6 apps compared
The usual reason for leaving Duolingo is not that it is bad but that a long streak has not produced someone who can hold a conversation. What you move to depends on which part is missing — and it is worth saying that Duolingo still beats every app here at one thing.

Short answer
If you want a complete practice loop with speaking and reading rather than a streak, NativePal is the closest single-app replacement. Choose Babbel for properly explained grammar, Pimsleur for hands-free speaking, Anki for retention, and italki or HelloTalk if what you actually need is a person to talk to. Duolingo still wins on one thing: nothing else is as good at making you show up daily.
1. Best all-round practice loop
The only app here that covers levelled reading, vocabulary with spaced repetition, pronunciation scored down to individual sounds, and conversation in one place. Free to start with a daily allowance.
Where it falls short: If you only want one narrow thing — pure audio, or pure flashcards — a specialist below will do that one thing better.
2. Best for structured grammar
Courses written by linguists rather than generated, with grammar explained properly instead of inferred from examples.
Where it falls short: Only covers around 14 languages, and the course ends well short of advanced.
3. Best for hands-free audio
A disciplined audio method that makes you speak aloud from the first lesson. Genuinely usable while driving, walking or cooking, which is time most people cannot otherwise study in.
Where it falls short: Very little reading, and the fixed lesson order means you cannot skip ahead to what you actually need.
4. Best for raw vocabulary retention
Free, open source, and the best spaced-repetition scheduling available anywhere. If your problem is that words do not stick, this is the tool.
Where it falls short: It is a flashcard engine, not a course: no lessons, no speaking practice, no curriculum, and you have to build or download decks yourself.
5. Best for lessons with a real teacher
A marketplace of human tutors, which no AI matches for catching the thing you did not know you were doing wrong. A good teacher beats any app, including NativePal.
Where it falls short: You pay per lesson and have to schedule them, so it works best as a weekly anchor rather than daily practice.
6. Best for community corrections
Submit written and spoken exercises and get them corrected by native speakers, on CEFR-aligned courses with optional certificates.
Where it falls short: Correction turnaround depends on volunteers, so it is not instant feedback.
Because tapping the right tile and producing a sentence out loud are different skills, and gamified apps optimise the first. Streaks measure attendance rather than ability. Fixing it means practice that makes you generate language — speaking aloud, writing without prompts, reading things you have not been pre-taught.
No, and it is genuinely the best in the category at habit formation, which is the failure point for most learners. The problem is treating it as complete. Many people keep the streak going and add a second app for speaking and reading.
Busuu, if you want the same course-and-lesson shape with CEFR alignment and native-speaker corrections. NativePal, if you want to keep the daily-habit framing but spend it on reading at your level and scored speaking practice rather than translation exercises.
Two works well: one main app for structured daily practice and one to plug a specific gap, usually Anki for retention or italki for conversation. Three or more usually means none of them gets enough attention to matter.
