# iDesign vs Structure Graphing

The clearest difference is rating: Structure Graphing at 4.5 against iDesign's 2.6. Structure Graphing also leads on update cadence (weekly vs every 3 months). iDesign's advantage is review sentiment (50% vs 25%) and device support (3 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. iDesign sells 3 in-app purchases, starting at $6.99 per month and Structure Graphing sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Structure Graphing holds the better App Store score, 4.5 against 2.6. Both are backed by a comparable volume of ratings — 87 and 60 respectively. Written reviews complicate that: 50% of iDesign's written reviews are positive against 25% of Structure Graphing's, so the app with the better star average is not the one people write more warmly about.

iDesign ships an update every 3 months, Structure Graphing weekly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
