# BellyBio Interactive Breathing vs Mindfield eSense

The clearest difference is rating: Mindfield eSense at 5.0 against BellyBio Interactive Breathing's 4.0. Mindfield eSense also leads on update cadence (every 3 weeks vs every 3 months). BellyBio Interactive Breathing's advantage is review sentiment (68% vs 45%) and ratings volume (41 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BellyBio Interactive Breathing sells 4 one-off in-app purchases and Mindfield eSense sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Mindfield eSense holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: BellyBio Interactive Breathing has 41 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of BellyBio Interactive Breathing's written reviews are positive against 45% of Mindfield eSense's, so the app with the better star average is not the one people write more warmly about.

BellyBio Interactive Breathing ships an update every 3 months, Mindfield eSense every 3 weeks. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
