Submitted by: Daniel Jiang

Time spent: 8 hours spent in total

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.
• User can select between tip percentages by tapping different values on the segmented control and the tip value is updated accordingly

The following optional features are implemented:

• UI animations
• Remembering the bill amount across app restarts (if <10mins)
• 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:

• User can select a tip percentage from 0% to 100% as the tip percentage using a slider
• User can only type in numbers with a number pad and the digits will be appended to the end of the bill amount starting as a decimal
• User can tap outside of the number pad to hide the number pad
