Scriptonite

The Scriptonite app helps you startup and grow stories on the move. Simply start anywhere and develop beat by beat, scene by scene. No more worry about pages, the story is all here.
No more forgetting ideas or creating useless notes. This app help turns narrative guesswork into workflow with a visual storytelling environment that recycles mistakes into solutions.
Dynamic story mapping is ideal for non-writers too, as practical and collaborative design tool.
Scriptonite (0.8 version) is basic: no photo images, video or public sharing yet. Users, though, can make 5+ characters and save 3 stories locally. Audio input is for now active via keyboard and only in Scene View. 
Support, tutorials and live support are available on the website.
