User Reviews

Users praise the app for its simple, clean UI and usefulness as a quick measurement tool. It’s often described as easy to use and generally reliable for basic tasks. However, several reviews complain about intrusive ads, insufficient guidance on how to measure, and a lack of landscape orientation support. A minority still finds it valuable, especially within the developer’s suite of quick-access tools, but ad fatigue and instructional gaps hinder consistent satisfaction.

The date setting in the app is not correct, it is set for a month in advance. today's date is 05/22/26, and the date showing in the app is 06/22/26... This is unchangeable.
