Calculators can be hard to use. Calculi plans to change all that.

Calculi is a smart calculator that is simple and easy to use, but with advanced features for power users. Whether you are trying to balance your checkbook or taking an advanced math class, this app will help you with all of your calculating needs.

Calculi doesn’t just add two numbers together, but can solve complex expressions using the order of operations. So go ahead and calculate anything and everything! Press the 2nd button to reveal more scientific functions.

Calculi adapts for all of the latest iOS devices. Even better, multitasking on the iPad is supported in all orientations. The single, simple display enables you to view your entire expression.

Gestures are fun. So why not?
- Long press the delete button to clear the display.
- Long press the equals button to use the previous result.

Don’t be selfish. This history tape can be shared either as a single thread or the entire tape using numerous methods such as email, messaging, or print.

Common constants from both mathematical and scientific fields (astronomical, chemical, electromagnetic, etc.) are included for use in calculations.

Finally, if you enjoyed Calculi, please take some time to leave a review. Feedback is always appreciated for future updates.
