Does FlipaClip work offline?

Animating with FlipaClip can be done offline with no problems. Since your projects are stored on your device, you will be able to access and update current projects, create new projects, and make movies. 

Because you will be working offline you will not be able to complete any actions that require internet access to another service (i.e. import images, audio, and video from third party cloud storage services or upload videos to social media sites.)
