How the app works, and how it was built.
A plain-language look inside Max Photo Frames: what happens between choosing a photo and saving it, the on-device AI that separates your subject, how layers and depth are put together, and why the file you save matches what you saw.
The journey
The mission, principles and progress behind building an exceptional free photo-frame app.
How it works

On-device AI
Cutting out a subject on your iPhone, without uploading the photo anywhere.
Layers and depth
How words go behind a person, and how a subject breaks out of the frame.

Why the saved file matches the canvas you reviewed, at delivery resolution.
Built and tested
The business analysis case study: 5,777 commits, 3,074 tests, and how every feature traces to one.
Backup & Sync
How your presets travel between devices, and why the app has no server.
Written for the curious, not only for engineers.
Each page starts with what you would notice as a person using the app, then explains the mechanism underneath. Industry terms appear only where they are the actual name for something, and the deeper detail waits behind a Show button on each page, so you only open what you want.
