A dumb question probably, but on the Pinguy UI I'm struggling to make sense of what the "legs" are supposed to mean, in terms of which to adjust.

For example - if I have a pin where the front legs are wound all the way in, and the app tells me that the pitch is too shallow obviously I have to raise the back legs. That bit is fine, I don't need to look at the UI "legs" for that.

But if I have a situation where the playfield is not level side to side, I don't know whether this means I need to raise or lower the front leg, or the rear one. I'd like to think the app can tell me if the playfield is twisted, but I'm just not seeing which leg I need to adjust. I end up adjusting it based on a visual check which I'm sure is less than optimal.

I've also noticed that there is a ~0.5 degree difference based on whether I place the phone between the flippers, or at the top of the playfield. I don't know whether I should level for 6.5 degrees between the flippers (and it be e.g. 7.0 degrees towards the top) or aim for 6.5 in the middle of the playfield and have the pitch potentially less than that between the flippers?

(I could be overthinking it as well)

I have this exact problem. The phone is unstable and throws all my previous measurements out on all axis.

The only solution I can see is a case that "flattens" the back of the phone. I have a very thin case on at the moment, and hadn't realised how much of a problem this would be

Would that work? Every machine is likely to be slightly different I'd have thought. Even a millimeter of difference in playfield pivot bolt locations would translate to a playfield angle difference.

PinGuy on a watch sounds like a solution looking for a problem. You put your phone on the playfield, you get under and make adjustments according to the audible cues.

If you’re on your hands and knees making adjustments, lifting the table with your back, your hands are going to be on the floor anyway for support, and if you’re coming out from under the table after each adjustment to use a trolley, well you can look at your phone can’t you?
