There are over 300 language-learning apps on the market right now. Most of them promise fluency. Very few deliver it. We spent three months testing the top five English-learning apps from the perspective of a Latin American adult learner who needs real conversational ability — not just a streak counter.
Here's what we found.
What We Tested For
Every app was evaluated on five criteria:
- Speaking practice — Does the app make you actually talk?
- Feedback quality — Can it identify and correct your specific errors?
- Real-world relevance — Are the phrases useful in actual conversations?
- Engagement — Will you keep using it after week one?
- Price-to-value ratio — Is it worth the monthly cost?
1. Duolingo
Price: Free (Super plan: $12.99/month)
Duolingo remains the world's most downloaded language app. Its gamification is unmatched — XP points, leagues, and streaks keep millions coming back daily.
Pros:
- Addictive game mechanics
- Huge course library
- Free tier is genuinely usable
- Stories feature adds context
Cons:
- Minimal speaking practice in free tier
- Exercises focus heavily on translation, not production
- Error corrections are generic ("Wrong!") rather than specific
- Sentences often feel artificial ("The duck eats bread")
Best for: Complete beginners who need daily habit-building and vocabulary exposure.
Speaking score: 3/10
2. Babbel
Price: $14.95/month
Babbel takes a more structured, textbook-style approach. Lessons follow a curriculum designed by linguists, and the content feels more professional than Duolingo's.
Pros:
- Well-structured grammar progression
- Business English courses available
- Speech recognition for pronunciation
- Offline mode
Cons:
- Speech recognition is basic — accepts almost anything
- No real-time conversation practice
- Lessons can feel repetitive
- Limited free content
Best for: Intermediate learners who want grammar clarity and professional vocabulary.
Speaking score: 4/10
3. Rosetta Stone
Price: $11.99/month (or $179 lifetime)
The legacy brand of language learning. Rosetta Stone uses immersive, image-based learning without translation — you learn English in English.
Pros:
- Full immersion methodology
- TruAccent pronunciation engine is decent
- No translation crutch builds intuition
- Live tutoring sessions available (extra cost)
Cons:
- Feels dated compared to newer apps
- Progress is slow — lots of repetition
- Live tutoring is expensive and limited
- No AI-powered conversation partner
Best for: Patient learners who prefer immersive methods and have budget for live sessions.
Speaking score: 5/10
4. Busuu
Price: $13.99/month (Premium Plus)
Busuu's standout feature is its community correction system. Native speakers review your written and spoken exercises, giving human feedback.
Pros:
- Community corrections from native speakers
- CEFR-aligned curriculum
- Vocabulary review with spaced repetition
- Offline mode
Cons:
- Community feedback quality is inconsistent
- Speaking exercises are recorded, not real-time
- Limited advanced content
- App can feel cluttered
Best for: Learners who want human feedback and don't mind asynchronous practice.
Speaking score: 5/10
5. VOZA
Price: Free tier available (Pro plans from $9.99/month)
VOZA takes a fundamentally different approach. Instead of lessons and exercises, it puts you into real conversations from day one using voice AI. You speak, the AI responds naturally, and you get instant feedback on pronunciation, grammar, and fluency.
Pros:
- Speaking-first methodology — you talk from minute one
- Real-time AI conversation partner available 24/7
- Instant, specific pronunciation feedback (not just "try again")
- Scenarios based on real life: job interviews, ordering food, dating, business meetings
- Native Spanish and Portuguese interface for Latin American learners
- Tracks fluency metrics over time (words per minute, filler word reduction, error patterns)
Cons:
- Less focus on reading/writing skills
- Requires microphone access
- Advanced grammar explanations are lighter than Babbel
Best for: Anyone who wants to actually speak English confidently — especially Latin American learners who need conversation practice without the anxiety of a live tutor.
Speaking score: 9/10
The Verdict
Here's the uncomfortable truth about most language apps: they teach you about English without making you speak English. You can have a 500-day streak and still freeze when someone asks you a question in real life.
| App | Speaking | Grammar | Value | Real-World Use | |-----|----------|---------|-------|----------------| | Duolingo | 3/10 | 6/10 | 9/10 | 4/10 | | Babbel | 4/10 | 8/10 | 6/10 | 6/10 | | Rosetta Stone | 5/10 | 5/10 | 5/10 | 5/10 | | Busuu | 5/10 | 7/10 | 6/10 | 6/10 | | VOZA | 9/10 | 6/10 | 8/10 | 9/10 |
Our Recommendation
If your goal is to speak English — to hold conversations, nail interviews, and stop freezing in real situations — the choice is clear. VOZA was built specifically for the moment your mouth needs to produce English, not just your eyes.
That said, apps work best in combination. Use Duolingo for daily vocabulary habit-building, Babbel for grammar deep-dives, and VOZA for the speaking practice that actually builds fluency.
