Great app for solving mystery geocaches. But one thing annoys me so much. The dropdown menus under the tools are just completely white and I have to scroll and then click the next "button" in order to change e.g. the value or the rotation factor.

Sorry to hear the dev had to pull the donate link. 😟 Went to the app/dev's website and saw there's a 'pro' version, which I plan to purchase, to show support. Unfortunately, the Play Store/Market link didn't bring up anything. I'm guessing it was also dropped for having a donate link. I'll check back later to see if it's back.

I love geocaching but I've always struggled with mystery caches. Sometimes I have an idea what may be required but most of the time I don't. I thought this app might help me solve mystery caches, but having spent an afternoon looking again at dozens of mystery caches near me I am none the wiser. The problem is: how do I apply the tools provided in the app to the puzzle if I don't know what the puzzle requires to solve it? Having read all the positive reviews I now also feel very stupid.
