# Vaia vs Eumathes

The clearest difference is ratings volume: Vaia at 1.5K against Eumathes's 1. Vaia also leads on update cadence (weekly vs every 3 weeks). Eumathes's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 82%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Vaia sells 15 in-app purchases, starting at $2.99 per month and Eumathes sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Eumathes holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Vaia has 1.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 82% of Vaia's written reviews are positive against 100% of Eumathes's.

Vaia ships an update weekly, Eumathes every 3 weeks. The most recent releases landed on September 24, 2026 and June 4, 2026 respectively.
