Distilled from 750 posts on blog.duolingo.com plus the Duolingo Handbook and Design System. Start at the /duolingo router; design and UI craft routes out to design-engineering.

How to cause the next session to start — where the reminder lives, when you have earned the right to ask for notification permission, what an ambient widget or lock-screen surface should show, how to attach a new behaviour to a cue the user already fires, how large your lapsed cohort really is, and what a returning user should see first. Use this when someone says our opt-in rate is terrible, where should the reminder go, users install and never come back, build a win-back flow, reactivation campaign, how do I measure resurrected users, should we ship a widget, people quit halfway through, our push notifications get ignored, how do we get them back without nagging, or what do we show a user who has been gone two months.
