## What is Inbox4?

Inbox4 turns your phone into a 4-cut photo booth.

• Live background swap — the camera removes your background in real time and drops you onto any scene.
• Famous landmark backgrounds — Eiffel Tower, Taj Mahal, Santorini, Mount Fuji and more.
• Gradient backgrounds and life-4-cut style frames.
• Upload your own custom backgrounds — keep as many as you like.
• Front or back camera, real shutter effect, 3-2-1 countdown.
• Save the finished strip to your Photos instantly — no QR codes.

Shoot, frame, save. That's it.
