# Shor's algorithm vs FOLC

The clearest difference is in-app purchases: FOLC at none against Shor's algorithm's 3. FOLC also leads on device support (4 vs 2). On price, update cadence, ads and iOS requirement there is nothing between them.

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

Shor's algorithm ships an update every 6 months, FOLC every 4 months. The most recent releases landed on October 10, 2026 and October 4, 2026 respectively.
