# Algorithms HQ vs CLRS.Helper

The clearest difference is price: Algorithms HQ at Free against CLRS.Helper's $0.99. Algorithms HQ also leads on review sentiment (100% vs 67%). CLRS.Helper's advantage is rating (5.0 vs 4.0) and update cadence (every 6 weeks vs every 16 months). On ratings volume, ads, in-app purchases and iOS requirement there is nothing between them.

Algorithms HQ is free to download; CLRS.Helper costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

CLRS.Helper holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 100% of Algorithms HQ's written reviews are positive against 67% of CLRS.Helper's, so the app with the better star average is not the one people write more warmly about.

Algorithms HQ ships an update every 16 months, CLRS.Helper every 6 weeks. The most recent releases landed on September 24, 2026 and October 6, 2026 respectively.
