Get the Tick

This app helps you to improve your English and have fun at the same time. The app looks like a calendar. When you click on a date, you get the task. Every day there's something new waiting for you in the app:
- a riddle;
- a new collocation/idiom with its meaning and an example of its usage;
- a joke to lift your spirits.
When you complete the task, you get the tick. Can you get them all?
Enjoy your experience with the app!
