There is no instruction on how to use this program eventho it seems simple. I still can't figure out how to get the math symbols or math functions to appear when I want to add my formulas. The sample screenshots of the function keys does not appear in the program when inputing your formula. It is pretty useless unless they fix it.... Good idea but lacking in execution.

Good info, but crashes allot

Developers for Gods sake, why have you complicated such a potentially wonderful app to the point that has rendered it useless?! Gentlemen, before putting this out to be sold to the public, you should have gotten a second and third and many opinions on it to know if it can be used. It is a wonderful idea but such a poor execution of it that it is a real shame.

I purchased this app and realised that many of teh formulas seemed to contradit what i had been taught in class. When i checked my notes and books i realized that they were inacurrately defined....... For example the cos(-1)x. Most seem to be acurate though so if you are only using it for occasional reference it should be ok

This application is easy to use and provides a great database of useful formulas that you will experience at all levels. From the most basic algebra to multivariable calculus. The add formula is also a great tool where you can record your own formulas and thereoms or make your own creation to impress your professor or that cutie sitting next to you.

This app doesn't have that many formulas. It is advertised to have Math Formulas (hence the name,) but most of them are calculus formulas. There aren't any algebra formulas! Plus, the formulas are only images, and the font in the images changes depending on the set of formulas. Also, if you want to add a new formula, it can freeze after typing in the name and selecting it. The interface to do so has small buttons and is difficult to use. There are much better apps out there!

I'm currently enrolled in a calculus course and this app helps a ton when I'm doing homework!

As a math teacher, it is nice to have a quick reference to so many formulas that you need to remember for calculus problems and beyond.

Has potential and I would love a formula creator/editor. Don't give up dev, give us updates. Bigger buttons, more operators, and larger fonts.
