I use the accelerometer all the time. With Torque, all you need is an OBD2 dongle (they are cheap and easily available) and your problem is solved. I have a magnetic mount from JB4 stuck to my dashboard where I mount my phone for easy viewing in real-time.

Another nice feature of Torque is that I can get a *real-time digital tachometer* with maximum and minimum values, which has been an itch I was desperate to scratch.

iPhone users should search the Apple App Store for "g meter"s. I found one that looks pretty good; maxG - https://apps.apple.com/us/app/maxg/id1086597366
