The app can be downloaded from the Apple App Store and the Google Play Store.
The app is available only for Android and iOS smartphones. Other operating systems are not supported.
Supported Android devices: Bluetooth®-enabled smartphones from Android 6.
Supported iOS devices: iPhone (from 5s).
Tablets are not supported.
Go to the app settings to see which languages the app is available in.
The app can be connected to the GLL3-330C Professional and the GLL3-330CG Professional.
First, check that Bluetooth® is activated on both your tool and your smartphone and that the devices are within range. Neither of the devices must be connected to any other Bluetooth® device. In the app, you can tap on the Bluetooth® symbol to establish a connection between the laser and the smartphone. Please note that this connection must always be established via the app, not via the settings menu on your smartphone.
No. It can only control one tool at a time.
The typical range is approximately 10 m (30 ft), depending on the on-site conditions (obstacles, sunlight, etc.). In optimum conditions, the range can be up to approximately 30 m (100 ft).
If the tool has been connected to the app before, it will be automatically detected when it is reconnected as long as the app is open on the smartphone, Bluetooth® is activated on both devices and the devices are within range.

This function allows you to select three different profiles:
1) Maximum laser visibility (reduces the battery runtime)
2) Balanced profile (average laser visibility, average battery runtime)
3) Maximum battery runtime (reduces the laser visibility)
In this function, you can see which of the three following events has triggered a calibration warning:
– The recommended calibration check interval (every 12 months) has passed.
– The line laser was outside the permitted storage temperature (between -20 °C (-4° F) and +70 °C (158° F)).
– The measuring tool was subjected to a strong shock (e.g. impact with the ground after being dropped).
The app shows when one of these events occurred and provides information on checking the leveling accuracy.
If your tool was manufactured after 11/2018, you can switch your tool's BLUEHOUND function on and off. To use BLUEHOUND, you need to download the BLUEHOUND app from the App Store/Google Play. Please visit www.bosch-professional.com for more information.
Thanks to hands-free operation via your smartphone, you no longer have to worry about shaking the laser line when trying to make manual adjustments, meaning that you don't have to readjust the laser.
The green laser beam is particularly useful in bright working environments, such as near to a window, because its visibility is four times greater.
The app allows you to adjust the visibility of the laser beam. This means that you can, for example, minimise the laser brightness so that the battery runtime is increased.
