Android: You've got hundreds of photos you've collected over the years. You don't want to pore through the pile picking out the good ones. Slidepick helps you get rid of the junk with a simple feed using Tinder-like gestures to swipe away photos you don't want, and keep the ones you do.
The app plugs into your cloud storage (including Dropbox, Google Drive and Box), social networks (including Facebook and Twitter) and your phone's own storage. Swipe a photo to the right to add it to an album of photos you want to keep. Swipe left to exclude it. There are also buttons available to delete them if you want. The app makes it easy to sort through your photos during your downtime, rather than waiting until you can sit down at a computer.
To use the app, head to the company's site below and sign up to be a beta tester. You'll need to join a Google+ community and opt-in to the beta via the Play Store first. Then you'll be directed to download the app itself.
