The Bosch Leveling Remote app enables you to conveniently control your Bosch Professional leveling tool via Bluetooth® from your smartphone.
Using the app, you can control the laser remotely without having to even touch it, thereby increasing productivity and efficiency in your daily leveling tasks.
The app can be connected to all Bosch Professional leveling tools (line lasers, combi lasers and rotary lasers) which contain a "C" in the name, for example:

• GCL 2-50 C/CG Professional
• GCL100-80C/CG Professional
• GLL 3-80 C/CG Professional
• GLL3-330C/CG Professional
• GRL 600 CHV Professional
• GRL 650 CHVG Professional
• GRL4000-80CHV Professional
• GRL4000-80CH Professional
• GRL4000-90CHVG Professional

Main functions when using a GCL or GLL device:
• Conveniently control your combi / line laser by setting the operating mode, turning your tool into standby or changing the laser intensity to optimize the laser visibility or battery runtime.
• Monitor your tool by checking the battery and device status via the app.
• Check for potential external influences and calibration intervals to ensure the accuracy of your line laser (available for selected tools)

Main functions when using a GRL device:
• Easily control all main functions of your rotary laser such as setting slope, modifying the rotation speed, or putting your device into standby mode
• Benefit from app-only features like setting up the partial projection (Mask Mode) or creation of Profiles to save and apply the setting you need
• Check the accuracy of your tool and have it corrected automatically

We are very pleased to receive your feedback and improvement suggestions for our application. Simply contact us via app.support@de.bosch.com and let us know if you have any wishes or problems – we are happy to help you!
