About

We built the diary we wished we’d had.

Glow Up Diary is a 90-day photo diary for iPhone. One minute a day, front, side and back, lined up, compared and cut into a film of how far you came.

Glow Up Diary welcome screen: See the change the mirror hides

Why it exists

Change is slow. You see yourself every day, so you never notice it, and the scale bounces around with water and salt. Most of us have a camera roll full of half-hearted progress pictures taken in different rooms, different light and different clothes. They’re impossible to compare, so we stop taking them.

Glow Up Diary is the organized version: one spot, one minute, every day, for ninety days. It lines your photos up, puts Day 1 next to today, marks the milestones and, once you have a week of photos, cuts them into a film. When the mirror says nothing has changed, the diary shows you what has.

Our guides

Alongside the app we publish practical guides on progress photos, skincare and body transformation. Every guide is researched from primary sources, cites them, and is updated when the evidence changes. Read how we work in our editorial policy, and please read our medical disclaimer: our guides are information, not medical advice.
