Let us know how that does in the long term. I'm interested.

I love how certain tools are switching from "dedicated tool with its own control panel" to "tiny interface box plus a phone/tablet app". This makes sense for so many things. In addition to the cable analyzer you linked, I've also seen:

- Oscilloscopes
- OBD2 analyzers
- Audio/Video mixers

Anyone else have any other examples? Or perhaps know of something which could fall into that class but no one's made the smartphone version yet?
