Spire Breath Guide

Available in App Store. View reviews on Amazon.

Making meditation more accessible. Beginning as a self-initiated project, The Breath Guide developed into a favorite feature in Spire's production app. The first biofeedback of its kind uses real-time input of the user's breath to create the visuals. Through rounds of user testing, it developed into a gamified experience, encouraging users to attain a calmer state in minutes through paced breathing.

Intended Journey
How might we..
improve app engagement with a quick and easy relaxing exercise.
Biofeedback Opportunity

When I joined the team, Spire's App had a simple line representing the real-time breath. I grew excited about its possibilities.

Creating a mood-board, I set out to teach myself how artists created simple, yet entrancing particle physics effects that invoked a state of relaxation and escape.

Visual Research
Prototyping with the Sensor

Befriending a Firmware Engineer interning with me at the time, we stayed after hours to experiment with programs and interactive games. Modifying our device to connect to the computer allowed us to use Quartz Composer and Max MSP to prototype simple graphics that responded to the breath in real time. We presented our excitement with the team and began a process for implementing it into the production app.

Biofeedback Game Logic

From some initial tests, we found a big challenge: If the game is difficult or gets stuck, people can get even MORE anxious.

Audio Alternative

An exciting potential avenue I proposed was an audio version of the breath guide which would allow for people who are blind to experience the effect.
