Shoebox is unlimited free photo backup for all your devices. It automatically backup your photos to keep your memories safe, secure and private. Carry every photo you’ve ever taken in your pocket or on your tablet without taking up space on your phone or tablet. Which also remove the risk of  losing photos if you lose your phone or your hard drive crashes.
If you’re looking for the alternative to the Google+ cloud based photo hosting than Shoebox is the best one to try.  Not only can you install and use an Android app, but there’s also an iOS client and desktop (Mac and Windows) as well. You can log in from anywhere and check out your photos.
Additional features include social media sharing, unlimited slideshows, auto-backups, timelines, and most importantly it has the Google Chromecast Support which helps you to see the photos on the Big screen . All accounts come with a 30-day trial of the Pro plan which offers full, original resolution.
