Instant Unit Calc

A simple, no-fuss calculator app that stays smooth even with ads.

Simple Calculator combines a calculator and a unit converter in one app -- see your result converted into other units as you type, no switching required.

Key features:

• Handles complex expressions with parentheses, not just the four basic operations
• An always-visible conversion panel across 5 categories: length, weight, volume, area, and temperature
• Mixed-unit math like "2 cm + 3 kg" -- results are kept per unit instead of forcing a wrong conversion
• Real dimensional analysis: "3 m × 4 m = 12 m²" -- multiplying and dividing changes the unit correctly
• Cross-category multiplication/division shows a synthesized unit, like "10 mL ÷ 2 kg = 5 mL/kg"
• Define your own custom units, like "1 gold coin = 17 silver coins, 1 silver coin = 23 copper coins"
• Three themes: Light, Dark, and follow system setting
• A focused, uncluttered interface -- no extra features to get in your way
