Per-criterion

Content quality3.9 / 5

Like every marketplace, Preply has no curriculum of its own — content quality is whatever the tutor brings. Many Spanish tutors build a tailored lesson plan after the trial, and the platform nudges them to set goals and track progress, which gives Preply slightly more structure than a pure pay-as-you-go board. The ceiling is high (DELE prep, grammar plans, regional-dialect work), but the floor depends entirely on careful tutor selection and on the learner directing the sessions.

Instructor / method4.1 / 5

Preply's Spanish pool is enormous — over 13,000 tutors spanning certified teachers and native community tutors across Spain and Latin America. A well-chosen tutor is repeatedly named the single highest-leverage decision. The catch is vetting: reviewers note Preply does not control what or how tutors teach and not all tutors are certified, so the gap between an excellent teacher and a merely adequate one is real and falls on the learner to screen via trial lessons.

Value for money3.9 / 5

Spanish is one of Preply's deepest and cheapest markets — classes start around $3 and average roughly $15-16/hour, comparable to italki. Value is dented by two policies reviewers dislike: lessons are bought in packages (subscription credits) up front rather than one at a time, and tutors are not paid for the trial lesson. For committed weekly learners the per-lesson math is strong; for casual or irregular learners the credit model creates friction.

Retention & motivation4.0 / 5

The subscription/weekly-credit model is the most polarising feature, and it cuts both ways on retention. Learners who pre-commit to a recurring slot describe it as the most durable Spanish habit they built — committing to a schedule means flaking less. Learners with busy, rotating schedules find the same model strict, and several flagged auto-renewal and expiring credits as a drag. Net positive for habit formation, with real friction for irregular schedules.

Support3.6 / 5

Scheduling, messaging and tutor-matching are reported as smooth, and the trial-lesson flow is praised. The weak spot is billing and cancellation: the cancellation window is strict, and a recurring complaint across user reviews is being charged after cancelling or struggling to stop the subscription. This is the most-cited support frustration and the main reason this score sits below italki's.

Real-world fluency4.4 / 5

The clearest strength. Regular 1-on-1 conversation with a native Spanish speaker is the most direct route from app-bound recognition to real speaking, and learners describe twice-weekly sessions cementing concepts they had struggled with and raising confidence sharply. The format exposes gaps (preterite at speed, ser/estar, subjunctive) that apps never surface, and tutors adapt vocabulary to each learner's actual goals.

Content quality3.9 / 5

The French course now extends to upper-intermediate (B2) following a December 2025 expansion, and recent updates added more conversational dialogues and grammar tips. Vocabulary coverage is broad and the Stories feature adds useful context. But grammar is taught primarily through implicit pattern-matching rather than explanation, and reviewers flag a high proportion of impractical sentences in early levels.

Instructor / method3.5 / 5

There is no instructor. The method is gamified implicit learning — learners recognise patterns through repetition rather than being taught rules. For French beginners who primarily need vocabulary and exposure, the method works; for learners who need to understand French syntax and grammar logic, the absence of explanation is the app's central pedagogical weakness.

Value for money4.7 / 5

The core course is genuinely free, making it the best zero-cost entry point to French learning available. Duolingo Super (~$7/month) removes ads and adds unlimited hearts; reviewers largely agree this subscription does not fix the structural gaps, so the free tier is where most of the value sits.

Retention & motivation4.3 / 5

The streak system, daily reminders, XP leagues and personalised characters make Duolingo the most habit-forming language app available. Multiple reviewers report using it every day for years. The gamification that some critics find shallow is the exact feature that keeps learners coming back when other apps do not.

Real-world fluency2.9 / 5

This is the course's most consistent weakness. Reviewers across multiple sources agree that Duolingo teaches recognition, not production. Learners can read and recognise French reasonably well but struggle to speak it. Pronunciation feedback accepts rough output; native speakers speak faster and more connected than the app ever models; and conversation practice is not a feature.
