# RespiRelax+ vs Cellublue

The clearest difference is rating: Cellublue at 5.0 against RespiRelax+'s 4.1. Cellublue also leads on update cadence (every 9 days vs every 3 weeks). RespiRelax+'s advantage is ratings volume (16 vs 1). On price, review sentiment, 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.

Cellublue holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: RespiRelax+ has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 70% of RespiRelax+'s written reviews are positive against 68% of Cellublue's, so the app with the better star average is not the one people write more warmly about.

RespiRelax+ ships an update every 3 weeks, Cellublue every 9 days. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
