Very useful shopping around stores

How many times we go to an store and is not sure if a table fits on a corner or a curtain covers our window, etc. Now I can use my ruler on my house and on stores that do not provide way to measure.

Inaccurate—measures 9% short on iPhone 7+

I made the mistake of trusting this app for dimensioning a project. I didn't need sub-millimeter accuracy, but I did need it to be within a couple mm in a distance of approx. 50 mm. It was way off. Comparing it to a physical ruler and a trusted tape measure, it measures 9% short on my iPhone 7 Plus. What it calls 10 cm is really 9.1 cm. Its "one inch" is roughly 29/32 of an inch.

I don't know if this problem is limited to Plus-sized screens, but the app should be aware of the device it's running on and what that device's dot pitch is so that it can display the ruler accurately. Nine percent short is not a trivial inaccuracy.

Hi. Thank you for feedback, please try to update Ruler, now it's works fine on 7 Plus and others.

Stop please

It’s a simple and useful app, I checked measurements. Please stop asking me to update though. I have a phone that works perfectly well yet isn’t the latest and greatest version. Your app keeps showing up in my updates list for about a year though it’s only applicable to newer phones. Stop. Please stop or I’ve got to delete it and start carrying my old school tape measure. Repeat, do like the app but thats driving me nuts.
