# Vector Field vs Quantum

The clearest difference is in-app purchases: Vector Field at none against Quantum's 6. Vector Field also leads on device support (4 vs 2) and iOS requirement (15.0 vs 26.0). Quantum's advantage is rating (4.8 vs 4.5) and ratings volume (151 vs 6). On price and ads there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. Vector Field asks for nothing beyond the download.

Quantum holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Quantum has 151 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 73% of Vector Field's written reviews are positive against 81% of Quantum's.

Vector Field ships an update every 3 months, Quantum every 5 weeks. Both last shipped on October 30, 2026.
