# Zeffy vs Y.A.M.S

The clearest difference is rating: Y.A.M.S at 5.0 against Zeffy's 2.9. Zeffy's advantage is ratings volume (49 vs 4) and chart position (#171 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Y.A.M.S holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: Zeffy has 49 ratings behind it against 4, so its average is the more settled of the two.

Zeffy ships an update fortnightly, Y.A.M.S every 8 days. The most recent releases landed on October 18, 2026 and October 4, 2026 respectively.
