This app is super accurate and easy to operate. Ever since Karen took the kids, I use this app to tighten the noose by exactly one inch every day until I can hang myself and leave this miserable existence. It also has a clean user interface.

Don\'t try to force your users to review your app when they try to close it. That\'s basic app design.

It does what it says on the tin. And not a single ad in sight - just a ruler. If I had money to spare, I\'d get the donation version. Wanna buy you a beer, dude, because this is a great app. Way too many tool/utility apps are smothered in ads. And while I get that developers need money, it makes tools hard to use. This ones considerate of that - NO advertising at all!

As a maintenance worker in a factory, i need to sometimes make measurements. Its not enough for me to carry a dedicated tape measure, but in a pinch, this app works just fine. It\'s easy ro use, read, and adjust. I only wish that 0 started slightly higher on the screen so I could get a slightly more accurate measure. None the less, this does its purpose and does it well

BE CAREFUL! On my phone the ruler is completely wrong. It says 18 cm but actually it\'s 15cm. I ordered something in the wrong size because of this app. Definitely double check that the ruler is correct on your device and CALIBRATE IT or you might lose money or worse like I just did, because of this. Annoyingly the app doesn\'t tell you to calibrate it. It\'s hidden in the three dots menu that appears when you tap somewhere.

Very simple but effective with NO ADS! Default calibration was 0.25 - 0.5 mm short on 5 cm. Drag cursors did lock up but freed with switch to night mode. Would like calibrate with CD and with calibration drag tabs wider & further from scale to get out from under transparent rulers. Would suggest in-app info and consistent branding for \"Pro\"/\"Ruler+\"

Perfect kind of app. Well-designed and ad free. Would like to remove the \"Tap anywhere to show and hide the menu\" notice and the blue history button since it blocks measurements where it\'s located and it\'s a redundant button anyway (I can just go in the menu to view the history), but that\'s mostly an aesthetic issue. Works great otherwise.
Sharon Spain 2020-12-21

Great app and seems to be accurate, although sometimes I\'d like to measure something bigger than my phone. Couldn\'t camera be used, calculating zoom setting distance against measurements calculated on screen. I don\'t know if possible but it would be very very useful.

The more I use it, the more I like it. Simple yet useful features, especially the 2 moveable markers that can be preset to a desired measure, or just slid along to literally pinpoint the points that you are measuring.
Douglas Garland 2020-05-18

Simple, accurate and user friendly. Incredible as there are no ads! Thank goodness. I had searched around for several ruler apps and this one met my requirements. I really enjoy using this app and highly recommend.
