Comments on Ruler Pro for Android

★★★★★ Sathvik Kadidal · Nov 22, 2024
Very useful. Can be calibrated to be very accurate.
★★★★★ Bob P Wilson · Dec 11, 2017
Simple, nice, very easy to use. Pd for pro, family version Dec 10, 2017. NTS - I own pro version of this application, but it is complex, good for calculating angles and advanced measurements. I prefer Image read pro, great for storing, measuring around the house calculations (room size, Windows, doors, with a photo...very cool), and ruler pro which is great for simple, small measurements. Typically, I don't keep this app installed on my phone. (all these apps in family library, Pro versions).
★★★★★ Sugar Lampa · Feb 23, 2020
Pretty good app! Bought the pro version, would be nice if had the option to measure mm instead of cm on the counter.
★★☆☆☆ Stacey Stickle · Jul 9, 2020
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. 🙄
★★☆☆☆ Eugen BARSAN · Nov 6, 2023
It could be a perfect ruler app, but I don't understand why the text with the measurement values is not visible all the time. It is a simple positioning and font color problem. Why you are not able to see the value of a lengh shorter than 12 cm? It seems a stupid option to make the text visible only when the background color is changing umder the text. Maybe you think for an update at least for the Pro version
★☆☆☆☆ dejwar kute · May 7, 2019
I installed it because of the picture of the circle, and it's a lie, this feature doesn't exist
