Scrambled EXIF
★★★★☆
Scrambled EXIF is one of those “does one thing really well” apps: It’s a filter that removes all the date, time, location, camera, and other metadata from a photo as you share it. Using it is incredibly simple: Share the photo to Scrambled Exif, and then it’ll ask you what app you want to share it to.
It’ll optionally fix EXIF-based rotations and rename your file too (in case you don’t want the filename to give anything away).
The only problem I have with it is that most of the time, I don’t want to remove everything. 99% of the time I want to keep the timestamp, and there are times (like posting observations to iNaturalist) when I want to keep the location too. So I don’t use it very often, though I do keep it on my phone for when I do.
But for its primary use case, it’s sheer elegance in its simplicity!
