Calculator!! downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.

how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

About Calculator!!
Calculator!! has the following additional functionality compared with most available calculators:
- Shows the expression as you enter and keeps a history of your calculations (Swipe up on the screen to access the history.)
- Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations.
- Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format.
- Capability of calculating permutation, combination, Least Common Multiple (LCM), and Greatest Common Divisor (GCD).
- Quadratic and system of two linear equations solver
- Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers)
- Throws a set of dice (choice of 1 die to 4 dice)
- Backspace to delete last digit entered.
- Tip Calculator
- Geometry Calculator
- The left pane scrolls to reveal more functionality without a need to switch modes. The digits and most common operations are always visible and the less common operations can be revealed by scrolling the left half of the screen.
- Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians.
- Showing the content of memory on MR button, as long as it fits.
Calculator!! is an ongoing project and we are working on more features and functions to be added to every update of the app.
You are going to love the simplicity of the user interface and you will get used to the extra functionality added to this product.
Please do not hesitate to contact us for any questions, comments, to report any bugs, or to suggest additional functions you would like to see in the upcoming updates.
