Latest update crashes with iOS 18

App keeps crashing on iOS 18. Delete and reinstall doesn’t help either

Great In-Set Interface

Love it during the set. It’s not as intuitive looking back at information.

What I need for 5 starts (please make this happen!!!)
1. I need ability to input pounds and not kilos when it asks what weight I’m lifting (dumb American here)

What I’d love to be able to do:
1. See all the graphs (velocity/force/work/power/bar path) more easily when reviewing results
2. If I use a tablet/laptop witha bigger screen can I see all those meters at the same

App crashes frequently

I’m sick of the app crashing in the middle of a workout. I lose my stats/progress and have to restart the workout. Sort the app out ASAP!
Consider including an option to continue favourite workouts that have not been completed.

Awesome!!!

Great technical support. Easy to use and a great tool to help train athletes or yourself. Would highly recommend for anyone serious about training.

Great device!

Such a cool app!! Really easy to use and I really like how it displays bar path.

Happy buyer

The unit shipped quick enough and after a bit of playing around I figured out how I like to use the app best. My workouts are far better compared to not having Flex. Can’t imagine going back to training without it.

Great app, great device

Great training feedback and helps get the most out of sessions. So easy to use. Even has a social function so I my friends can see my sessions and comment.
