Comments about Mobile Observatory 2 - Astrono Android Version

I mostly love the app, but a) the directional accuracy is horrible. Off by 6-20 degrees every time . I always use a Samsung Galaxy Note phone, and other compass-oriented apps have an average 4 degree +/- deviation and b) live view switches constantly, randomly, and seemingly without prompt to sky view. There are other little things, but those two are extremely disruptive, especially for being tools meant to enhance an activity where you should spend most of your time observing the sky instead of ***ing around with a recalcitrant app.
I, too, don't like to rent software that is crippled by subscription fees. I bought this app with the understanding that updates would have been included, not that I'd have to buy the app again and again whenever the developer chooses to name it something else. So, instead of buying the "pro" version, I'll be uninstalling it. I just invested my money into Star Walk 2 which requires no additional subscription fees to get all of its features.
Trying to not be critical of the publisher's chosen update path, this version 2 paid app has been good to me. I don't use it on a regular basis so the price seemed a bit steep for a mobile app but I bit the bullet, however I can't see myself doing the same again for a version that only had an updated database of objects more or less. The nag screen can be disabled but should have never been an update to the former paid version to my mind.
