Install the app from Google Play app or the Apple App Store, Search "Routechoices Tracker", by Raphael Stefanini.

Upon opening the app, it will display a device ID.

Before starting a event, click the "Start live GPS" button to start sharing the location of the phone with us. And when the event is over, Turn off the app with the "Stop live GPS" button.

Once the GPS signal is good, the device ID turns green and the app starts uploading its locations.

Ensure that GPS location provider with high accuracy is enabled in the system settings for the app and that GPS access is allowed all the time. If not, uploading GPS data will stop when screen goes to sleep.

Note: Google and Apple are trying to restrict background processes to give user better battery life, but it affects application like Routechoices Tracker which require persistent background execution. Common issues to check for:

• On recent versions of Android make sure that Routechoices Tracker has been added to battery optimization exceptions.
• Some Android vendors have their own battery optimization in addition to standard Android system. Make sure those are disabled or the app is added to exceptions.
• On iOS, make sure that in settings background execution is allowed and Routechoices Tracker has permission to always access location services.
• Also on iOS, ensure that the settings in "Settings > Privacy > Location Services > Routechoices Tracker" is set to "Always"
