LiftLog

LiftLog is an open-source workout journal for iPhone and Android built around one goal: making strength training quick to log without unnecessary complexity. Your workout history stays on your device, with no account required and no cloud lock-in.

Track workouts with one-tap set logging, automatic rest timers, progressive overload suggestions, workout planning and detailed progress charts. Everything works fully offline, making it ideal for gyms with poor reception or users who value privacy.

LiftLog is free and open source, with all core workout tracking features available at no cost. An optional one-time purchase unlocks AI-generated workout plans while keeping the core logging experience subscription-free.
