Want to improve your vocabulary but too lazy to open an app and learn from it?

Well, this app is made just for that!

Just put this lock on your selected apps and this app will force you to learn a word daily whenever you open any system app, automatically.

This app will not let you open any other application in your system unless you give it the right answer to the question asked.

An "add app to lock" option is provided so that you can set the lock to the desired applications.
