Fortune Perix

Fortune Perix is ​​a percentage calculator built around four calculation modes. Choose the type of calculation, enter the required values, and view the result on the same screen.

🔢 FOUR CALCULATION MODES

Fortune Perix includes four modes that can be selected from the mode tabs:

• Percent of - calculate what a selected percentage equals for a base value
• Increase - increase a value by a selected percentage
• Decrease - decrease a value by a selected percentage
• Difference - calculate the percentage change between an old value and a new value

Each mode changes the input labels to match the selected calculation. A short formula description appears above the fields so the active calculation is visible before values ​​are entered.

If Difference is selected and the old value is zero, the app displays a message instead of showing an invalid percentage result.

⚡ LIVE RESULTS

Results update while you edit either input field. There is no separate calculate button.

The main result is shown in a large text area, with an explanation below it. For example, Percent of can display the calculated value together with a sentence showing the percentage and base number used.

In Difference mode, the explanation also shows whether the new value represents an increase or a decrease compared with the old value.

🎯 CONTROLS

The main controls remain on one screen:

• Select Percent of, Increase, Decrease, or Difference
• Enter values ​​in the two input fields
• Tap Swap values ​​to exchange the two current inputs
• Tap Save result to add the current calculation to history

Decimal values ​​are supported.

When the calculation mode changes, the app loads the default example values ​​for that mode.

📋 SAVED RESULTS

The history section stores calculations that you choose to save.

Each saved entry shows the calculation mode together with the formatted result. Up to five saved entries are displayed in the history list.

When no results have been saved, the section shows the message "No saved results yet" and a ready status.

Saving a result adds it to the history area so it can be reviewed later from the same screen.

🎨 VISUAL STYLE

Fortune Perix uses a dark interface with gradients, teal and gold accents, and rounded panels.

The mode tabs, formula description, input fields, result area, action buttons, and saved history are arranged in one vertical layout.

The result text uses a larger format than the surrounding labels so the current answer is visually separated from the other interface elements.

📱 SINGLE-SCREEN LAYOUT

The app keeps the full calculation flow together on one screen. Select a mode near the top, enter the required values, read the result, use Swap values ​​when needed, and save a calculation to history.

No additional menus are required for the four calculation modes or the saved results list.

🔄 CALCULATION FLOW

Choose one of the four available modes.

For Percent of, enter a percentage and a base value to calculate the corresponding portion.

For Increase, enter the starting value and percentage to calculate the value after the percentage is added.

For Decrease, enter the starting value and percentage to calculate the value after the percentage is removed.

For Difference, enter an old value and a new value to calculate the percentage change between them.

The result updates as the values ​​change. You can switch to another mode at any time, swap the current values, or save the current result.

Fortune Perix stays centered on percentage calculations: choose a mode, enter two values, view the result and explanation, swap inputs when needed, and keep up to five saved calculations in the history list.
