Key result
Participants perceived the Breeze 2 gameful breathing training app as engaging and effective (P<.001), with the breathing detection model achieving a multi-class balanced accuracy of 74%.
Why the study?
Slow-paced breathing training benefits physiological and psychological well-being, but adherence to breathing apps is low, which gameful training may help overcome.

Supports pilot testing of gameful breathing apps; leaves open whether 74% accuracy improves clinical outcomes.
p-value: p=<.001
The Breeze 2 gameful breathing training app was perceived as engaging and effective, and its novel real-time acoustic breathing detection algorithm demonstrated good accuracy.
Lukic et al. (2022) studied this question. Breeze 2 app was evaluated on User engagement (UES-SF), perceived effectiveness (PE), and perceived relaxation effectiveness (PRE) (p=<.001). Participants perceived the Breeze 2 gameful breathing training app as engaging and effective (P<.001), with the breathing detection model achieving a multi-class balanced accuracy of 74%.
