Update is a disaster

Recent update causes the average force to peak out at a constant low value every third rep! The sound also no longer works. Several other reps then peak out at a constant high value. Set after set all the same!! Also the XL disc is incorrectly set at 0.075 when it should be 0.07!! Dismal quality control.

Latest update messed it up

Worked great until recent update. Now the inertia settings don’t line up with the plates you select

Love this!!!

I have the KBox3 and this app definitely feels like it completes the total usage of the equipment! Hearing power output go change motivates myself and my athletes to push harder and harder. Great job Exxentric!!!
