Formula MAX

For some people who knows a lot of information there is nothing there.I expect to see more there but for .99 cent ?? Give me a professional app for 99$ and I'll be more happy.

Great app, particularly the math section. It has so many formulae, it is well organized and things are easy to find. Very useful app that saves lots of time. Great reference app!

Lots of information included with this app, but lots of basic stuff missing also like a ready reference for constants, or basic quantities like the mass of a proton. Overall worth the price.

As a Physics major, I'm so glad someone finally came up with an app that has a useful quick reference for integration formulas and while bunch of other useful stuff!

I give them high marks for having an up to date periodic table in the Chem section

One of the best app for students and teachers...

This is a collection of flash cards for children: When you call up an equation, for instance, it is just a pictorial image, meaning that it is not interactive. So you cannot actually use it in any way, and you cannot even copy it into the memory of your iPhone. All the knowledge base is also extremely basic: If you call up "electrons," for instance, the non-interactive flash card tells you (with a spacing error) something that you may be taught at an elementary school (junior high?), but certainly not at a college level. So if you are a college student, you certainly cannot use this app even for the very 1st year.

Its a great app but its a bit hard to understand unless you r a student in ap chemistry or physics

There are a lot of topics in the chemical section that includes concepts , however, there needs to be more formulas relating to thermodynamics, heat capacities, types of radioactive decay (with formulas), shrodinger's equation, Heisenberg's actual equation, nomenclature, chemical equations relating to gas formation and precipitation, and solubility rules to name a few. Maybe better classification with gas laws, thermodynamics, radioactivity, chemical equilibrium, stochiometry, periodic table, quantum chemistry, the net ionic equation versus total ionic equation, Redox reactions, and light/wavelength chemical equations sections would be a step towards making this app a bit more organized. Chemistry is generally mostly mathematics. It's still a pretty good start and if it's fixed I will recommend .

Getting my BS in engineering has been challenging! This app will definitely help me visualize and memorize key formulas come exam time.
