Forget fumbling for a physical tape measure—now your smartphone can do the job. The AR Ruler App, available on Google Play, is redefining how we take measurements by using augmented reality (AR) technology to measure distances, angles, and more—directly through your device’s camera.
Built by Grymala, the app has garnered over 10 million downloads, offering a practical tool for everyone from interior designers and construction workers to DIYers and students.
