Flexify: Gym Workout Log

Log workouts, reps, cardio, and rest timers. Track strength offline.
Log your gym workouts, follow your strength progress, and keep your training private.

Flexify is a fast, offline workout tracker for strength training and cardio. Record sets, reps, and weights, use rest timers to stay on pace, and review clear progress graphs after every session.

BUILD A BETTER TRAINING LOG

• Log strength workouts, exercises, sets, reps, and weight
• Record cardio sessions and cardio types
• Use rest timers and alarms between sets
• Review workout history and strength progress with graphs
• Tailor features, settings, and light or dark appearance to your routine

PRIVATE, FAST, AND OFFLINE

Flexify does not require an account or internet connection. Your workout data stays on your device, so you can train and log sessions anywhere. The app is open source and has no advertising or tracking.

Whether you are beginning a gym routine or refining an established programme, Flexify gives you a focused workout journal without clutter.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
