TLDR: here's react-native sleep tracking & sleep coaching app that I've been building

In January 2019 I took a big leap into startup entrepreneurship and started building an app that could provide advice on how to improve your sleep based on your sleep tracker's data. When I started building it I had very little experience with React and even less experience with React Native. Because of having so little experience, I was afraid to make the code publicly available despite wanting to do it so from the start.

Few weeks I finally found the courage to clean the project and switch from private Gitlab repo to a public Github repository. You can find the full code here. I've tried to provide all the necessary instructions on how to run it locally, but there might be a few mistakes on my part here and there. Please let me know if/when you come across them.

Why this project might be interesting to you?

As mentioned I built it with React Native, while originally having very little experience on it. I would like to say that I've improved a lot since starting out, so in a way this project works as a timeline of how I learned to build stuff with React Native. There are parts in the project where the code is really ugly, but also parts where I'm a little proud of it even.

To give a little rundown of the app here's what it can do:

• Import sleep data from the following sources
  • Apple Health
  • Google Fit
  • Oura
  • Garmin
  • Polar
  • Fitbit
  • Withings
• Save data to Apple Health
• Create trackable habits
• Show stats based on sleep: bedtime window, average sleep, sleep trend, shortest night, longest night, etc.
• Save data to Nyxo Cloud Service, which is built with Aws Amplify
• Display content about sleep from Contentful
• Works on both iOS and Android

There also some more boring features, which you can explore better by downloading the app from either App Store or Play Store. One really crucial thing that is missing is onboarding, which I'm hoping to add as soon as possible.

Tech

The app is built with the following stuff:

• AWS Amplify: S3, Cognito, AppSync, DynamoDB, Aws Lambda
• React Native
• Redux, reselect, redux-offline
• react-native-reanimated
• react-native-svg
• Intercom

Continuity

This is project is also very much alive and I'm contributing to it daily. If you like the app, I would really appreciate it if you give it a star either in Github or in App store / Play store. It would mean a lot to me, and make my whole week :)

PS.

I've also built another app during the past year. This app also doubles as a website for Nyxo, as it's built with Gatsby, Amplify, TypeScript, Styled-components, and react-query. You can find that project below:
