Getting to know your characters will make writing your scenes with these characters smoother. (Access through in-app purchase) • The "Scene Builder" feature provides useful questions that when answered help bring clarity to what the scene does to move your story and characters forward. (Access through in-app purchase) Unlimited Access: All Access (1 Month) $5.99 All Access (1 Year) $49.99 -------------------------------- I originally built this app because I found myself coming up with ideas for screenplays but didn't have a dedicated place to capture them. I also wanted a tool that would help me flesh out the story, characters, and scenes before I sat down in front of my computer to write. I want to continue to iterate on ScriptBuilder with new features to make it even better. If you have any feature requests, questions or comments, please go to the support url and send me an email :) I hope ScriptBuilder helps you along your path in creating compelling stories in both feature films and television. If it does help, please share ScriptBuilder with your family and friends. Thank you! -------------------------------- Privacy Policy: https://www.scriptbuilderapp.com/_files/ugd/b622d0_f5722cd213394590bbd181559a0af540.pdf Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

ScriptBuilder holds the better App Store score, 4.6 against 3.9.
