scrambled exif is really practical & easy to use. it has been a player for a while now where as metadata remover seems newer & possibly less trustworthy/vetted because of it.

it also doesnt seem to add much new functionality from scrambled exif besides viewing data in app.

I personally use image toolbox which allows you to select what specific exif tags you would like to remove. however, I wouldnt put any more trust in its accuracy or comprehensiveness than any other adjacent app as they realistically all probably work very similarly.

if its imperitive you don't leak any exif data I would recommend checking that in an external & more trusted app anyway. something like aves or a similar gallery that will lay out all all metadata tied to an image.

I just use inbuilt fossify gallery function. No need for another app.

I use scrambled, no complaints.

Image Toolbox

I like Image pipe. https://f-droid.org/packages/de.kaffeemitkoffein.imagepipe/

It's also tiny at 550k compared to imagetoolbox at 57mb

Yo can use the vgy.me image sharer, it removes also the exif data by default uploading images there.

Both are good, depending on your personal preferences one could fit your work flow better than the other. In terms of privacy I did not recognize any difference.
