# Quantum Mechanics + vs Quantum

The clearest difference is update cadence: Quantum Mechanics + at daily against Quantum's every 5 weeks. Quantum Mechanics + also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 81%). Quantum's advantage is ratings volume (151 vs 4). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Quantum Mechanics + sells 1 one-off in-app purchase and Quantum sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Quantum Mechanics + against 4.8 for Quantum. That said, the two scores are not equally well evidenced: Quantum has 151 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 100% of Quantum Mechanics +'s written reviews are positive against 81% of Quantum's.

Quantum Mechanics + ships an update daily, Quantum every 5 weeks. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
