User Stories

The following required functionality is complete:

  • User can enter a bill amount, choose a tip percentage, and see the tip and total values.
  • Settings page to change Scene Transition
  • Navigator integrate (keep it's simple)

The following optional features are implemented:

  • UI animations
  • Settings page to change the default tip percentage.
  • Using locale-specific currency and currency thousands separators.
  • Making sure the keyboard is always visible and the bill amount is always the first responder. This way the user doesn't have to tap anywhere to use this app. Just launch the app and start typing.

The following additional features are implemented:

  • List anything else that you can get done to improve the app functionality!

Notes

  • I don't know how to hide the right triangle of React Native picker.
  • With AsyncStore, sometimes the "state" will be updated late and the "render()" will use old state.
