Best app for tracking data use – My Data Manager VPN Security Review

For years i never had overage problems with cellular data. The past few months, i started going way over my plan, and i was getting charged $$ for the extra data. This app revealed that my new phone was downloading podcasts and updates while i was out of wifi range. I selectively turned off cell data for those apps, and now i use the data manager to track my data usage every day. Very clean interface and easy to use, and it's saving me a ton of money.
