The website basically shows how much data some apps can consume, and compares it against some of the data plans provided by the carriers in the US. They also teach consumers to switch to WiFi services whenever available, and how to adjust app settings to prevent it from consuming more data than it should. Like we said this information is probably more suited to the less tech savvy, but for those still grandfathering unlimited data plans or for those who know their way around a smartphone, well we suppose this information is probably known, but some of it might be useful anyway. For those who know someone who might have gotten a smartphone for the first time, like an elderly relative, Know My App could be a good place to start.
