# Shor's algorithm vs MARVLS

The clearest difference is in-app purchases: MARVLS at none against Shor's algorithm's 3. MARVLS also leads on update cadence (every 4 weeks vs every 6 months). Shor's algorithm's advantage is iOS requirement (16.0 vs 18.0). On price, ads and device support there is nothing between them.

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

Shor's algorithm ships an update every 6 months, MARVLS every 4 weeks. The most recent releases landed on May 19, 2026 and September 9, 2026 respectively.
