Now with Geometry, and Tip Calculator and an improved History Feature.

Scientific++ is a scientific calculator which 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 reveal 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), Greatest Common Divisor (GCD), and prime factorization.
- 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)
- Common physical constants can be chosen from a list and used in the calculations.
- Throws a set of dice (choice of 1 die to 4 dice)
- Backspace to delete last digit entered.
- 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.
- Right Triangle & Rectangle Calculator through in-app purchase.

Scientific++ 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.

Awful version keys can't be seen degrees minutes and seconds keys hidden

Please restore the original key colors back I can't see the new ones because of eye condition also degrees minutes and seconds keys should be lifted as in original

Awesome App!

Great functionality! Fraction calculations, degrees minutes seconds conversion and equation solvers, couldn't find these in a single app elsewhere. And now a right triangle calculator with some cool graphics, great work.

It may not be pretty

But brains are better! This is a hidden gem that deserves a closer look. So many scientific calculator apps get it almost right but fail miserably where it counts. This one nails it.
