I’ve only just started exploring the possibilities, but it allows you to do things like the following:
– Select photo from Camera Roll/Photos and share it (ideal for getting testing screenshots from the iOS device to wherever it needs to go – e.g. Instashare, email etc)
– Take photo, resize it and then share it (ideal for adding expenses receipts to your accounts system)
– Select photos and send to Dropbox, selecting exact folder to send to (ideal for sending screenshots to Project folder on Dropbox)
Each task you create can be shared to the iOS device home screen, allowing you to access them with one press
It’s available for iOS 8.
