Hellow! is a free photo-sharing app for iOS that in practice is somewhat similar to Snapchat, but still clearly serves a different purpose. Photos don’t disappear until you manually delete them, and the ability to schedule when and where to send them means planning a thoughtful picture to share ahead of time is far more plausible. These additional features for photo management make it less geared for casual use and more toward meaningful use. Hellow! works on all iOS devices using iOS 7.0 or above.
