Refresher, in the words we use.
Boilerplate
Refresher is a breathing pacer. It runs box breathing at 4-4-4-4, 4-7-8, coherent breathing at a 5.5 second inhale and a 5.5 second exhale, the Wim Hof method and five more, holding every phase to the second. Each session records your heart rate before and after, measured on Apple Watch, and shows your HRV alongside the days you practise. It runs on iPhone, iPad and Apple Watch, writes to Apple Health, and needs no account.
One line: A breathing pacer accurate to the second, with your heart rate before and after every session.
