Mic & Pose boosted app adoption 6X by delivering lessons through WhatsApp instead of fighting push notification fatigue

About Mic & Pose

Mic & Pose is a language learning platform based in Colombia that helps Spanish-speaking users build English proficiency through interactive, mobile-first experiences. The company combines structured curriculum with conversational practice, targeting working professionals and students across Latin America who need English skills for career advancement. Operating in a region where WhatsApp is the dominant communication channel, Mic & Pose recognized early that meeting learners where they already spend their time was essential to sustained engagement.

The Challenge

Mic & Pose had the same problem every ed-tech company faces: users download the app, try it once, and disappear. Push notifications were ignored. Email reminders did not work. In Colombia, WhatsApp is how people communicate, but Mic & Pose had no way to reach users there.

What They Did

Results

6X boost in app adoption. Daily lesson completion rates soared because reminders came through the one channel nobody ignores. The AI call feature became a differentiator. Users loved getting "called" by their language coach for practice. The loop of call, assessment, tips via message created personalized learning that kept people coming back day after day.

• 6X: App adoption boost
• Daily: Lesson reminders via WhatsApp
• AI Calls: Pronunciation assessment

“Stop asking users to come to your app. Bring your app to where they already are. 6X adoption came from meeting learners on WhatsApp, not fighting to pull them back.”
