Google's Datally app launched last year to help Android users keep tabs on their phone's data usage, and today the app is getting a couple of new features.

First up, the Emergency Bank saves some of your data in case you need it later. Just enter your data balance into the app and then how much data you'd like to save for emergencies. Datally will block your apps from using data once you reach your emergency data allownace. You can decide when and how to use your emergency bank data.

And then there's Bedtime Mode. When enabled, Bedtime Mode will turn off all of your phone's data usage at night, ensuring that your apps aren't using up data in the background while you're sleeping.

These new Google Datally features are rolling out today.
