Hey guys. First of all let me say thank you for the great app you are developing. Please put paypal donate button on ecoach site, so we could support developer(s) - we need him(them) now more than ever.

Second of all, let me give you feedback from dedicated mountain biker point of view and add my voice to previous feedbacks:
1. Audible signal when reaching at least max HR (ideally - when reaching aerobic/anaerobic/max HR) Not important feature: ability to use your own recorded ogg/mp3 files for that.
2. Calorie Calculator
3. Autopause(with ability to turn it off)

HeiaHeia guys, I know you monitor this thread too: thanks for the service! Do you plan to implement HR and speed graph on your website? I can see it in ecoach but heiaheia only displays average and max HR and map only, no graphs. And some additional logs other than weight log would be nice: like resting HR, blood pressure, waistline to monitor changes in the fitness.
