Best workout app so far...

I’ve been using this app since 2016, never a problem, and I don’t think I ever will experience a problem with this app. This app allows you to do workouts and check your heart rate. The computerized trainer is called Bonnie. Thanks, Cardio!
Incompatible with IPhone 11 Pro and 11 Max

This app uses the wrong camera on the backside of the 11 Pro and 11 Max. Those models have _3_ cameras on the backside. The one that Cardio uses is the camera furthest from the camera light- the wrong one- at least an inch away! At that distance no pulse signal is picked up through a finger, only noise. Multiple emails to developer; just get an automated reply back. No one is home. Until it is fixed, Cardio will not work in an iPhone 11 Pro or iPhone 11 Max.
Does not work well with iPhone 11 Pro

Loved the App on earlier iPhones. Now with multiple cameras on the iPhone 11 Pro, all you get are “poor signal quality” messages.
Useless since iPhone Upgrade

I used to love this app. Then I got an iPhone 11 Max Pro. It’s impossible to get a reading anymore. The app wants me to cover both cameras and the flash with one finger which is not even close to possible. It will start to read, then say it has a poor signal. Complete waste of money. Buyer beware, if you have an iPhone 11, don’t bother.
Heart rate monitor: worthless. 7 minute workout: 5 stars

The heart rate monitor works maybe 10% of the time. I use this app for the 7 minute workout which is short but really intense if you modify some of the exercises. For example instead of jumping jacks, do star jumps. Instead of step ups, do box jumps. Instead of tricep dips on a chair, do real dips between 2 chairs. Instead of lunges, do jumping lunges. I usually do two, seven minute workouts in about 20 minutes. It’s a great high intensity workout.
