Add focus streaks with an animated flame and gemstone rewards at milestones

David BarnardWe are coming up on time. But there's three questions I've been asking every guest who'd come on. Let's get to that. The first one is, what's your biggest win of the last year? The experiment that performed way better than expected, something you implemented, what's your biggest win?

Kenneth SchlenkerThe biggest win is streaks. Believe it or not, we have our own way of counting streaks. But essentially, the more you focus with Opal, the more you get a streak.

Kenneth SchlenkerWe've also put a lot of effort, speaking of brand and making this beautiful. The streak is represented by this small frame, which is not like an emoji flame, but actually an animated flame. You can get beautiful Opal gemstones once you reach different streak milestones. That's, I would say, the biggest win in the last year to improve retention and growth.

David BarnardYeah, that's so cool. Streaks don't work for a lot of apps. So many apps try streaks. But it's great to hear. It makes sense that it's landing for Opal. What was your biggest fail of the past year?
