This is the first of PhoneLab’s series of web-based Lab apps that will work on any Mobile or Tablet Web browser. Please try it out:

It not only records data, it also plots it online. It can also email the data in Excel format with a pre-plotted graph. This app should reduce acceleration based lab times by about 1/3 as it removes the tedium of data taking and plotting, allowing time for students to do more interesting experiments. More importantly, it allows them to do their own experiments with their own device.
