Shake Calc - Calculator

Ralf Schroth

About this app

A fully featured scientific calculator with a neat twist. It calculates when you shake your phone. For your everyday calculations it features an easy to use basic view with direct access to all the most used functions. For complex calculations you can switch to an advanced view with a simple swipe of your thumb. Both views offer large buttons for easy usage on small and large devices.

Features:
- Entering entire expressions
- Calculation history with support for copying old results to calculator memory or clipboard
- Full support for Percentages (50 + 10% = 55!)
- Calculation memory support
- Trigonometric and hyperbolic functions in radians, degrees and grads
- Predefined list of most used physical, chemical and mathematical constants
- Possibility to define custom constants for often used values
- Advanced result formatting with digit grouping etc. (customizable)
- Supports devices with large screens like Galaxy Tab or Xoom with optimized layout and large keys
- Supports different Themes (Classic, elegant & colorful)

Hints:
- To access advanced memory functions (M-, MC) and hyperbolic functions use the “2nd” key
- A short touch of the “C” key deletes the last digit/function, a long press clears the entire expression

Ratings and reviews

Amazzzzingggg!!!! I've had this on my old phone and couldn't figure out how to change the theme, which is why I didn't have it on my new phone. Finally, I downloaded it again and figured out how to get to the settings. I had to hold down the square button or the button on the right of the home button and back button. Then, wolla hit preferences and you're in. I can't believe I lived without you this long. I'm back sweetheart!!!!! ❤❤❤

I've used this app for years. It is great. I had to upgrade my phone to Samsung S22 and I keep getting pop-up messages that this app was written for an older phone. Please developers, upgrade the app for newer phones.

Works very well. Very easy to read. Limited themes are fine. Used it for a few years on phones and tablets. Shake function is fun, but later turned it off. Just loaded this on my new Galaxy S8 phone. Thanks!
