You
Silicon Valley learned how to keep you coming back. Streaks, rewards and that little urge for just a bit more turned your attention into their business.
What if that urge brought you back to a book? Ávido puts challenges, streaks and rewards to work for your reading. Each session adds progress, XP and a reason to pick up where you left off.
