Rethink ‘poor signal’ alert – Cardiio: Heart Rate Monitor Review

This app is very useful while taking a jog, for giving me an indication for when I need to take a break and when to restart. However, half of the readings end with the poor signal quality pop-up, which prevents saving of the result. By then my heart rate is too low to take another reading and save it.
