"Wait, what was I supposed to do today?" — this app kills that moment of confusion the second you open it at the gym. ■ See today's workout the instant you open the app Set up a training cycle (2–12 weeks) once, and the app automatically calculates which week and day you're on. Open the app and today's exercises, target sets, and your last recorded weights are already there. Cycles loop back to Week 1 automatically, so progressive overload never stops. ■ Auto-generate 5x5, 5/3/1, PPL, and more Pick your training days and cycle length, and the app builds out a proven program for you — including target weights calculated from your own 1RM. Or build your own plan from scratch, exercise by exercise. ■ A free, fully on-device AI coach Apple's on-device AI turns your training data into plain-language coaching: target suggestions, weekly/monthly reports, rest-day check-ins, and a coach chat that answers set questions about your progress. Everything runs on your iPhone — nothing is sent to a server. ■ Fast logging with wheel pickers Enter weight, reps, and RIR with iOS-style drum-roll wheels — no typing needed. Voice input works too: just say "80 kilos, 8 reps" and the set fills in. Track failed reps and assisted reps, and personal records (1RM PRs) are detected automatically. ■ See your progress Monthly heatmaps, muscle-group volume comparisons, BIG3 1RM trends and a shareable year-end recap image. ■ Privacy & pricing All data stays on your device (SwiftData) — no account, no server sync. No ads, no in-app purchases. Every feature is free. ■ Compatibility Requires iOS 17+. The AI coach requires an Apple Intelligence–capable device (iOS 26+). Available in Japanese and English.
