How do I earn profile pictures?

Why am I seeing ads?
Cleo is free to download and comes with a generous daily ad-free allowance — each day you get 3 modules and 3 quizzes completely free with no ads. Ads only appear once you've used your daily free quota, and they help us keep the app free for everyone. You can opt out of personalised ads at any time in your device settings.
