And, I paid for Polarr when it was single purchase, just before they went subscription-based, so that was definitely worth it.

I use Handy Photo and Retouch by ADVAsoft for removing some basic elements. Photo Editor is quite powerful and feature-rich, but since it's not my go-to it often takes me longer to find my way through all the menus than Snapseed, especially on the phone vs the Chromebook with the larger screen. I have a few different apps on my phone/Chromebook that I'll use for special purposes: Photo Editor (blue/white icon, by MacGuyver) especially for quickly resizing to a particular resolution/file size or adding text. It's usually my go-to, with enough editing options to be really useful without being too overwhelming.

If you're new to photo editing on Android, then I think Snapseed is a great place to start. Possibly there's some relevant workflow wisdom elsewhere on this site or elsewhere. All that occurs to me is either to use the star rating or tagging systems to keep them identified, or to save the edited batch to a separate folder and do the final file conversion from it. I can why you'd want to retain a selection from a folder of originals and individually edit then batch convert, though not something I've done. What I'm really looking for is the ability to load up all the images I want to edit in one go, carry out the edits on each one individually (but also be able to copy edits as well) and then at the end export them all in one go. I've used the MacGyver app and I'm a big fan but the batch editing is limited in that you have to do the same edit for each photo. I've been trying out lightweight, free Photo Editor (MacGyver) which is very cute and batch processes to PDF as well. Photo Mate R3 (paid app) does batch conversions to JPEG, PNG, TIFF - not sure if the trial version will. I contacted Polarr about this and they said it was possible but it's not, unless I'm doing it wrong. Does anyone know of an android app that allows bulk exporting of photos, like you can do with desktop apps?
