Hatch is an AI workout coach in one iPhone app. Record a set of squats — Hatch sends key video frames to a vision AI for analysis. Snap a photo of your meal — AI estimates calories and macros. Log every set, track your weight, and see your progress take shape. Not just a logger. A coach in your pocket. [ Core Features ] • AI Form Coach Film a squat, bench, or deadlift. Hatch automatically extracts 30 key frames and sends them to a vision AI. You get specific feedback like "shift your weight slightly forward, open up the knee angle a bit more, try this on your next set." Not vague encouragement — real coach-style notes. • Full Workout Logging Weight, reps, RPE, rest time, advanced techniques (Drop Set / Pause / Cluster / Iso Hold), supersets — every field intermediate and advanced lifters need. Three-tier structure (Workout > Exercise > Set) makes history easy to scan and progress easy to see. • Food + Calorie Tracking Snap your meal. AI estimates calories, protein, carbs, and fat. Weight, food, and training all live on one page — cut or bulk without guesswork. • Post-Workout Convenience Store Picks After a hard session, AI suggests protein options from Taiwan 7-Eleven / FamilyMart based on what you just trained. The right protein at the right portion — no standing around the store wondering. • Built-In Training Plans PPL (Push / Pull / Legs), Upper/Lower Splits, Beginner Full Body. Don't know how to program? Pick one and start. • Social Feed See friends' workouts, weight logs, and food posts. Like and comment to keep each other accountable. Add by friend code. [ Why Hatch ] • Videos Stay On-Device AI analyzes key frames in the cloud, but the video itself never leaves your phone. Discarded after analysis. No training data harvested. • Cloud Backup Only For Signed-In Accounts Apple / Google sign-in syncs training, weight, and food data automatically. Switch phones safely. • Built By A Lifter Hatch is made by one engineer who lifts every day. Features ship because "I want to use this myself," not to hit feature checkboxes. [ Who Hatch Is For ] • Already train consistently and want a complete log • New to lifting and want AI to check your form • Cutting / bulking and need food tracking too • Train alone and want friends to keep you accountable • Tired of juggling three apps for training, food, and weight [ Pro Subscription ] Hatch is free to download.
