# ScriptBuilder vs Writer Assistant (Wassi)

The clearest difference is rating: ScriptBuilder at 4.6 against Writer Assistant (Wassi)'s 3.9. ScriptBuilder also leads on update cadence (every 2 weeks vs monthly). Writer Assistant (Wassi)'s advantage is review sentiment (72% vs 36%) and ratings volume (80 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ScriptBuilder sells 6 in-app purchases, starting at $5.99 per month and Writer Assistant (Wassi) sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

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.
