I'm trying to determine what would be the best route to go for an app idea I have in regards to using a back-end service or not.
The app will not require any sign up / log in steps
The concept does have a part of taking a photo. For example, a photo could be taken every day, or multiple photos per day, equaling 365 + photos.
I'd like for the user to be able to view these photos at any time, and possibly export them all at once in some form (if that is possible) at any time.
What's the best way of doing this to have a good experience in the app?
