Track every change, witness progress over time. Compare photos side by side and share instantly via AirDrop, WeChat & more.

Comparison Camera — Take before & after photos, generate comparison images in one tap.

Record progress at the same angle for fitness, growth, skin care, plants, or anything you want to track. View every shot on a timeline, compare any two with side-by-side, slider, or overlay modes, then save the comparison image to your photo library or share it.

Why Comparison Camera?

・ Built for before/after Organize by projects (e.g. "90-day cut", "succulent log"). Each photo lands on a timeline so you can pick any two and compare.

・ Align shots easily The first photo appears as a semi-transparent overlay in the viewfinder so you can match angle and framing for consistent, comparable shots.

・ Compare your way Side-by-side, slider, or overlay — see even small changes clearly. Generate a comparison image and save or share.

・ Your data stays on your device All photos and records are stored locally. Nothing is uploaded or collected.

Who is it for?

Fitness and weight loss, baby milestones, plant diaries, skin and hair progress, crafts and creations, pet growth — any journey where you want to see change over time.
