iformula is a math formula, equation library, which was specially developed for academic students, engineers, high school students with math courses and scientist with higher mathematics skills.

Do you also sometimes forget equations, formulas you have learned very hard years before at school, university or somewhere else ? Now you need them again ? The solution is called iformula !

Where ever you are, at the campus or at your company or anywhere outdoors - if you have something to calc - iformula is always with you !

There is no need of carrying around heavy paper mathematics library books anymore - iformula is your right choice !

I don't agree with Barry at all

I'm a Master of Science for mechanical engineering and I'm teaching mechanics at an university in the States. I personally absolutely do not agree with Barry's statement above ! I use this app every day, of course you have to teach yourself using it and some submenu's should be organized better, think of the good old days when we first used an HP 48 calculator and RPN, what a change of thinking. I also advise all my students using iformula for exam preparation and they are allowed to use iformula at the exams too ! May be Barry get stuck at K-12 calculus..... A good advise: higher maths does not only consists of calculus theorem !! If you memorized the tree structure of iformula lite it would be a good idea to spent some money for the pro version, which has much more topics and many helpful features. This is only my opinion - An opinion of an engineer, who worked for more than 15 years in the aviation industry and now "only" teaches at an university !

I hope these help some people who like math like me any further.
best regards

As an illustration of the problem of Obsessive-compulsive Disorder, this app is pretty good. As a math resource, this app is less than worthless.

For example, the Constants menu has seven submenus, titled Constants I-IV and Useful Constants I-III. As you can see, the titles give no hint of where you'll find the constant you're looking for. What's there is a mishmash of physics and chemistry constants with many important ones missing. They are arranged neither alphabetically nor by subject matter. And Constants II and III are the same!

Similar problems abound throughout. There are tons of formulas and diagrams you will never need, while many important basic ones are missing. At least once the end of a formula was clipped off the page.

It's written in a mix of German and English using (apparently) German math notation. For example ":" is used for division rather than "/".

Even for $0, this app is a rip-off, because of the price you'll pay in headaches and wasted time.

This app is so confusing it will make you feel stupid. I teach calculus for a living and I can assure you, the app is stupid, not you.

Nice app to have...

...don't have to google things I can't remember any more. One suggestion would be to resize the images to fit the screen - a few of them run off the side or bottom.
