# OOONO vs sonnen

The clearest difference is rating: sonnen at 3.5 against OOONO's 2.0. sonnen also leads on ratings volume (20 vs 1) and monetization model (free vs ad-supported). OOONO's advantage is review sentiment (57% vs 38%). 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.

sonnen holds the better App Store score, 3.5 against 2.0. That said, the two scores are not equally well evidenced: sonnen has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 57% of OOONO's written reviews are positive against 38% of sonnen's, so the app with the better star average is not the one people write more warmly about.

OOONO ships an update every 3 weeks, sonnen fortnightly. The most recent releases landed on September 25, 2026 and September 26, 2026 respectively.
