Hello there, i hope this is the right forum(if a phone counts as computer) for things like that. in recent days I developed an android app called BlueGraph mainly for msp430, but also tested with arduino, which simply reads from blueooth via serial port profile and plots realtime graphs for the incoming data.
The data has to be in a format like: (integer)(seperator)(integer)...(\r\n) 123,142,1241 //would produce 3 graphs with real time data
There is also a logging functionality which simply writes the incoming data to a log file.
The app is free and ad_free.
I uploaded a short demo video to youtube.
If you have any suggestions or feature request, please write here or in the play store comments :)
