As headline says, Runna gave me various problems from shin splints to a runners knee. So I built a Runna but with less injury risk and more strength training. App is functional and integrates with Polar Flow (currently no support for other sport watches). Are you using Polar and want to try it? I’ll DM you the link. Looking for max 10 test users at this stage. If this ever comes an actual business, you can have free lifetime access in return for helping me. ✌️   submitted by   /u/No_Appearance_3038 [link]   [comments]
