Calibre was founded by an engineer with the idea to use modern technology to democratize data previously only available through professional laboratories or hospitals. More specifically, by creating a smart mask that connects to a companion fitness tracker mobile app, Calibre uses breath calorimetry to provide live tracking of key biometrics like: respiratory exchange ratio (RER), VO2, VCO2, respiratory rate, breath volume, breath count and more. This opens up a world of possibilities when it comes to areas like health management and fitness tracking.
Calibre tracks over 30 unique biometrics, the only of its kind in the market.
At present, 100 units have been shipped into early adopters' hands for beta launch.
During beta launch, north of 6,300 "sessions" – aka activities, like a Run, have been tracked.
Paper Leaf was responsible for the software side of the project – not just the mobile app development and UX/UI, but also API development, firmware compatibility, and of course mask connectivity and integration. The mask itself was handled by a product design firm specializing in hardware.
Built on React Native, with a Laravel-based API, the fitness tracker app allows users to find and connect to their Calibre mask over Bluetooth, start and end “sessions” (activities like runs, bike rides, etc), compare data session over session, and more. Within each session, users can now learn key metrics like:
All data is saved to the cloud-based user profile, and after a successful Kickstarter campaign, initial batches are in the hands of early adopters.
