[QUOTE I then focused on the XFR app itself. Not really a lot of "must have" features to tell you the truth. Since the microSD card has all the data, it's really easy to transfer the CSV to a PC and use excel to graph things and manipulate data. I'll be happy to send my very basic XLSX template I created for my friend to anyone who'd like it. The data in the attached example is simulated from the XFR app on the iPhone. I have NOT thoroughly evaluated/debugged my spreadsheet [/QUOTE]

Would it be possible to have a copy of that spreadsheet ??

Best regards
