Welcome to ScriptBuilder! ScriptBuilder was made to capture and build screenplay ideas on the go. Before you face the dreaded blank page, build up your screenplay idea with ScriptBuilder! Features: • The Idea section helps you clarify your movie idea by answering specific questions, getting to the heart of your story • Structure your story arc with Act 1, Act 2, and Act 3 builders. All three act sections contain Act Beat questions to facilitate new ideas and notes which will prepare you when you're ready to build scenes • The "Character Builder" feature prompts you to answer questions about your characters to help you get to know your characters better and to discover their arcs. 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. That said, the two scores are not equally well evidenced: Writer Assistant (Wassi) has 80 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 36% of ScriptBuilder's written reviews are positive against 72% of Writer Assistant (Wassi)'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ScriptBuilder ships an update every 2 weeks, Writer Assistant (Wassi) monthly. The most recent releases landed on September 29, 2026 and September 30, 2026 respectively.
