Have you done any testing to determine how precise and accurate this is? I suspect their must be a lot of variance between laptops, since this isn’t an intended use case.
- alden5 1y agoThe app isn't accurate at all, magic 8-ball of scales, anything you put on the trackpad it'll settle on a weight and give you a number but it'll be random. The app will accurately tell you how much force you're applying with a finger but when putting something else on it'll settle on a random number

You can either use a 2 point calibration (aka no load followed by known load) or if you want more precision a 3 point calibration.

- cluckindan 1y agoI would assume Apple hardware comes precalibrated. Homogeneity is everything for their product lines, down to individual calibration of screens and audio hardware. It would be weird to get a new laptop and have its trackpad feel different.
