Hello!

My name is Rafael, I love cars and I'm a software developer.
Because of that I developed an android app called tunelogs (//tunelogs.com) to record and export data from sensors/ecu thru Hondata ECUs and ELM237 adapters.
I'm looking for feedback to improve my app and the log visualisation interface and since I saw that this is a high level technical forum I thought that I could have really useful feedback from you guys.
Any information/feedback is really appreciate :)
