Data-savings app Opera Max has just been updated. This app has been helping a lot of Android users conserve their precious data by managing and monitoring data usage. This app can help extend data plan savings, block data hogging apps, and offer real-time, daily, or monthly usage statistics. This new version now tracks data usage on WiFi networks. This makes sense since about 80% of usage on a device is on WiFi and Opera Max users have been requesting for such feature.
