Geohash Droid is an implementation of Randall Munroe's (of XKCD fame) Geohashing algorithm, with wiki support.
Please report issues at the website.
New in version 0.7.19:
- Should have the file upload issue with KitKat solved. This DOES require the external storage permission now (it was tolerated until KitKat for legacy reasons, now it's required)
- File uploading will also do a quick check to see if you already uploaded the selected image so it won't waste time and bandwidth doing it again. It will still make another gallery entry for it.
