# Algorithms HQ vs Algorithm Visualizer

The clearest difference is rating: Algorithm Visualizer at 5.0 against Algorithms HQ's 4.0. Algorithm Visualizer also leads on update cadence (every 9 days vs every 16 months) and ratings volume (4 vs 1). Algorithms HQ's advantage is in-app purchases (none vs 3). On price, review sentiment, ads and iOS requirement there is nothing between them.

Both are free to download. Algorithm Visualizer sells 3 one-off in-app purchases. Algorithms HQ asks for nothing beyond the download.

Algorithm Visualizer holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

Algorithms HQ ships an update every 16 months, Algorithm Visualizer every 9 days. The most recent releases landed on September 8, 2026 and June 4, 2026 respectively.
