Questions

Which iPhone do I need?

Any iPhone with iOS 18 or later. RAW DNG needs an iPhone 12 Pro or a later Pro model (ProRAW). Apple Log stills need an iPhone 15 Pro or later. 48 MP needs an iPhone whose camera offers it. The app tells you when your iPhone cannot use a format.

Is my original photo kept?

Yes. The app always keeps the original next to the photo with the look.

Do I need an account?

No. There is no account, no cloud and no tracking. Everything stays on your iPhone.
