Review the Apps
Pay attention to the names of the apps listed. Look for any words that are secretive such as “secret” “vault” “decoy” “spy” “safe” “private”
Test your skill, there is an app of concern in the picture, can you find it?
Pay Attention the Size of Apps
Some apps might attempt to hide their name and not include secretive names. Look at the size of apps and compare against others, and ask yourself, should a simple app like a calculator be the same size of apps like games?
