Great and reliable ruler app. Well put together, no distracting content. Keep in mind though, before using the ruler you need to calibrate to get accurate results. This isn't the developer's fault, but some phones don't report accurate DPI settings, so in order to get accurate distances, calibration is needed. It's easy to calibrate in the app though so it's not really a problem. Props to the developer!

This ruler app is one of my favorite apps because of it's handiness on my phone and for it's simplicity without annoying ads. Recent updates have only improved it's versatility and interactive usefulness. I find this ruler to be accurate and a must have app for a quick measurement here and there.

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

Sarah Shannon

This 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.

Very nice and convenient app with nothing to detract you from using it as needed. Would be great if user can set the start of Zero themselves due to different case used

Chris McClenny

Excellent measurement app. So simple and elegant. No annoying ads. Added this one to my productivity tools folder.

Good ruler but you need to be able to change the scale. If you had multiple scales, I would rate it a 5.

Been using this app for years. I don't use it a lot but it's a useful measuring tool to use when I don't have other tools. What's great about it is that there are no ads at all and it doesn't take much storage space.
