The most customizable gym app — built by a gym-goer who actually trains. Log sets fast, design templates, pick your theme. Apple Watch + Live Activity. No ads. FitSimp is the friendlier no-account workout log for anyone who shows up to the gym — first-week beginners, multi-year lifters, runners who lift on cross-training days, anyone in between. Log a set in seconds. Build templates that match your actual schedule. See exactly which lifts moved and which stalled. Apple Watch and Live Activity ship in the box. WHAT YOU CAN DO • Log sets with weight + reps + rest timer. Decimal weights, kg or lbs, asymmetric split weight for dumbbells. • Build templates from scratch or start from a library of curated plans — Full Body, Upper/Lower, Push/Pull/Legs, single-muscle Focus Days, and Conditioning. • Track every workout in a session-by-session history with PR detection, weekly volume, and a calendar heatmap of the year. • Wear your Apple Watch — start, log, and pause a workout from the wrist. Heart rate streams back to the iPhone in real time. • Live Activity + Dynamic Island show your active set, rest timer, and current lift on the lock screen. • Lock Screen widget shows your weekly training calendar, current streak, and recovery at a glance. • Three themes (Crimson, Warzone, Neon Grind), each with light and dark variants. • Apple Health integration — sessions write back as HKWorkout, heart rate reads from your wrist or chest strap. • CSV import and backup export. Your data is yours. WHY THIS APP IS DIFFERENT • No account, no email, no sign-in. Open the app, start logging. • No cloud sync to our servers. Your data stays on your device or in your iCloud Backup. • No ads. No analytics. No tracking SDKs. • Built by a gym-goer who actually trains. Every UI decision had to survive Sunday morning bench day before it shipped. • Most customizable gym app on the App Store — pick your equipment, your themes, your training-day reminders, your weight unit.
