AI workout coach app
An AI coach
for every set
Film a squat — AI checks your form and catches issues. Workouts, food, and weight, all in one app. Train smarter, not just harder.
iOS 15+ ｜ Sign in with Apple / Google
One app for everything lifting needs
Log, analyze, track, reflect — everything you need is here.
01 ｜ AI Coach
AI watches your form
Record a set. AI pulls 30 key frames, matches them to the exercise, and returns an A/B/C grade plus highlights and next-set tips.
02 ｜ Logging
Three-tier workout structure
Weight, reps, rest, techniques (drop set / cluster), notes — all preserved in history. Use the preset list or add your own exercises.
03 ｜ Food
Snap your meal, AI estimates
Photograph any food. AI estimates calories and the three macros. Recognizes Taiwan convenience store food too.
04 ｜ Weight
7-day moving average
Log daily and see the real 7-day trend line, past the noise of day-to-day water weight.
05 ｜ Fuel
Post-workout store picks
After a session, AI suggests protein options from Taiwan 7-Eleven / FamilyMart based on what you just trained.
06 ｜ Social
Friends activity feed
See friends' workouts, weight, and food. Like and comment — get stronger together.
Frequently Asked Questions
Is Hatch free?+
Core features (workout logging, weight tracking, friends feed) are free. AI form coach, AI food recognition, and AI workout summaries have a daily free quota — upgrade to Hatch Pro for more.
Will my training videos be uploaded?+
No. Video stays on your phone. We only send 30 key-frame screenshots to AI for form analysis. The original video never leaves your device.
Is the AI analysis accurate?+
AI uses the exercise name you entered + key-frame screenshots and returns "highlights + improvements + next-set tip" in plain language. Accurate enough to catch common issues like lower-back rounding, not squatting deep enough, and torso leaning forward.
Can I only log exercises from the preset list?+
No. The preset list covers common lifts, but you can also type any name yourself (e.g. "DB lateral raise," "cable tricep pushdown"). AI matches your name and video content for feedback.
When is the Android version coming?+
Currently iOS only. Android is on the roadmap. Try the iOS version on the App Store first.
Do I need an Apple Watch?+
No. Hatch runs entirely on your iPhone. No watch or wearable needed.
Can I export my training data?+
Yes. In Settings, you'll find "Export workout history" and "Export weight log." Tap to open the share sheet — save to Files, AirDrop, or email. CSV format, opens in Excel / Google Sheets.
