ISO Tracker vs The Bodybuilding Usage & Stats

The ISO-tracker™ app allows the user to seamlessly connect to the Bluetooth device (iso-tracker.com) to see in real-time: Their current force output. The max force output reached. The average force exerted during the session. (You can choose from two different modes with a tap of the Average button. The default setting tracks the average force over the course of the hold time. Swap to Average+ to have the app count reps, instead.) Also, auditory feedback lets you know when you've reached your set target force, as well as when you've reached the target hold time/reps. The app will read in Lbs, as well as Kgs.
