Vector Field lets you create and visualize mathematical vector fields with thousands of animated particles. Enter your own equations, adjust the simulation instantly, and watch how particles move through 2D, 3D, or spherical spaces. Whether you are studying differential equations, experimenting with dynamical systems, teaching vector calculus, or simply exploring mathematical patterns, Vector Field turns equations into interactive motion. Features: • Visualize vector fields in 2D, 3D, and on a sphere • Define custom dx, dy, and dz equations using x, y, z, and time t • Use built-in function presets or save your own • Adjust particle speed, density, lifetime, colors, and ranges • Animate time-dependent fields • Normalize vectors to focus on direction • Rotate 3D views interactively • Powered by Metal for smooth real-time rendering • Create, tweak, and discover vector fields directly from your device.

Verdict
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.
