iRuler

iRuler is a compact virtual ruler app that displays a ruler on the screen for quick length measurements when a physical ruler is not available. Its simple, intuitive interface supports switching between inches and centimeters, making it suitable for designers, students and everyday emergency measuring tasks. As a classic small utility once popular in early iOS communities, it focuses on straightforward, practical measurement rather than complex features. It is a handy choice for users who need a basic measuring tool on their device. Interested users are welcome to download and install it from iOSIPA Software Network.
