Free to download · iOS · Your photos stay on your device
Most people can't tell if a product is working. Proof28 removes the guesswork with one simple daily habit.
Take guided front, left and right photos in under 60 seconds. A ghost overlay of your Day 1 photo keeps every angle consistent — so comparisons are fair.
Log your routine, products and lifestyle factors each day. Build your streak, hit milestones, and watch your 28-day journey fill in.
Run an AI comparison between any two days. At Day 28, get your full verdict: what changed, what improved, and what didn't.
No fake scores, no gimmicks — just the tools to see what your skincare is really doing.
Guided front, left and right capture with a ghost overlay that keeps every photo consistent, day after day.
Compare any two days and get a plain-English read on real, visible changes — redness, texture, clarity, tone and glow.
Point your camera at the back of a product — the AI reads every ingredient and tells you what each one's for.
A full verdict at the end of your cycle — export it as a PDF or share your Proof Card.
One tap and the AI compares your photos and reads your skin across six signals — redness, texture, clarity, tone, blemishes and glow — then writes you a plain-English verdict. No fake scores, no guessing.
Redness, texture, clarity, tone, blemishes and glow — compared between any two days of your journey.
It tells you what actually changed — and it's honest when it can't see a meaningful difference. Guidance only, never medical advice.
Point your camera at any skincare product — the AI reads every ingredient off the label, tells you what each one is for, and flags how it matches your skin goals.
Skincare is a £500+ a year habit for most people — and almost nobody knows which products are earning their spot.
Memory is a terrible before-and-after tool. Proof28 controls the angle and framing so Day 1 vs Day 28 is a fair, honest comparison.
Your daily photos stay on your device. Nothing is uploaded to our servers, sold, or shared — ever.
We don't invent a number to flatter you. The AI describes what it can actually see change — and tells you when it can't.

Build your shelf in seconds — scan its ingredients or add manually, and see what's active in your current cycle.
