This version of the NFX Oscilloscope is due to be released very soon. Although there are more updates in the pipes, testing on different android plateforms and phones is needed. This will be a paid app, although this will be a very small price. If anyone is unhappy or the app does not work, I will offer a full refund.
The last part that needs to be added to this version is a help screen which will show how to use the oscilloscope.
See the pictures below for an idea of how the UI works.
