This is a nice, simplistic app that instantly fulfills your linear data-fitting needs. Finally, this handy feature is available on a mobile device at your fingertips without the need to study an instruction manual. Just open it and insert data points in the column. Tap X or Y if you wish to change axis’ names. Then, only flip the device sideways and voila!, take a look at your graph. Plenty of details such as line equation, correlation coefficient, intercept etc. are available in the menu on the upper right, as is the instant list e-mailing option.
