Google photos backs youe photos up automatically, and it’s the best option there is to have your memories stored but sometimes it acts strange like takes a lot of time to load and the worst thing is if you delete something from your phone it doesn’t delete it there and there isn’t an easy option to delete them from back-up either.
There’s good option for editing on the app itself, it’s pretty good I’d say but should be more customisable and have less control over the phone’s gallery.
