What it does

• Fast set logging

  Weight, reps and effort per set, with rest timers that alert you on time. On iPhone, the timer follows you to the Lock Screen and the Dynamic Island.

• Routines that progress

  Build routines and a weekly schedule, or start from a ready-made plan. Progression rules suggest the next weight, so each session starts with a target.

• Progress you can see

  Charts for every exercise, personal records, estimated 1RM, body weight and measurements, muscle balance and recovery.

• Health, widgets and Siri

  Workouts and weigh-ins go to Apple Health or Health Connect if you allow it. Widgets on both platforms; Controls and Siri on iPhone.

• Your data, kept safe

  Optional automatic backups after each workout, encrypted backups with a passphrase, App lock with Face ID or a fingerprint, and imports from Strong, Hevy, FitNotes, gravl and JEFIT.

• Optional AI assistant

  Bring your own OpenAI, Anthropic or Gemini key. It reads your plan and log, answers questions and suggests changes you approve one by one. Off by default, free, and the only feature that sends your training online. How to get a key
