Real-Time Workout Guide:
Flex’s workout guide will lead you through your workout step by step, telling you which exercises to do, how to do them, how long to rest for optimal results and notifying you when you need to start your next set. You also have the spreadsheet view where you can fully modify your workout on the fly. Move around exercises, change exercises, add/remove sets. Control your music without leaving the app thanks to native Spotify and Apple Music integrations.

You can't improve what you don't measure. With Flex, you can track:

How consistently you’re exercising with the calendar feature
Your total calories burned daily, calculated from workouts/steps/BMR
Your bodyweight over time
Your steps with a 10k daily goal via the Apple Health integration
Your exercise progress with the exercise stats
Your workout history

An even easier way to workout with Flex Apple Watch:
Use the Flex apple watch app to log sets and complete workouts without needing to constantly check your phone. Sync your data and close your activity rings.

Simple And Easy

Full disclosure, I was lucky enough to be part of the beta testing. The app was great through the testing and was nearly flawless and rock solid.
It is easy to set-up, use and track progress. I tried a few others before but found them awkward. I like the ability to link in Apple and Spotify music as well to keep me motivated through my workouts.

Great workout/fitness app!

Was part of the testing. It has come a long way. There are a lot of good programs for everything and anything you want to work on. From overall fitness, fat burning, muscle building and strength.
Workouts and demos are pretty straight forward.
Tracking is good too. No longer need to keep a conventional notebook and pen with you. Just use the app and log your workouts. See your progress.

Keep up the great work!
