# MindSleep vs Breathe Bubbles

The clearest difference is rating: Breathe Bubbles at 5.0 against MindSleep's 3.9. Breathe Bubbles also leads on monetization model (freemium vs subscription). MindSleep's advantage is review sentiment (100% vs 90%) and ratings volume (9 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. MindSleep sells 3 in-app purchases, starting at $1.99 per 7 days and Breathe Bubbles sells 9 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Breathe Bubbles holds the better App Store score, 5.0 against 3.9. Both are backed by a comparable volume of ratings — 9 and 3 respectively. Written reviews complicate that: 100% of MindSleep's written reviews are positive against 90% of Breathe Bubbles's, so the app with the better star average is not the one people write more warmly about.

MindSleep ships an update fortnightly, Breathe Bubbles weekly. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
