# Algorithm Visualizer vs Shor's algorithm

The clearest difference is update cadence: Algorithm Visualizer at every 9 days against Shor's algorithm's every 6 months. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Algorithm Visualizer sells 3 one-off in-app purchases and Shor's algorithm sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Algorithm Visualizer ships an update every 9 days, Shor's algorithm every 6 months. The most recent releases landed on June 4, 2026 and May 19, 2026 respectively.
