MyB Achieves 3x Revenue Growth and a 210% ARPDAU Increase with adjoe’s Playtime

MyB is a fast-growing Korean mobile app that has scaled quickly since launching just a year ago by 1SelfWorld. Built on a patented hyper-personalization technology, the app delivers tailored quizzes and personalized rewards.

This model does two things at once: it answers the growing need for precise targeting beyond traditional ad identifiers and gives users a reward experience that reflects their own preferences. By 2025, MyB had already passed the one-million-subscriber mark. As the team grew the user base and refined its personalization engine, they began looking for new ways to increase revenue without losing their focus on preference-driven engagement.

With a rapidly expanding audience, MyB needed new monetization streams but wanted to avoid the usual trade-off: more revenue at the cost of intrusive ads and unhappy users.

Any new revenue driver had to stay true to the app’s core promise—fun, personalized interactions that match each user’s tastes.

As demand for more engaging experiences rose on both the user and advertiser side, MyB, whose model is built on personalization and user-first product design, started searching for a monetization partner that could boost retention, daily activity, and ARPDAU.

In March 2025, MyB integrated adjoe’s Playtime, a time- and event-based rewarded ad format that invites users to discover new mobile games and spend time playing them. The format fit naturally with MyB’s existing rewards setup.

Because Playtime rewards users either for their in-app playtime or for hitting in-game milestones, users can choose both the game and the reward path that suit them best. For MyB, this became a direct extension of the experience they were already offering.

The approach clicked quickly with their audience. Within a few months, Playtime had settled in as a regular part of the app’s ecosystem—supporting stronger monetization and driving more frequent, richer daily engagement.

Just four months after the integration, the effect was clear. By July 2025, MyB’s revenue was three times higher than in February, showing how strongly Playtime contributed to overall monetization.

ARPDAU grew by 210%, supported by deeper, longer user engagement triggered by event-based rewards. MyB also recorded a 31% increase in “power users”—people who log in every day for a full month—an important signal of long-term retention and habit formation.

Playtime increased both user enjoyment and business results while staying aligned with MyB’s mission to deliver preference-based rewards. On an average day, around 10% of MyB’s entire user base engages with Playtime, confirming its role as a key driver of in-app activity and value.

After the success of the initial Playtime rollout, MyB plans to make the partnership with adjoe a bigger part of its monetization strategy. The next step is to push personalization even further by finding more ways to match user preferences with specific rewarded experiences.

As MyB continues to grow its community, the team sees Playtime’s event-based reward model as a core lever for future revenue, retention, and user satisfaction.
