When it comes to workout tracking, few apps manage to balance power and simplicity as well as Fitness Logbook. Designed for everyone from beginners to professional athletes, this all-in-one training app—available for iOS and Android—helps you take full control of your workouts, recovery, and progress.

The app’s iOS version pairs seamlessly with Apple Watch, letting users track workouts, monitor heart rate, and log performance directly from their wrist. Whether you’re lifting weights, running circuits, or performing HIIT, Fitness Logbook ensures every move is recorded with precision.

With its intuitive workout interface, logging sessions feels effortless. The app’s advanced routine planner allows you to craft personalized programs or follow long-term training plans with built-in phases—ideal for structured strength, hypertrophy, or endurance training.

Versatility is at the app’s core. You can build and perform circuit-style workouts like EMOM, Tabata, AMRAP, or “for time”, choose from hundreds of exercises, or create your own custom ones. It even supports supersets, warm-up and failure indicators, and detailed set customization with RPE/RIR, tempo, and intensification methods such as drop sets, rest-pause, negative reps, and partial reps.

The built-in metronome and adjustable rest timers help maintain perfect pacing, while tools like the 1RM calculator, body fat estimator, and progress graphs turn your data into meaningful insight.

But Fitness Logbook goes beyond just tracking workouts—it offers a holistic approach to fitness. You can monitor macronutrient and supplement intake, keep tabs on sleep quality, and track body measurements to connect training with overall well-being.

With its combination of smart technology, clean design, and in-depth analytics, Fitness Logbook makes it easier than ever to train with purpose. Every rep, every meal, every hour of rest—it all counts, and this app makes sure you see the results.
