Business challenge

Breathing and meditation apps are usually a timer wrapped around a content library. A user practises for three weeks, cannot tell whether anything changed, and stops, because nothing in the product measures the thing it claims to improve. The category also carries a real obligation that most apps handle with a line in the terms: breath-hold work is genuinely contraindicated for several conditions, and a product that encourages maximum holds is giving advice it is not qualified to give.

Solution

Practice is anchored to the Control Pause, a 60-second measurement the user takes once a day, which gives the product one objective marker to plan against and report on. A protocol is matched to one of five stated outcomes, and a Nervous System Score tracks progress with symptom-to-measurement correlation rather than streak counts. The methods are named and attributable, Buteyko, coherent breathing, box breathing, 4-7-8 and HRV-paced sessions, which is what lets the product be specific instead of mystical. An AI coach is grounded in the user's own measurements, mood and history, with memory across sessions, so it asks what a coach would ask. Safety is built in: comfort measurements rather than maximum breath holds, and contraindications published on the page rather than buried.

Results

  • A free tier that works permanently, and Premium at $6.99 a month or $49 a year with a 7-day trial
  • Over fifty protocols and structured programmes, with data export
  • An AI coach that reads the user's own Control Pause, mood and streak history rather than answering generically
  • Contraindications published openly, with comfort-based measurement chosen over maximum breath holds
