What's the purpose of this app?
The app helps visualize the proportional difference between two numbers, making abstract numerical comparisons more intuitive and understandable.
Can I compare very different values?
Yes! The app automatically scales the shapes to show the proportion between values, no matter how different they are.
What do the "Together" and "Apart" options do?
- Together: Shapes touch at the middle line, emphasizing their connection.
- Apart: Shapes are centered in their respective areas, making individual sizes clearer.
How do I save my settings?
After customizing shapes and colors, tap the "SAVE" button in the settings menu to store your preferences.
Can I restore my previous settings?
Yes, if you've saved settings previously, a "LOAD" button will appear in the settings menu to restore them.
What if I enter zero for both values?
Both shapes will disappear until you enter non-zero values.
Is there a limit to the values I can enter?
The calculator supports standard numerical ranges. For practical visualization, extremely large ratios may show one shape as very small compared to the other.
Can I use this app offline?
Yes, the app works completely offline once installed.
