Round 1: How they teach
Duolingo teaches through short, game-like lessons with streaks and leagues. Lessons cover speaking, reading, listening and writing. Explain My Answer, which gives AI grammar feedback, has been free since January 1, 2026, and the Practice Hub has been free since February 18, 2026.
Rosetta Stone teaches through what it calls Dynamic Immersion. Its blog says everything is presented in your new language, most activities include no instructions in your current language, and grammar is learned by reading examples and listening to native speakers, all without translations. Its method page says grammar is taught in context.
Takeaway: if you want to learn with no translations at all, Rosetta Stone is designed that way. If you want grammar feedback in English, Duolingo’s free Explain My Answer helps.
Round 2: How far can each take you?
Duolingo announced on April 22, 2026 that nine courses (English, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Chinese) now teach through B2, the level of an independent user. Rosetta Stone’s consumer pages describe units, lessons and activities on a Learning Path but do not publish CEFR levels, a unit count or an end point, so it is hard to compare its ceiling with Duolingo’s.
Takeaway: for a clear, published ceiling, Duolingo is easier to judge. Check Rosetta Stone’s level details for your language before you subscribe.
Round 3: Speaking practice
- Duolingo: speaking exercises in lessons, a free Practice Hub with Speak practice, and, with Max, AI Video Call (one to three minutes) and Roleplay.
- Rosetta Stone: TruAccent compares your pronunciation with examples from native speakers and tells you how well you said it, in nearly every lesson, plus Chat Missions for conversation practice. Live tutoring is a paid add-on, for example five 30-minute sessions for $279 or ten for $399 for US subscribers.
Takeaway: Rosetta Stone builds pronunciation feedback into the core lessons, while Duolingo’s deepest speaking features sit behind Max.
Round 4: Price
| Plan | Approximate US cost per year |
|---|---|
| Duolingo Free | $0 |
| Duolingo Super | About $96 to $120 |
| Rosetta Stone, yearly plan | $159 |
| Duolingo Max (if still offered) | About $168 |
| Rosetta Stone, paying monthly | About $240 |
Duolingo’s prices come from the US App Store listing and independent trackers, because it does not publish a fixed price sheet. Rosetta Stone’s come from its buy page. Rosetta Stone’s terms say plans renew at the full retail price, and its lifetime plan is described as a limited offer that may stop being sold at any time.
Takeaway: Duolingo is cheaper unless you buy Max, and it is the only one with a permanent free tier.
Round 5: Ratings and evidence
Both have low Trustpilot scores for different reasons. Duolingo’s reviewers cite unexpected annual charges after a trial, crashes and poor support. Rosetta Stone’s older reviews cite the end of lifetime access, forced subscriptions and unresponsive support, and only 35 of its reviews are from the last year. Both have high scores on the App Store from active users.
On evidence, Duolingo’s research is mixed: several studies were funded by Duolingo, and an independent 2023 review found very little conclusive evidence. Rosetta Stone cites a 2019 report, funded by the company, in which 13 hours of Spanish practice matched a college semester for 143 learners.
