For anyone looking for just a Sketch solution, I'd recommend Sketch Measure. https://github.com/utom/sketch-m... Free plugin that looks like it includes some of the basic functionality. I've been using it with all my clients recently. Saves a ton of time for everyone involved.

This looks super useful. Years ago I worked with a designer that spent ~30% of her time annotating specs (!!!).

Reminds me of Zeplin
