About this app

Dolyo is a simple, fully offline calculator that splits any amount across custom percentages.

Enter an amount, pick a preset, and Dolyo instantly breaks it down line by line and shows the remainder. Perfect for taxes, freelancer income, marketplace fees, budgeting, tips, or any
percentage-based split.

• Exact integer-cent math — no floating-point rounding errors.
• Clean, fast, distraction-free interface with light and dark themes.
