RIDGID Sketch is a free Android application developed by RIDGID Software Solutions that allows you to measure and communicate various dimensions on your projects. This app can be used on its own or in conjunction with a RIDGID LM-400 Laser Distance Meter, which connects to your device via Bluetooth and provides precise distance measurements. With RIDGID Sketch, you can work in both drawing mode and photo overlay mode, enabling you to develop accurate room plans or annotate measurements within a picture.

The app is straightforward and easy to use, with a clean interface that allows you to quickly switch between drawing and photo modes. In drawing mode, you can create precise plans by drawing lines and shapes directly on the screen. In photo overlay mode, you can take a picture of the space you're working on and overlay measurements and annotations on top of it. Overall, RIDGID Sketch is a handy tool for anyone who needs to take precise measurements and annotate plans on the go.
