Suggestion
I love the cardio apps. One suggestion for updates would be, if possible, show the status on the lock screen while app is still active. I like to lock my phone while using it at the gym but sometimes forget the speed I should be going or I get distracted in the gym just as the trainer/app is switching to a new speed.
