About

This app tells you what to put on tonight: the steps in the right order, the products you own at the place you are, best first. It follows a few rules so you don't have to keep them in your head:

• Never two strong actives (retinoid, exfoliant) on the same night or back to back.
• The morning after a strong night, skip vitamin C and other morning actives.
• Seal every active with a moisturizer. Oil goes last.
• Sunscreen every morning, never skipped. Exfoliants stay home when you travel.
• Recovery turns every active off until you turn it back off; restart gentlest first.
• If an active isn't where you are, tonight becomes a gentler night, and the app says why.
• Your own ranking always beats the app's.

Not medical advice. This app organizes your products and their timing; it doesn't diagnose or prescribe. Ask a dermatologist about anything that hurts, burns or won't settle.

Your name, a scrambled copy of your PIN (never the PIN itself), your time zone, and your routine: your skin profile, places, steps and products. No email, no photos, no location tracking.

The site admin can reset a forgotten PIN and see account names, but never your routine. Deleting your account (on the Me page) deletes everything.

Product suggestions come from a short list kept by hand. Prices are approximate; check before you buy. Nobody pays to be on it.
