We’ve built in over 50 physical constants for easy access: from Boltzmann’s constant to the mass of a proton.

The symbolic output mode makes it easier to make sense of your answers: if your output is a rational fraction, a multiple of pi, or a square root, we’ll show you the result in those terms. In addition, we’ve added engineering output mode.

Behind the scenes, SciLine uses the gold standard for equation rendering—LaTeX—so your equations will always look great!

Very Useful App, Excellent Customer Service

I tutor algebra. I needed an inexpensive app that would show the answer in either decimal or fraction form. After playing with the free version, I bit the bullet and paid a couple of bucks for the premium version. I have been really pleased. I made a couple of suggestions to the developer, who responded right away. He implemented one of my suggestions in the next revision and is looking into adding the other one. I tweeted him when I couldn't find the button to push for a particular operation and we tweeted me right back with the answer.
