# ONE! vs Grata

The clearest difference is ads: ONE! at none against Grata's shown. ONE! also leads on monetization model (free vs ad-supported) and iOS requirement (12.4 vs 15.0). Grata's advantage is update cadence (every 6 days vs every 5 weeks) and review sentiment (45% vs 23%). On price, rating, in-app purchases and device support there is nothing between them.

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

ONE! holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Grata has 395 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 23% of ONE!'s written reviews are positive against 45% of Grata's, so the app with the better star average is not the one people write more warmly about.

ONE! ships an update every 5 weeks, Grata every 6 days. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
