DataAnalysis is a general purpose iPad App for the plotting and fitting of all types of data that can be formulated as x,y pairs. The program can be used easily by both students and professionals. It is particularly useful for quick analyses of various types of data by curve fitting, value prediction via a standard curve, and analysis of kinetic data including enzyme kinetics.
Data can be entered directly via the keyboard or imported from the Mail App as a text file (.txt), and comma separated value file (.csv). In addition, data can be imported via drag and drop within iTunes. Data files in txt, csv and native formats can be imported directly from Dropbox.
After data entry the user has the option to average, baseline correct, and/or normalize the data before plotting and fitting.
Plotting of the data is as simple as pressing the Plot button. The axes are autoscaled and the graph is immediately ready to add to a document or presentation. The user has a variety of options to customize the graph by altering the axes, axes labels, graph title, and changing the symbol, its size and color.
The data can be fit to a variety of mathematical equations by non-linear regression including simple functions such as linear, 2nd and 3th order polynomials, power, exponential, log functions.
Data can also be fit to more complex equations for such processes as radioactive decay, enzyme kinetics, 1st and 2nd order chemical reactions, as well as gaussian, logistics and surge functions. The fit can be overlaid on the data with different line widths, types and thicknesses.
For many analytical situations, the data fit can be used as a standard curve to determine the value of unknowns. This analytical procedure is completely automated within DataAnalysis.
The program output, graphics and text, can be copied, emailed, or uploaded to Dropbox in a variety of formats including PDF, PNG and TXT. The graphics in PDF format can be edited with programs like Adobe Illustrator™ as objects.
DataAnalysis also supports multitasking and printing of input data as well as all forms of output.
DataAnalysis has built in tool tips, comprehensive web based instructions and how-to videos available via the Help Menu.
What's New in Version 2.0.30
Fixed bug that caused the lower button bar on Data Entry page to disappear on last version.
Top and great
Yes it is the best. Please make it possible that we can write the proper equation ourself because we encounter with the data that can't fit with the none of the available functions. Thank you.
This is a high quality application with excellent customer support.
I like it. ♥️💙💜💚💛 It is excellent. Thank you for updating. Please add fourth-order polynomial which is needed a lot.
