NeroKwik attempts to solve the problem of your images being spread across too many devices and networks, and for the most part it succeeds. Creating a single, easy-to-navigate interface for all of your photos across your iOS devices, Facebook, and Google+, NeroKwik works well, but not without some issues.
NeroKwik is designed to make it easy to access all of your photos on one device. It does this by adding every photo on each device you install the app on to an online account. You can also connect Facebook and Google+ to the same accounts so you can easily view all of the images from there, as well. When it is done syncing all of your accounts and devices, you will see every image from across all of them on one interface, from which you can bookmark, share, rate, and even to some degree edit those images. The interface is at times slow or lacking in direction, but overall the effect is well constructed and the feature set is immense when compared to other photo aggregation tools.
If you want a single interface from which to view all of your photos at once, consider NeroKwik. This easy-to-use iOS app will combine all of your accounts, and provide just enough tools to make it a good alternative to other free photo aggregation tools.
