I had been using the free version of this app for 6 years and loved it. I decided to upgrade finally and it is worth it. I like that I can now save measurements and measure in two directions at once. The "always on" feature is great too when you are studying the size of something for a few minutes.

Instructions??? I hoped that by paying the $1.49 for the "Pro" version I would get access to some instructions or some Tips & Tricks. Not the case. It doesn't appear that there's any difference between "free" or "Pro" although I could be missing something. 🙄

I bought this third ruler for the calibration skills one needs to set it right. The first one is free, two-point lateral measure. The second a handheld, lay down the object and use sliders. This One I bought to tell my production supervisors and material quality management teams at a solar cell place about defect (class B and C removal) allowable sizes, like 0.02 by 0.04 mm, then I could describe defect sizes to team reviews of performances.
