Case Study: Chatterbug Achieves +311% Signups with App Radar's UGC-Driven User Acquisition

How language learning app scaled User Acquisition through UGC

Chatterbug, a language learning app, partnered with App Radar to launch a new mobile app on Google Play and the Apple App Store in 2021. Their challenge was breaking into the highly competitive education category and reaching the top 10 against established rivals with much larger marketing budgets.

App Radar supported Chatterbug with User Acquisition, ASO, creative A/B testing, and mobile measurement partner implementation across channels like Apple Search Ads, Google Ads, Facebook, TikTok, and Snapchat. By scaling UGC-based influencer creatives, optimizing campaign structure, and reallocating spend to the best-performing audiences and markets, App Radar helped Chatterbug achieve +311% signup growth in 6 months, a 20% increase in 1-month retention, and a 41% reduction in CPI.
