Avoid at all costs - inaccurate, wholly incomplete & twice the rubbish it needs to be since everything in two languages. Again, how did Apple let this nonsense through? ### 1/5 — basic *2010-05-08* The formulas contained in the app are very limited not worth the $5. ### 1/5 — Pretty Lame *2010-01-26* After reading the reviews I was hoping for something much better. Pretty basic stuff that could probably be found easily for FREE on line. ### 2/5 — Why Doesn't It Work on the iPad? *2013-04-18* This app seems to be very good, however it will not work on my iPad which is a big inconvenience. If I want this type of software, I have to buy a different product from a different company in order to run it on my iPad. ### 2/5 — Meh *2011-07-21* Unless I'm missing something this is pretty lame. Only one page/ formula, no calculators, no examples. ### 3/5 — working good *2010-02-03* good app ### 3/5 — ok *2010-02-03* ok ### 4/5 — very useful *2010-02-03* I work for the Nasa - it is a very very useful tool, good app- go on !! ### 4/5 — wow *2010-02-03* good tool !! ## Most praised reviews (8 highest-rated) ### 5/5 — Great application and creator! *2010-11-24* As a University student, studying Mathematics, and as a high school Mathematics teacher, I have found this application extremely handy. Not only are the equations useful for my studies (when trying to remember double angle formulas), but the equations and many accompanying diagrams are also helpful and a great teaching tool for my students (especially the angles in parallel lines, which was added very promptly at my request). This is an amazing app an is well worth the money! Thanks again. ### 5/5 — good *2010-01-20* good !! ### 5/5 — very good *2009-11-29* very good app, thanks ! ### 5/5 — Good app *2009-09-20, version 0* Seems like a nice little app, lots and lots of useful equations. Definitely worth 59p. Two things I would like I see added. 1) Just make it more graphically pleasing. In some places the drawings are cut off by the edge of the page. Maybe put a bit of colour into it. 2) A quick and easy search function would be nice. Apart from that, thumbs up! ### 5/5 — very rich content, amazing ! *2009-09-02* i like this math library - it meets exactly my math standard ### 4/5 — love it *2010-02-03* i love it, would buy again !! nice app ### 4/5 — better that i expected *2010-01-26* i really did not expect much for this price, but surprise it is a useful math iphone tool !! ### 4/5 — wow *2010-01-20* nice, classic math ref. - all what i need now on my iphone !! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
