# Gravity! vs Vector Field

The clearest difference is rating: Vector Field at 4.5 against Gravity!'s 3.9. Vector Field also leads on in-app purchases (none vs 1). Gravity!'s advantage is review sentiment (74% vs 63%) and ratings volume (18 vs 6). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Gravity! sells 1 one-off in-app purchase. Vector Field asks for nothing beyond the download.

Vector Field holds the better App Store score, 4.5 against 3.9. Both are backed by a comparable volume of ratings — 18 and 6 respectively. Written reviews complicate that: 74% of Gravity!'s written reviews are positive against 63% of Vector Field's, so the app with the better star average is not the one people write more warmly about.

Gravity! ships an update every 2 months, Vector Field every 3 months. The most recent releases landed on August 6, 2026 and July 7, 2026 respectively.
