Used to be great, now worthless

This used to be my goto app for getting the hyperlocal distance, but recently I discovered that it no longer works correctly. I cannot click/select any of the various options, so the app is now totally worthless. I do not know that the cause of this is, but I would love to see it fixed (and updated for high resolution cameras like the Nikon D810).
