Alphawin

Alphawin is a bill splitting calculator built around one clear flow: enter the bill amount, choose a tip percentage, select the number of people, and view the updated totals.

🧾 BILL INPUT

Enter the bill amount in the main value field.

The field accepts decimal values, including amounts such as 86.40.

If a negative bill amount is entered, Alphawin shows a warning.

The bill value can be edited at any time. When the amount changes, the displayed totals update automatically.

⚡ TIP SELECTION

Alphawin includes four preset tip options:

• 10%
• 15%
• 20%
• 25%

Tap one percentage to apply it to the current bill amount.

The selected tip option remains highlighted.

Changing the selected percentage updates the tip amount, total bill, and per-person amount.

👥 PEOPLE COUNTER

Use the minus and plus controls to set how many people are sharing the bill.

The available range is from 1 to 99 people.

Tap minus to reduce the number of people.

Tap plus to increase the number of people.

The full total is divided evenly across the selected number.

📊 RESULT VALUES

The result section shows:

• Tip amount
• Total bill
• Each person pays

Tip amount shows the value added by the selected percentage.

Total bill shows the entered bill amount plus the calculated tip.

Each person pays shows the total bill divided evenly by the selected number of people.

All result values use US dollar formatting with two decimal places.

The per-person amount appears as the main highlighted result.

🔄 AUTOMATIC UPDATES

Alphawin recalculates when any active value changes.

The results update after:

• Editing the bill amount
• Selecting another tip percentage
• Increasing the number of people
• Decreasing the number of people

There is no separate calculation button.

👆 TOUCH CONTROLS

Alphawin uses text input and tap controls.

The interface includes:

• Bill amount field
• Four tip buttons
• Minus button
• People count
• Plus button
• Tip amount result
• Total bill result
• Per-person result

The tip buttons use a compact grid with large touch areas.

📱 SCREEN LAYOUT

Alphawin uses a single-screen mobile layout.

On wider screens, labels and amounts can appear in aligned rows.

On narrower screens, the content can move into a vertical arrangement.

🎨 VISUAL STYLE

Alphawin uses a deep blue gradient background.

Information appears inside panel cards with accent highlights.

Labels use muted text, while calculated values use larger text.

The per-person amount uses stronger visual emphasis than the other results.

📌 DEFAULT STATE

Alphawin opens with default values already shown, so the current calculation is visible when the screen loads.

📌 CLEAR FEATURE SCOPE

Alphawin focuses only on calculating a tip, adding it to a bill, and dividing the total evenly.
