# iOS/Android Client
|
||||
|
||||
[WORK IN PROGRESS]
|
||||
|
||||
This repository contains the source code for the 01 iOS/Android app. Work in progress, we will continue to improve this application to get it working properly.
|
||||
|
||||
Feel free to improve this and make a pull request!
|
||||
|
||||
If you want to run it on your own, you will need expo.
|
||||
|
||||
1. Install dependencies `npm install`
|
||||
2. Run the app `npx expo start`
|
||||
3. Open the app in your simulator or on your device with the expo app by scanning the QR code
