Yeah I have been using this for more than year and s doing well.
The best part is its able to prevent force stop which is not found in many security apps and because of this security breach happens that too frequently in college life
Also now it has got a feature to save photos, videos directly in the app.Also there is one more feature "random keyboard " in which the numbers interchange and others find it difficult to figure out .
even cover feature which appears like fake screens and confuses whose who try to steal your info.
only irritating thing is settings are locked everytime.
