The Little Green Button is available on Google Play - use the below button/QR to be redirected there.

Once you are on the Google Play page for the Little Green Button, press the Install button to start the download.



Once the download is completed, please tap the Open button to start the app, or start the LGB app from the launcher.


The app will launch and you will be presented with the first time setup wizard. Press Next to continue.


Select "Connect to your organisation". Click "Next" and you will then be asked to complete some information.



Please fill out your name and phone number. Both of these will be displayed on alerts that you send out, to help the receiver understand who sent out the alert. Press Next to continue.


You will now be asked to provide a Personal Pin. This is to be used when de-activating raised alerts (this feature can be switched off later, if preferred).



Press Next to continue. 


You will now be asked to either manually enter your Organisation activation code, or scan a QR code, in order to connect to your organisation. 






Your QR code can be found on your Little Green Button Management Site (see below screenshot). Please contact either your internal LGB administrator, or us at LGB support, if access is required. 


Note: You will be asked to allow access to your camera in order to scan the QR code. Little Green Button only uses your camera to scan the code during this activation process.





After completing this section, you will be asked to read and accept the terms, disclaimers and privacy statements. Once ticked, press continue.




Your app will initially show that although you are now connected to your organisation, you are not yet assigned to a particular group




Configuring Groups with the Mobile App


In order for the user of the Mobile App to join a group, this must be pre-configured in your My LGB portal.


To do so, an Admin user of the portal will need to navigate to the Configuration tab, and add the device and assign to a group. 


Please note that the device name can be found on your Device Locations report. The unique device name will change each time the app is either reinstalled, or the data wiped, and will therefore need to be re-added into the configuration.


Please see the Configuring Groups article for more detailed information on how to assign the Mobile device to a group(s).


Once added into the configuration, you will need to close and reload the app to pickup the changes. You will now have the option to select from the pre assigned groups, and a subsequent location. If the user is not static, they should select "Current Location" in order for colleagues to know their exact location.


Please note: This is a new feature included in the most recent version of the LGB app. Historically users have been able to select their own Group, however this has now been restricted to only groups that have been preassigned in your Configuration.


If you do not have any groups pre-configured, or if you choose to select "No Group", the app will use the device GPS to determine your location. You will need to allow the app access to your location, in your phone settings.


The initial setup of the app is now complete.
