I think you are struggling with sensory overload. The only two things I am concerned with is time and distance and both of those can be read from a cheap wireless bike computer. It doesn't enter it into your phone or computer automatically. I'm sure that any app that is based upon change in location (like riding down the road) is not going to work on your indoor trainer. You can get a cheap wireless computer from Chinese vendors for $5 postpaid. I have used the Sunding brand computer on my recumbent trike. It is accurate as long as you enter the right data in it for the circumference of the wheel. I measured it precisely using a run out where you measure the distance on the ground equal to each revolution of the wheel.
