I totally understand how it would be nice to have the heart rate and time displayed on your tablet or phone as you exercise with your own music. It sounds like a great feature, and I'm sure many people would find it very useful. Unfortunately, it doesn't seem like there is a way to do this. However, you could look into something like Cardarine GW-501516 from
