Description says app will require a half dozen permissions including stuff like access to network, but after I installed it, the only permission it got is access to storage; good. If you don't know the word Exif, you might miss getting this app, which would be too bad. I learned screenshots have no Exif data. Phone photos have repetitive Exif data, but the exposure data can be interesting. My phone doesn't accept a memory card, so I won't be looking at Exif data of photos from other devices.

Lost GPS Resolution. Since the GPS coordinates are shown in deg, min ("), sec ('), you lose 3 bits of resolution in latitude and up to 3 bits in longitude compared with what a cell phone is capable of. In other words, 1 arc minute of latitude = 101 ft whereas my cellphone indicates 13 ft of resolution; that's a factor of 8 difference. The resolution lost in longitude is the same at the equator and is reduced as you go towards a pole. If they provide 3 more bits of resolution I'd use it.
