You issue is that you only want a tailor made app for only what you wish to see. It's too easy to do more in the apps with the data they get, so they do.


The screens on both the apps and the actual GPS devices can usually be configured to show only what you want to see.

Does the Strava App or RideWithGPS app not connect to your strap? A long time ago, I use to use OruxMaps on my smartphone. It did everything. Including connecting to HR sensors. So you probably wouldn't like it gives you more than you want.

Although with any, you usually don't have to use the stuff you don't want.

I'd only use the Apps from the bigger and better known players. Too many apps won't work unless you give them permission to virtually everything on your phone. So you need to trust that they aren't aggregating data from you and others to sell. Particularly when it's a free app. Which puts most people in the position to want to give away all those permissions for free.
