An iPhone (and Android) application developed in React Native using TypeScript.

The app itself is rather simple, as the name suggests. It is just a small calculator app that supports addition, subtraction, multiplication and division, both with integers and with decimal numbers. The app rounds decimal numbers to 4 digits, and the maximum input length is 8 digits.

The app is not available on App Store or Google Play, just locally on own device via Xcode

After cloning the project, first run the following command:

# Install all dependencies
npm install

Then choose one of the following options:

# Run the application in iOS Simulator
# (requires Xcode)
npm start

# Alternatively without Xcode
# (requies Expo CLI)
expo convert

# Run the application in Metro
npm start

1. Make sure to have Xcode installed
2. Register for an Apple Developer Account (use this when signing in to Xcode)
3. Connect your device to your computer
4. Open ios/BasicCalculator.xcworkspace in Xcode
5. Make sure your device is selected as "simulator"
6. Press Build and Run, then wait for app to install
