Top 6 Apps for Monitoring Mobile Data Usage

Avoid excess data usage charges on your smartphone or tablet.

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.

  • Historical usage reports
  • Ability to set thresholds and receive notifications for exceeded limits
  • Predicting when you will go over your limits and setting daily quotas
