# Yellow Teeth vs MoodFlow

The clearest difference is ads: MoodFlow at none against Yellow Teeth's shown. MoodFlow also leads on rating (4.6 vs 4.3) and update cadence (every 5 days vs every 2 weeks). Yellow Teeth's advantage is review sentiment (100% vs 84%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Yellow Teeth sells 3 in-app purchases, starting at $3.99 per 7 days and MoodFlow sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

MoodFlow holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 161 and 140 respectively. Written reviews complicate that: 100% of Yellow Teeth's written reviews are positive against 84% of MoodFlow's, so the app with the better star average is not the one people write more warmly about.

Yellow Teeth ships an update every 2 weeks, MoodFlow every 5 days. Both last shipped on October 30, 2026.
