I'm a long time automotive technician, 19 years now. One of my specialties is electrical diagnostics and I have been using a dual channel graphing meter (snap-on vantage, the old-school brick) for most of my career.
I decided to give the N2 a shot partly for the Bluetooth capability at the price and I also like the idea of not having to beak out the snap-on brick while still being able to view signals as waveform.
It would be nice as the app progresses, if additional range settings eg. Voltage limits would be more intuitive toward manual settings rather than jumping around with the auto range or having to scale by pinching the screen.
I'm not going into too much on my first post. I'd like to see what the community thinks and if this post grows with suggestions, and I get more affluent with the N2, then I'll chime in some more. But I do think looking at the vantage interface would be worth while as it is a simple designed meter specifically for automotive, granted not as capable as this app can be.
