# Neutrons4Science vs Quantum

The clearest difference is rating: Quantum at 4.8 against Neutrons4Science's 4.0. Quantum also leads on update cadence (every 5 weeks vs every 8 months) and ratings volume (150 vs 1). Neutrons4Science's advantage is in-app purchases (none vs 6) and review sentiment (100% vs 81%). On price, ads and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. Neutrons4Science asks for nothing beyond the download.

Quantum holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Quantum has 150 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Neutrons4Science's written reviews are positive against 81% of Quantum's, so the app with the better star average is not the one people write more warmly about.

Neutrons4Science ships an update every 8 months, Quantum every 5 weeks. The most recent releases landed on October 9, 2026 and October 24, 2026 respectively.
