Review: Here’s another school related app in honor of the end of the first school week.  This is a graphing calculator with great options.  Inputting your equations is easy and simple.  You are allowed to have six equations on the graph at a time with a different color for each.  You can easily find intersection points and axis intercepts with special buttons.  When you graph an equation, you are able to tap and hold your finger then drag to come up with single points.  On the options menu you can adjust your window (easier to just pinch and stretch on graphing screen) as well as reset your view.  You are also able to turn your labels on and off and select the sampling quality.  There is also an extensive help screen which will get you using this app’s many functions quickly.  As an extra bonus you can use this app in landscape mode.  In terms of other competitors on the app store, there is an app called Touchplot ($4.99) which was a massive waste for me.  You cannot graph more than one function at a time and you can’t use brackets.  On top of that Touchplot’s interface was hard to use.

Verdict: I highly suggest picking up this app if you are in any math class at the moment.  It is 1/50 the cost of even the cheapest graphing calculator and who wants to go on their computer if they need to graph something?  Stay away from the competitor’s Touchplot app because from experience it has minimal function.

Review: In honor of school starting tomorrow I decided to review an app themed appropriately.  This app is a scientific calculator which is close to the same Apple provides you (landscape mode version) but with more features.  Imagine yourself walking down the street trying to remember the Cos of 180 degrees.  Now you can just whip out your TouchCalc app and figure it out in seconds.  This app is really helpful for basic calculations when you just need to use a calculator quickly so this won’t help you when doing advanced stuff.  Still this calculator has a memory along with the normal scientific buttons and can work in three different modes.  Also the buttons seem to be just the perfect size which is good because this app doesn’t work in landscape mode.  The settings screen is pretty basic and is where you change between you modes and other prefences.

Verdict: Pretty good calculator app for basic use but won’t help you much when trying to do advanced calculations.
