Fossify Gallery
★★★★☆
A basic on-device gallery app that lets you view, browse, organize and delete your photos entirely on your own phone, and open them in other apps for sharing. No tracking, no ads. Works as a file picker too, when you’re already in another app and want to load a photo. Mostly replaces the offline use cases for Google Photos.
There’s a simple editor for cropping, rotating, markup and a few pre-defined filters. (IIRC the Simple Gallery app it was forked from had a few more adjustments it could do, but the Fossify project had some concerns about the license.) I’d like to use it to crop photos for iNaturalist, but there’s currently a bug where it loses EXIF data when editing. Even when I want to remove GPS coordinates, I don’t want to remove the time the photo was taken!
Update: There’s a similar bug where it discards location when used as a file picker, which has tripped me up a few times. Sharing from the gallery app keeps the metadata intact, though.
Anyway, if you do want to sync your photos with a cloud service, you can use another app for syncing while still using this one locally. I’m currently uploading to Nextcloud, and planning to try Immich when I can set aside some time to set up an Immich server.
