixing new techniques with older ones that are due for review — so nothing slips away before your next test.
DAILY PRACTICE, DONE RIGHT
• A fresh 5-technique queue each day, drawn only from what you've learned
• Automatically balances forms, strikes, defensive techniques, and kicks
• Prioritizes new material first, then resurfaces techniques based on how hard you found them last time
• Log your reps and how each one felt — the app adapts from there
• Bonus and extra-training modes for when you want to drill more
TRACK YOUR JOURNEY
• The full curriculum, White Belt through Black Belt degrees
• Mark techniques as learned and watch your belt progress fill in
• Build daily streaks and see your practice history at a glance
• Detailed dashboard: days trained, category breakdowns, and more
COMPETE WITH YOUR DOJO
• Optional leaderboards for streaks and a rotating Weekly Challenge
• See how you stack up across your dojo or everywhere
• Cheer each other on and keep each other accountable
YOUR PROGRESS, EVERYWHERE
• Works fully offline — no account required
• Optional cloud save backs up your progress and syncs across your devices
• Sign in with Google or Apple; multiple student profiles supported on one device
• Daily reminders so you never miss a session
Built for students, by a family. Train smarter, test stronger.
