Free, no account, no ads, no limits. Log a set in two taps, the rest timer starts on its own, and everything stays on your phone. Seryz is a workout log built to be used standing up, in the gym, between two sets. Logging a set takes two taps. No loading, no connection, no account. LOG, DON'T CONFIGURE Weight, reps, tick it off. Last session's numbers are already filled in, so most of the time you just confirm. The rest timer starts on its own and keeps counting on the Lock Screen and Dynamic Island, even with your phone in your pocket. YOUR RECORDS, FOUND FOR YOU Heaviest weight, more reps at the same load, best set volume: Seryz checks every completed set against your entire history and tells you right there. When you hit the top of your rep range on every set, it suggests the next load. LIFTING AND HIIT IN ONE APP Build your own strength routines or start from a ready-made template: Full Body, PPL, Upper / Lower, dumbbells at home, bodyweight. Plus hands-free timed circuits looping work and rest, with sound and haptic cues on every transition. Tabata, full body HIIT and express cardio are included. 206 EXERCISES, OR YOUR OWN A catalog of 206 exercises sorted by muscle and equipment, with demo videos. Create your own, swap one mid-workout, chain two into a superset, mark a set as warm-up, drop set or to failure, log your RPE. STATS THAT ACTUALLY HELP Load and volume curves per exercise, estimated 1RM, weekly volume over twelve weeks, muscle split, worked-muscle map, streak of consecutive weeks, body weight tracking. Your full history stays browsable and editable after the fact. APPLE HEALTH Finished workouts can be saved to the Health app, and body weight imported from it. Both are optional; the app works fully without them. ACTUALLY FREE Every feature, for everyone, with no cap on routines, exercises or history. No subscription, no in-app purchase, no ads, no pro version. ACTUALLY PRIVATE Everything is stored on your phone in a local database. No account to create, no server, nothing sent anywhere, no trackers. Export your data any time as CSV or a full JSON backup, and import it back on another device. IN YOUR LANGUAGE English, French, Spanish, Italian, German, Portuguese. Kilos or pounds. Dark or light theme. Seryz is not trying to bring you back every day or sell you coaching. It is a log. It is fast, it is yours, and it will stay that way.
