Is it possible to test accelerometer inputs when running a pad/phone game from the Editor? I have got it to run on the device, but putting it on there is a lot of faff. And considering only taps are detected, there doesn't seem to be much use for the preview beyond checking the thing actually runs at all.
I know you can't get an accurate result without an actual accelerometer, but I'm not interested in an accurate result. I just want to be able to move the axis values to nudge the thing approximately.
Unity Remote does all of that. Check your manual docs for the full details. If you don't want to build the app yourself you can download it from the App Store, just search for Unity Remote.
EDIT : As pointed out by equalsequals in the comments, currently Unity remote does not work with the iPad, however there is a special build setting that allows you to deploy to the iPhone simulator but only with iPad builds. The simulator only uses a software renderer though, so it doesn't handle intense graphics very well and isn't a good indication of final performance.
