Hi,
Could someone recommend me an app for heart rate training in the gym with a non-smart static bike (it is an "Ergo-Fit Vitality System))? I have a bluetooth Mio heart monitor and would like to stay in a particular HR zone - and ideally the app wpould alert me if I need to slow down or speed up my effort etc.
It would be great as well if the app could help calculate HR zones and FTP. This particular static bike has power in watts but is not exactly a Wattbike :/
Thanks in advance!
