According to a German person on the Google Play store, my app deserves 1 star because it requests GPS permissions and has “giant ads”. Well, the GPS permissions were unnecessary and have been removed, but I don’t think the ads are particularly giant so they’re staying just the way they are. I considered leaving in the GPS permissions to show really huge ads to people in Germany, but that would have required work.
I also fixed an issue with the image gallery where Android 3.0+ devices weren’t able to see the saved images. They existed, but they just weren’t visible in the gallery. The problem probably exists on other devices, but the fix was more complex.
