# Fluid card vs Algbra

The clearest difference is rating: Algbra at 5.0 against Fluid card's 4.6. Fluid card's advantage is update cadence (weekly vs every 2 weeks). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Algbra holds the better App Store score, 5.0 against 4.6. Both are backed by a comparable volume of ratings — 21 and 20 respectively. Written reviews complicate that: 60% of Fluid card's written reviews are positive against 55% of Algbra's, so the app with the better star average is not the one people write more warmly about.

Fluid card ships an update weekly, Algbra every 2 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
