SheInside is a shopping website that has a really cool feature. You act as a fashion designer and vote the articles of clothing you want to be created. Leave comments about the styles and you may be able to get their pre-sale items for FREE! You'll also get 50% off of pre-sale clothing but there's limited quantity and the price goes up the more it's sold. And you can always shop the regular collections at the normal price!
A few years ago I started using the TimeHop app and till this day it's one of my favorites. Connect it to your social media accounts and each day it will send you an update of what you posted on that very day 2, 3, 4, or 5 years ago. It's crazy to see what you were thinking or doing on that very day. It's also a great way to find some awesome #TBT photos you forgot existed! Download for Apple and Android.
