Easily add in your different shifts then assign them to days on the simple Calendar screen.
ShiftBuster is an iOS app that allows you to share your shift pattern with your friends. You can enter a fixed shift pattern and the app will work out your schedule for the year. Exchange the data with friends using Facebook, and see who's on, and who's off using a simple calendar view or overlay 2 friends' shifts on top of yours. ShiftBuster is flexible so you can share just with your partner, or with 100 colleagues. It's up to you!
Requirements: Compatible with iPhone and iPod touch. Requires iOS 8.1 or later. WiFi, or mobile data sometimes required.
