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 points suit some learners while stressing others. Zonlo has no streaks at all. It is 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, points, and Leagues are built to pull you back every single day, 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 people using it every month. Its short, playful lessons and famously good first few days make it the default first stop for new learners, and its free tier is genuinely generous.
It is excellent at what it was built for: building a daily habit and a base of vocabulary and grammar. Speaking, though, is mostly repeating sentences, and live conversation with “Lily” sits behind the top Max tier.
Where Duolingo genuinely shines
- The best free tier around
- Built to become a habit, and the first few days are outstanding
- Lots of languages, Japanese included
- Great for building vocabulary and grammar basics
Where it is more limited
- Speaking practice is thin, mostly repeating sentences
- Streaks, points, and Leagues create daily pressure some learners dislike
- The 2025 “energy” system drew backlash for limiting free lessons
- Being good at the app does not always transfer to a real conversation
