Nav app in good direction

This app is somewhat ok. The map is reasonable but is missing many parks and significant locations. Navigation is fairly well calculated (only if on the right setting for a type of route, however, the better Navs seem to calculate the best route regardless of this setting) and its voice guidance is okay. I especially like that this app tells you well in advance which side your destination is on so you can plan where to park by the time you arrive.
This app does needs some serious optimization (the map and other functions lag quite a bit and this is on the latest 6s plus) but I imagine that is coming once the upcoming features are fully completed. Also, this app burns through the battery more than twice as fast as any other Nav app and makes my phone heat up significantly.
I am fine with the gas stations showing on the progress bar on the right because they dont effect the map itself but the user should be able to select which POI displays or none at all.
The one thing that will keep me from purchasing further is the subscription model. Like many, I dont like ongoing subscriptions. I much prefer a fair one time fee. Hard to say though which pricing model will be best; a higher one time fee or a lower ongoing subscription fee. I would bet many will lean away from the subscription fee.
