About HIIT 4x4 Lite
The HIIT 4x4 intervals are as follows:
- 10 minutes warmup at 60% MHR
- 4 minutes high intensity at 90% MHR
- 3 minutes low intensity at 70% MHR
- repeat high-low intervals 4 times (4 high intensity intervals of 4 minutes each = 4x4).
HIIT 4x4 Lite uses a speedometer type dial to display heart rate. When the arrow is in the green zone then your heart rate is within the interval target. If the heart rate later falls out of the target range, warning chimes are issued until back in range.
Each person's MHR is different, and changes with age. A commonly used formula for MHR is 220 - age in years. A more accurate number can be discovered by using a heart monitor during all out exercise and observing the highest heart rate achieved.
HIIT 4x4 Lite does NOT store your workout history using Apple Health. Please use the full version HIIT 4x4 (not Lite) to store workout history.
HIIT 4x4 Lite is based on the High Intensity Interval Training 4x4 program developed by the Norwegian University of Science and Technology's Cardiac Exercise Group.

What does the paid version do?
What are the limitations to the Lite version that the paid version can do? For me this version does not stop after 4 intervals.
Great but crashes
Simple, works great, finally a Norwegian 4 app!
This app is great. It is easy to use , the explanations are very detailed, it works flawlessly. Turn it on and it will give you your max heart rate. It has a timer for when you 4 minutes are done and the beeps plus dial on colors really help a lot when you are exercising hard and you can’t fumble with your watch. If you’re into HIIT, this is the one for you. I’ve been doing HIIT for years and I finally found an app. that’s easy and efficient. Even took the time to review it and I rarely review apps, shows you how much I like it.
