# GridMaker vs Spatial Vis

The clearest difference is price: Spatial Vis at Free against GridMaker's $0.99. Spatial Vis also leads on in-app purchases (none vs 12) and update cadence (every 5 days vs every 3 months). GridMaker's advantage is review sentiment (52% vs 27%). On ratings volume, ads, device support and iOS requirement there is nothing between them.

Spatial Vis is free to download; GridMaker costs $0.99 up front. GridMaker sells 12 one-off in-app purchases. Spatial Vis asks for nothing beyond the download.

Spatial Vis holds the better App Store score, 3.4 against 3.2. Both are backed by a comparable volume of ratings — 41 and 18 respectively. Written reviews complicate that: 52% of GridMaker's written reviews are positive against 27% of Spatial Vis's, so the app with the better star average is not the one people write more warmly about.

GridMaker ships an update every 3 months, Spatial Vis every 5 days. The most recent releases landed on September 21, 2026 and September 8, 2026 respectively.
