Instant Unit Calc
Simple, No-Fuss Calculator
Free · Designed for iPad. Not verified for macOS.
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
