The iPhone 6 comes out in two days (and the much-debated Apple Watch launches early next year). Best of all, they’re all free, so download all you like! Makeup Genius As fun as it is useful, L’Oréal’s makeover app allows you to see how you look in certain products or pre-set looks. Scan a beauty product’s barcode, and Think Dirty will identify any ingredients that may be hazardous to your health. Input your personal beauty products, and the app will keep track of when you’ll run out — plus, it’ll let you know when the items you love are on sale.
