Does what it's meant to. Can change units (inches, cm, mm), dark/light mode, can even calibrate. Not much else to say 🤷♂️, do wonder how they calculate the default calibration tho

Chris Davies, 2024-11-28This is a simple app but it does exactly what it says it does really well. I don't know how perfectly accurate it is to the mm but it works well enough for me to get an idea when ordering components off a website how big they'll be.
