Top 5 Apps for Monitoring Mobile Data Usage

Unless you have an unlimited data plan for your smartphone or tablet, you have a service plan that limits the amount of data you can transfer online every billing cycle. To avoid exceeding these limits and incurring excess billing charges, monitor data usage on a smartphone or tablet using one of these popular apps. Some of the apps are free; others charge a small fee.

The Data Usage app is easy to install and uses theme colors that change to reflect current usage status. The app includes all the essential features of a data monitoring system:

The ability to track over time periods that match a user's billing cycles

Historical usage reports
Ability to set thresholds and receive notifications for exceeded limits
