Yes! Boomr's mobile app is functional even when your phone or tablet doesn't have an Internet connection. You'll know when your app isn't connected when there is an orange shows on the screen that says "No Internet Connection" - this means your app is in Offline Mode.
While some of the functionality of the mobile app is restricted when in Offline Mode you can still track time by checking in/out for work and taking breaks. To do this, click on the green Track Time button as you normally would and select the option to "Check in to a new shift". All shifts that are tracked in Offline Mode will be synced with your account when your device reconnects to the Internet.
