VisualMath 4D is a professional graphical calculator. It allows you to browse through a collection of built-in functions like trigonometrical, rounding, and sum and product or you can compute your own. Functions can be drawn in 2-D, 3-D, and 4-D all with a time variable. You’re also able to save your functions, rotate and zoom in on the graph in three dimensions, and display multiple graphs at once.

Fast Camera is indeed fast. It’s able to snap up to 1,800 photos per minute beginning immediately after launch. This is the fastest capture speed of any app in the App Store. You’re able to sift through the photos and save only the best ones to avoid wasting storage space. But the feature list doesn’t stop there. Not even close. Fast Camera also includes focus and exposure lock, white balance control, customizable delays, a timer, location data, a burst mode, and the ability to export content as time-lapse videos.
