Treecampus built its free English learning app around a simple frustration: most "free" apps quietly lock the good content behind a subscription after the first few lessons. This one doesn't. The app focuses on practical spoken English — pronunciation drills, everyday conversation scenarios, and confidence-building exercises — rather than gamified streaks that distract from actual learning. Built and maintained by a non-profit, the app stays free permanently, not just during a trial period. It's designed for learners who want a straightforward way to practice speaking English without a paywall showing up when they're finally making progress.
