When considering Digital inclinometers, compare the specs carefully. Readout to two decimal places is better than one place but only if the resolution is the same.
Most specify a resolution of .1 degrees but I’ve seen some that are only .2 degrees.
Also look for the frequency at which the device updates it’s position.
When setting the table saw blade to an odd angle I stick a Wixey box to the blade but I noticed when I cranked the tilt wheel fast I could see the angle curser move continuously but the Wixey display changed increments at a much slower pace. I have to crank very slowly when approaching the target angle and even then I can see the hardware curser move between one tenth degree and the next. So, when I need very fine adjustment I go back to making supplemental increments for the built in bevel gauge and use a flashlight and reading glasses to hit the mark.
