Custom pacing & HRV tools
Breath Ball
Breath Ball pairs an adjustable breathing pacer with optional heart-rate and HRV tools. The developer now describes all features as free, supported by voluntary donations, rather than a feature-unlocking subscription.

When it may fit
Consider it if setting your own breathing pattern is important, or if you already have a compatible heart-rate sensor. A basic pacing session and a sensor recording are separate capabilities.
What it offers [1][3]
- Editable breathing patterns and visual cues
- Audio guidance and background sounds
- Optional heart-rate recordings and HRV analysis
What to weigh up
Start the comparison with the pacing controls. Treat HRV as an additional feature to investigate, including device compatibility, rather than a requirement for using a breathing app or a measure of its clinical effectiveness.
- Sensor features require compatible external hardware.
- A heart-rate recording does not directly measure the breath itself.
Provider practice guidance
The developer's legal notice says it is not authorized as a medical device and provides practice cautions; read that guidance at the source. [5]
