What is WorkoutStack?

WorkoutStack is a gym workout tracker and logger built on three core principles: bold, colourful design, blazing-fast local data, and rich stats. It was inspired by feedback from an interval training app used by over 3 million people globally. No account is needed to use the app, and it works entirely offline—so you never have to worry about losing signal in a basement gym. With over 2,900 exercises and a custom stats dashboard, WorkoutStack helps you log sets fast and measure your progress with clarity.

Who it's for

• Lifters who hate complicated apps – WorkoutStack strips away unnecessary complexity, giving you a focused, colour-coded workout view that stays clean as you complete sets.
• Gym-goers with no signal – The app works fully offline with no account required, so you can log workouts anywhere, even in dead zones.
• Data-driven athletes – Build a custom stats dashboard to track your progress, including a 1RM calculator, so you can see exactly how your body is improving over time.

Key features

Bold, colour-coded exercise logging

Exercises are displayed with bold colours that tuck away as you complete them, keeping your workout view clean and distraction-free. This design makes it easy to scan your session at a glance and stay in the zone.

2,900+ exercises with posture videos

Every exercise comes with a posture video to ensure perfect form on every lift. You can filter the library by target muscles or equipment, so finding the right movement for your routine is quick and intuitive.

Works offline with no account needed

All your data lives locally on your device, meaning zero loading times and no reliance on internet connectivity. You can start logging immediately without signing up or logging in.

Custom stats dashboard

Build your own stats dashboard to track key metrics like your one-rep max, volume, and progress over time. This gives you a clear, visual picture of your strength gains without digging through spreadsheets.

What stands out

"Logging a workout should feel as good as lifting."

WorkoutStack turns the chore of logging sets into a satisfying, visually engaging experience. The combination of bold design, instant local data, and offline reliability means you spend less time tapping and more time lifting—while still getting rich insights into your progress.
