Impossible to use
Age is fixed at 20 years and the app keeps disconnecting thus making it unable to do what was designed for.
Just what I was looking for
I spent a couple of weeks on and off looking for an app that would save me continuously checking my watch when trying to use my cross trainer. Silly as it sounds I’m using it for cardio so heart rate is important and constantly taking my hand off the machine to flick my wrist and wait for the heart rate to display was annoying. I looked in loads of places for a heart rate monitor that could be displayed permanently during my exercise period. Long story short this is a gem on a find. Syncs seamlessly with my Apple Watch, displays the heart rate and where I am on the cardio scale, which is set for my age group. Stays open while I’m using it so the checks are instant, even has a guess at the calories burnt ( needs to tweak that up a bit ;) All round exactly what I needed and I paid £1.99, I had been considering £100 for a decent chest strap and App.

Great for live HR monitoring.
Great app for monitoring heart rate live on full screen. Works well with Apple Watch. Need to sort out saving the heart rate zones to make it complete.
Bad Experience
Apple should not allow anyone to sell app without trial period. This app does not deliver what it promised. Useless.
Stupid app
