An honest comparison
Zonlo vs Duolingo: which is better for speaking practice?
Duolingo is the most popular way to build a daily language habit, with an excellent free tier for vocabulary and grammar. Its speaking practice is thin, and its streaks and XP suit some learners but stress others. Zonlo has no streaks, just private speaking rehearsal for a real conversation you have coming up.
Duolingo is the world's most popular way to build a daily language habit, and its free tier is genuinely excellent for vocabulary and grammar basics. But its speaking practice is thin, and its streaks, XP, and Leagues are designed to maximize daily engagement, which some learners find motivating and others find stressful. Zonlo takes the opposite approach: no streaks, no points, no pressure, just private speaking rehearsal for a real conversation you have coming up. Use Duolingo to learn the words; use Zonlo to walk into the room ready to say them.

What is Duolingo?
Duolingo is the most recognizable language app in the world, with well over 130 million monthly active users. Its bite-sized, gamified lessons and famously good onboarding make it the default first stop for new learners, and its free tier is genuinely generous.
It is excellent at what it is designed for: building a daily habit and a base of vocabulary and grammar. Speaking, though, is mostly sentence repetition, and live conversation with the “Lily” video call sits behind the top Max tier.
Where Duolingo genuinely shines
- The best free tier in the category
- Habit-forming by design, with outstanding onboarding
- Broad language coverage, including Japanese
- Great for building vocabulary and grammar basics
Where it's more limited
- Speaking practice is thin, mostly repeating sentences
- Streaks, XP, and Leagues create daily pressure some learners dislike
- The 2025 “energy” system drew backlash for limiting free lessons
- App fluency does not always transfer to a real conversation
