Beauty Stuff keeps track of when your cosmetics expire.

Two dates matter for a beauty product, and they are not the same. There is the expiration date printed on the box, and there is the period after opening — the little open-jar symbol with 6M or 12M on it, which starts counting the day you unseal the package. Beauty Stuff keeps both and tells you which one runs out first.

QUESTIONS IT ANSWERS
• Is this mascara still good, or was it opened last winter?
• When did I start this foundation?
• What does the 12M on the jar actually mean?
• Which of the things on my shelf have already expired?
• Do I own this already, or am I about to buy a second one?
• How much did I spend on skincare this year, and how much of it went in the bin unused?

WHAT GOES IN THE BAG
Primers, foundation, concealer, powder, blush and highlighter, eyes and lips. Cleansers, toners, serums, moisturisers, exfoliants, eye creams, masks and sun protection. Shampoo, conditioner and hair treatments. Body lotion, scrubs, hands and feet. Nail polish and perfume. The categories are already there and nested, so nothing has to be sorted out by hand.

WHAT STAYS THE SAME
No ads, ever. The bag lives on your phone and the app works offline; an account and syncing are yours to switch on. Photos and product lists are sent to a server only for the AI features, only after you agree to it, and you can turn that off in Settings. Your notes are never sent anywhere.
