## What is Calculator Lite?

Tap a number and the rounded key settles under your finger. A small ripple spreads through the gap around it. Calculator Lite brings that quiet touch to everyday sums, from checking a receipt to working out a discount or estimating a travel budget.

Pick up where you left off
Tap equals to save a calculation, then recall a result from History to use it again. When you need room to think, send the result to the sketchpad and draw or write alongside it.

Scientific and percentage calculations
Work with trigonometric functions, logarithms, powers, roots and factorials. Switch between degrees and radians, or use Ans to carry your last answer into the next calculation. For questions like “What’s the percentage increase from 80 to 100?”, enter both values in the percentage calculator. It shows the change and the working, and lets you copy the result.

Currencies and units
Find a currency by name or code, such as Canadian Dollar or CAD. Reference rates are dated so you can see which quote you’re using. Your bank or payment provider may offer a different rate. Convert length, area, weight, volume, temperature, speed and time offline.

Make the keypad your own
Choose Mist Blue, Sage or Apricot and pair it with a water drop, ceramic or wood sound. Adjust the sound and haptics independently, or switch off the ripples. Calculator Lite follows your iPhone’s language setting and supports English and Simplified Chinese.

A one-time in-app purchase unlocks lifetime Pro access to the scientific and percentage calculators, currency conversion, all themes and all key sounds.
When you confirm your purchase, Apple charges your Apple Account once at the price shown. Lifetime Pro has no free trial or recurring charges.
