# Shor's algorithm vs Resonant Quantum Mechanics

The clearest difference is in-app purchases: Resonant Quantum Mechanics at none against Shor's algorithm's 3. Resonant Quantum Mechanics also leads on update cadence (weekly vs every 6 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Shor's algorithm sells 3 one-off in-app purchases. Resonant Quantum Mechanics asks for nothing beyond the download.

Shor's algorithm ships an update every 6 months, Resonant Quantum Mechanics weekly. The most recent releases landed on October 27, 2026 and October 9, 2026 respectively.
