# AlgoApp vs Vaia

AlgoApp and Vaia both sit at 4.7 stars, but that hides the real split: 81% of Vaia's written reviews are positive against 50% of AlgoApp's. AlgoApp's advantage is ratings volume (20K vs 1.6K) and device support (4 vs 2). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. AlgoApp sells 4 in-app purchases, starting at $9.99 per month and Vaia sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for AlgoApp against 4.7 for Vaia. That said, the two scores are not equally well evidenced: AlgoApp has 20K ratings behind it against 1.6K, so its average is the more settled of the two. Written reviews are what separate them: 50% of AlgoApp's written reviews are positive against 81% of Vaia's.

AlgoApp ships an update every 4 days, Vaia weekly. Both last shipped on November 11, 2026.
