an actual ruler says this app is off by at least 10% in metric and almost 15% in obsolete US measurements, no way to calibrate it

Developer Response

Thanks for your feedback. Calibration is available in Settings and only needs to be done once for the best accuracy. We recently redesigned the calibration screen with a step-by-step guide to make it much easier. Please give it a try and consider updating your rating if it helps.

v2.2

Used thier bubble level, like it, so i tried this app. I've thought in the past i would like something like this before. It is almost perfect for what it is, simple does basically one thing but does it well. So tired of scammy subscription apps. this is not one. A low one time price for somthing that does its job so well free i dont need the pro version. But becuse its does it well, the price is reasonable i wanted to support the creaters. Bought both apps, 11/10 recommend this app

The ruler is not correct!!!! Totally wrong.

Developer Response

Hi, the ruler is drawn based on device-provided screen data, which may vary b/w devices. For accurate results, a one-time calibration is required. Please calibrate from settings using a real ruler or card. If it works well after that, please consider updating your rating and even share your calibration coefficient to help others using same device.
