# Vaia vs Nerdmask

Vaia and Nerdmask both sit at 4.7 stars, but that hides the real split: 81% of Vaia's written reviews are positive against 29% of Nerdmask's. Vaia also leads on ratings volume (1.6K vs 199). Nerdmask's advantage is update cadence (every 3 days vs weekly) and iOS requirement (15.1 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Vaia sells 10 in-app purchases, starting at $2.99 per month and Nerdmask sells 6 in-app purchases, starting at $8.99 per 7 days. 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 Vaia against 4.7 for Nerdmask. That said, the two scores are not equally well evidenced: Vaia has 1.6K ratings behind it against 199, so its average is the more settled of the two. Written reviews are what separate them: 81% of Vaia's written reviews are positive against 29% of Nerdmask's.

Vaia ships an update weekly, Nerdmask every 3 days. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
