Ratings and reviews

Thread pitch gauge is a great reference for all those with an engineering bent of mind. It's easy to use, and the automatic screen calibration definitely helps. The app is updated regularly, which is something you don't see often with apps of this type. Overall, definitely a handy app you want to have around in your phone or app library.

Downloaded to quickly identify a small component with very fine threading. Unfortunately the app did not seem to contain this size in the visual profiles, but I was able to use the on screen ruler to more accurately measure the thread spacing. Harbor Freight cheapo digital calipers confirm ruler is plenty close enough without any calibration on Moto E4, just downloaded and opened. Removed for space, but will remember this app for future projects.

I find myself using this app all the time, to check the pitch on an oddball screw. I rarely use the ruler, because I can estimate pretty well, but it's been useful to have. My only wish is that it had a way (advanced/difficult would be okay) of requesting that _all_ thread pitches be shown. If you deal with antique machines made before thread standardization, you'll know that it's not uncommon to find something like 30tpi. One of my antique sewing machines actually has a screw with 23 threads per inch. (Really!) I think there may be a Pro (paid) version of the app -- I'd definitely pay if it had all the thread pitches. Other than that, the app is great.
