Per-criterion
The course is widely praised for its writing-system tool that teaches the Cyrillic alphabet through tracing and sound-association exercises, and reviewers at Duoplanet, Cherish Study and Duolingo Guides single this out as the single best part of the Russian tree. Vocabulary building and reading practice are strong, and the gamified lesson flow keeps beginners moving. The consensus weakness is depth: the Russian course is described by Duoplanet as "really short" with "nowhere near as much content" as French, Spanish or German, and it gives exposure to grammar without ever explaining it. Cases, conjugations and aspect — the hard core of Russian grammar — are left for learners to figure out elsewhere.
There is no human instructor; Duolingo's Russian course is algorithm-driven with a discovery-based teaching model where learners infer rules from repeated phrases rather than being taught them. Reviewers describe this as a feature for casual exposure and a liability for a case-heavy language. The forum user Flin captured the frustration directly, calling every fill-in-the-word exercise "a gamble" because the app never clarifies whether the answer depends on tense, gender, plurality or case. The animated characters and streak mechanics substitute encouragement for instruction.
The core course is completely free, and reviewers universally treat this as its strongest argument. LingoDeer's reviewer notes Duolingo "makes language learning available to the majority" and the free tier is enough to learn the alphabet, basic vocabulary and beginner phrases without spending anything. The optional Super subscription (roughly 7-13 USD per month) removes ads and adds practice features but does not fix the structural grammar and speaking gaps, so most reviewers see little reason to pay specifically for the Russian course.
Gamification is the area where reviewers are most consistently positive. Points, levels, leaderboards and streaks make daily practice genuinely habit-forming — Duolingo Guides calls the achievement system "a powerful tool for language learning motivation," and the Satanaya review credits "20 minutes every morning for months" with teaching more than sporadic bursts. The flip side is that streak-chasing can reward going through the motions rather than deep learning, and several reviewers note the short Russian tree means committed learners run out of content.
Support is minimal. There is no teacher, no mentorship and no structured grammar reference inside the course; the old sentence-discussion forums have been retired, leaving learners to rely on third-party blogs, the wider community and external grammar resources when they get stuck. For a language as grammatically demanding as Russian, multiple reviewers explicitly recommend pairing Duolingo with a dedicated grammar resource or a tutor, which tells you how little the app itself supports learners past the basics.
Reviewers agree the course delivers real, usable beginner ability: after finishing you can read signs, menus and simple texts, and the Satanaya reviewer notes "even knowing a little Russian can make a huge difference when travelling across parts of the former Soviet world." The hard ceiling is conversation. The app focuses on reading and listening and, in reviewers' words, "doesn't really teach you how to speak naturally or confidently," capping most learners around A2. For travel survival Russian it is genuinely applicable; for real spoken fluency it is a foundation, not a finish line.
Preply is a marketplace, not a curriculum — "Preply doesn't use standardized curricula or textbooks", as one reviewer puts it, so content is whatever the tutor builds after your trial. For French specifically the platform layers on useful scaffolding: a placement test, a record-a-message-to-a-tutor feature, and a library of vocabulary exercises, tests and quizzes. The ceiling is high (DELF/DALF prep, pronunciation and gender-agreement drills, conversational fluency), but the floor depends entirely on directing your own sessions.
The French tutor pool is enormous and well-rated — beginner French tutors average 4.93/5 across 65,000+ verified reviews on Preply's own listing. A well-chosen native tutor giving real-time feedback on pronunciation and sentence structure is repeatedly named the platform's strongest feature. The catch is vetting: "the quality of lessons can vary widely because some tutors may not have formal teaching qualifications", so screening via trial lessons falls on the learner.
French lessons span roughly $5-40/hr (averaging $10-15), one of the cheaper ways to get genuine 1-on-1 speaking time. Value is dented by the commission and pricing structure: tutors are unpaid for the trial, Preply takes 100% commission on a new student's first lesson then 18-33% after, and several learners report prices "start to increase after a few sessions". Strong math for committed weekly learners; weaker for casual ones.
"Project" here means the lesson and learning experience itself. Learners consistently praise the personalised, goal-driven format and the convenience of jumping into a video call from a phone. The French placement test and practice tools give the experience more shape than a pure pay-as-you-go board. Friction comes from the classroom app — Reddit users in 2026 report chat glitches and limited mobile capabilities — and from booking rigidity.
This is Preply French's clearest strength. Live conversation with a native speaker, immediate correction of pronunciation, gender agreement and idiom, and lessons tailored to a job interview or travel goal translate directly into usable speaking ability. Preply's 2025 study claims learners taking 24+ lessons over 12 weeks progress 3x faster than typical timelines; even discounting the marketing, the speaking-first format is what self-study apps cannot replicate.
