# Reality OBJ vs ShapeScript Mobile

The clearest difference is rating: ShapeScript Mobile at 5.0 against Reality OBJ's 4.2. ShapeScript Mobile also leads on iOS requirement (14.0 vs 17.0). Reality OBJ's advantage is update cadence (weekly vs fortnightly). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Reality OBJ sells 4 in-app purchases, starting at $2.99 per 7 days and ShapeScript Mobile sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ShapeScript Mobile holds the better App Store score, 5.0 against 4.2. Both are backed by a comparable volume of ratings — 5 and 4 respectively. Written reviews complicate that: 71% of Reality OBJ's written reviews are positive against 67% of ShapeScript Mobile's, so the app with the better star average is not the one people write more warmly about.

Reality OBJ ships an update weekly, ShapeScript Mobile fortnightly. Both last shipped on October 24, 2026.
