I had been happy to pay for Strava Premium for several years. Strava actually advertised the Wahoo TICKR BT HRM in their app feed and I bought it so I could also record my HR. HR and Beacon (to let others you authorize see where you are real time) justified the monthly fee. Then sometime last year Strava removed the BT HRM functionality from the app. This meant if I wanted Beacon I could not longer record HR. So dropped Premium and started using Wahoo app to record rides and upload them to Strava.

If Strava wanted me back as a paid user I would also want to be able to record HR thru BT devices on iPhone. It pissed me off they took that away after advertising the Wahoo HRM in their feed.
I may end up being OK with free, but it will be in the details.

For example can I analyze someone else ride so I can confirm it is legit? I think I spend almost as much time chasing the top 10 as I do flagging fakes.
