Google launched the stand-alone Photos app with unlimited storage in May. Now it has announced it will be phasing out its predecessor Google+ Photos. On August 1, the Google+ Photos Android app will stop working and soon afterwards the iOS and web versions will cease to be operational as well. 

If you are a current Google+ Photos user you can access all your images and videos simply by installing the new app on your device. Files will also be accessible via http://photos.google.com on the web, or you can download your image archive via the Google Takeout service. 

Now appears to be the time to switch. Apart from free unlimited storage of high resolution images and video, Google Photos also offers automatic backups as well as organization and presentation tools.
