# ScriptBuilder vs ButterDocs

The clearest difference is review sentiment: ButterDocs at 100% against ScriptBuilder's 36%. ButterDocs also leads on in-app purchases (none vs 6). ScriptBuilder's advantage is rating (4.6 vs 4.0) and update cadence (every 2 weeks vs every 3 months). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. ScriptBuilder sells 6 in-app purchases, starting at $5.99 per month. ButterDocs asks for nothing beyond the download.

ScriptBuilder holds the better App Store score, 4.6 against 4.0. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 36% of ScriptBuilder's written reviews are positive against 100% of ButterDocs's, so the app with the better star average is not the one people write more warmly about.
