My Makeup Collection a makeup inventory app for recording, reviewing and organising makeup items and swatches and sharing your makeup looks. It also allows users to create and share wishlists by email, Facebook or twitter. It is available in iOS and Android.
By recording their current makeup items on their phone users can remember what they want to buy at the store, and compare any new testers with pictures of the product they already own. This reduces the amount of "dupes" (similar products) they purchase.
The app also has an analytics function summarising how many of each makeup type and brand the user have, which allows them to streamline and plan future purchases.
