This app reminds me of Khan Academy, but it only contains lessons from four mathematics courses – Pre-Algebra, Algebra 1, Geometry, and Algebra 2. Also, it is a lot more costly than Khan Academy – more on that below.

Students can either search for a lesson or choose one from the listed courses. Each course contains between 9 – 13 chapters (read chapter titles below). Each chapter has at least a dozen lessons/concepts. Each lesson/concept provides an extensive opportunity to view examples, practice, be challenged, complete a self-test, and have access to worksheets and notes. Many of the examples link to video clips that explain each concept.

Although this app is free to obtain, only the first five lessons completed are complimentary. After that, courses can be purchased in-app for $9.99 each or all of them for a total of $39.99. Proceed cautiously; the price of this app can quickly become steep. Khan Academy may be a better fit for your situation.

Also, please note that a wifi connection (or 3G) is required to access the bulk of each lesson’s content.
