Emailed the developer who said the accuracy is affected by the environment and the quality of the accelerometer. My phone is the HTC Incredible which has a good sensor (according to him). For the environment, the magnetic field is the primary concern. If the values are within 40-60uT, it is perfect. Given my phone and a magnetic field of 40-60uT accuracy will be within 1-2 degrees. You would expect the magnetic fields in a shop to be much higher than 60uT.

Now I truly have no idea how this stuff works so I did the simple man’s accuracy check…I zeroed the device, tilted the blade to 45 degrees, checked that w/a combination square to where I was comfortable that it was a good 45 and checked w/the phone and got a reading of 45.1. That’s pretty good in my book.

DS251, my question to you is how would the wixey gauge differ? Would they use different transducers and accelerometers or be based on a completely different concept?
