Best investment ever

I waited in great anticipation for my bike once I placed the order. And I can tell you it has been the best piece of exercise equipment I’ve ever owned. I’ve been working out at home and I’m gyms for most of my life time and this bike is amazing.
It’s smooth and quiet. It’s sturdy even when I stand to pedal. And the app tracks all my activity so accurately. It’s easy to use and fun to watch while you ride.
The app also makes me work harder because I can see where I need to be. It allows me to compete with myself.
And the app immediately hooked up with my bike and the heart monitor.
I just can’t say enough good things about the app and the bike ,

Works as expected as long as you end the session in time

At the end of each ride, after the M3i’s LED screen loses power, the app will prompt me to end the session. If I don’t confirm it in time (several seconds), the whole session’s data gets lost. Why is there a timeout for confirming end of session? And why deleting all captured data? I also found that if I leave the app running without confirming end of session, eventually it goes to a bad state in which it only shows the time is ticking but all the other meters show zero. There is no way to get out of that state except for forcing the app to close from IOS. I noticed the latest version is 1 year old. It’s time to get an update. By the way, can we have an Apple Watch version of this?

Provides FTP, Guided Sessions, Ride Data

The ability to take an FTP test periodically helps gauge progress. The guided sessions that are tailored to your FTP results are great! The app is a little glitchy though and sometimes has trouble starting up or pauses mid ride. If you open another app, your final data will tracked will be influenced by the time period you ran this app in the background, which is annoying. My biggest gripe though is with the calorie count. Since they have incorporated the Polar heart rate monitor readings in the app and have details from the rider profile, you wouldn’t think it would be too difficult to get accurate calorie counts. It is unclear what if any rider specific data is taken into consideration in the calorie count. Please address this. I wore my Suunto today out of curiosity and there was quite a disparity!!
