NoTestudo

NoTestudo

A React Native behavior-change app that I coded entirely for narb. It integrates a wearable API over OAuth, with background sync, local storage, and optimized geolocation. NoTestudo won the UMD xFoundry Oura Ring Challenge.

NoTestudo is a behavior-change app that narb built for the UMD xFoundry Oura Ring Challenge, which it won. I coded the entire app. It's built in React Native and integrates a wearable API through OAuth, with background sync, local storage, and optimized geolocation. The screenshot shows mock data and is labeled that way.
