What a human tutor does that an app can't
A good human tutor can make informed judgement calls about work that has no single correct answer. They can also notice when your confusion needs several rounds of explanation rather than another correction.
That doesn't mean every learner needs weekly private lessons. It means tutors are most valuable when you give them work that genuinely benefits from human attention.
Exam coaching
italki says its professional tutors are certified teachers with formal training, while Preply promises "the structure, accountability, and human connection of real teachers". Those strengths matter when an examination has a detailed rubric and strict timing.
A tutor can read the examiner's criteria, run a timed mock speaking test and tell you where your answer lost marks. They can also mark an essay against the examination's writing requirements. This is more specific than correcting everyday grammar.
Exam preparation is one of italki's listed course options. Its professional tutors offer structured lessons with prepared materials covering grammar, vocabulary and exam preparation. Teachers tailor lessons from A1 to C2, in booked sessions of 30, 45, 60 or 90 minutes.
Preply tutors also customise lessons for examinations, careers and pronunciation. Its trial lessons last 25 or 50 minutes, followed by subscriptions covering 1 to 5 hours each week.
The cost makes targeted use sensible. italki says online Japanese lessons typically cost around $15 to $60 an hour as of September 2026. Preply says Japanese lessons start from around $4, with an average of around $19, as of September 2026.
Use Lingrow daily for speaking volume, then pay a tutor for a few precise jobs. For example, practise oral answers in the app before asking a tutor to time and score a full mock examination.
Accountability
A booked slot creates a simple form of pressure. Another person expects you to arrive, complete the work and explain what you practised since the previous lesson.
That can help if you regularly intend to study but keep postponing it. A tutor can set a task on Monday, ask about it on Friday and adjust the next lesson around the result.
This accountability comes with scheduling and payment systems. Recent App Store reviews of both tutor platforms praise individual teachers but mention problems with booking, payments and customer support. Recent Preply reviews also mention subscriptions where unused lessons expire after 28 days.
Human accountability is useful, but it isn't the only way to build consistency. If you already practise whenever a spare 20 minutes appears, regular app use may give you enough structure without a fixed appointment.
Cultural nuance
Some language questions aren't really about grammar. A sentence can be correct but sound rude in a work email. A direct translation can also be too formal, too casual or simply odd for the relationship involved.
A tutor can discuss the people, setting and possible consequences. For example, you might ask how formally to address a boss, what to bring to a colleague's home or how to soften a request to a client.
A person can also answer an unusual question across several turns and adapt the explanation to your first language. That matters when the answer depends on tone, social expectations and several possible readings.
Apps can prepare you for common situations, but human judgement is useful when the stakes are personal. Bring a real example to a tutor, ask why one version fits better, then practise similar conversations in Lingrow.
Writing correction
Long writing often needs more than sentence-level corrections. A cover letter, university application or business email chain has a purpose, an audience and a tone that must remain consistent throughout.
italki lists creative writing and business courses as well as grammar lessons. A tutor working in those areas can explain why a paragraph feels too direct, why an argument is unclear or why a closing doesn't suit the reader.
For example, you could ask a tutor to review a cover letter for a particular role. They can consider the complete document, question what you meant and suggest changes that preserve your own voice.
Use this service for writing that matters. Daily messages, short answers and speaking mistakes can stay in the app, leaving paid tutor time for longer texts and difficult decisions.
What an app does that a tutor can't
Human tutors have limited calendars, and every lesson has a start and finish. An app is better suited to frequent practice because it can be available whenever you find a few minutes.
Lingrow combines voice conversations, guided teaching, feedback and vocabulary review in one subscription with a free trial. It's currently available on iOS only.
Any hour
You can open Lingrow at 11 pm before a trip, practise for five minutes in a queue or speak during an unexpected gap. There are no lessons to book and no time zones to coordinate.
Suppose you're flying the next morning. You can rehearse ordering coffee, using the metro and asking for directions that evening, then repeat one situation while waiting to leave.
Lingrow includes 350+ real-life scenarios across 15 languages. They cover travel, work, interviews, dating and casual conversations, with beginner, intermediate and advanced levels. Korean is the most developed language.
The app also has 100+ guided lessons. An AI tutor explains words, phrases and grammar on an interactive whiteboard, answers your questions, then uses the material in a short roleplay.
No judgement
Speaking practice can feel uncomfortable when another person is waiting for your answer. That discomfort can reduce how often you try a difficult sentence.
With Lingrow, you can say "I'd like a table for two" fifteen times. Nobody sighs, becomes impatient or needs to move to the next lesson activity.
This matters most when you know what you want to say but can't yet say it smoothly. You can restart and make the same mistake repeatedly until the phrase becomes easier.
Lingrow's listing describes this plainly: you can make mistakes without anyone judging you. Conversations also adapt to your level automatically.
Unlimited repetition
A tutor can repeat an activity, but each repetition uses paid lesson time. An app lets you rerun the same scenario as often as you need.
You might complete an ordering-coffee conversation, notice that quantities caused trouble and start again immediately. Tomorrow, you can repeat it before moving to the metro scenario.
The same approach works for higher-stakes situations. Run a job interview until your answers become steady, change to a work meeting, then return to the interview later.
Lingrow also saves words from your conversations into a flashcard deck. Spaced repetition and curated decks help you revisit vocabulary after the conversation, while progress stays separate for each language.
Instant feedback on every turn
A tutor must decide when to interrupt and when to let a conversation continue. Correcting everything can break the flow, while saving every note until the end can make feedback less precise.
Lingrow gives real-time corrections while you speak. After the conversation, it summarises grammar, vocabulary, fluency and pronunciation, with specific tips about what to fix next.
For example, you can complete a restaurant exchange and see that your request was understandable but needed a grammar change. You can apply that correction in the next turn instead of waiting for a future lesson.
This cycle is hard to match in booked sessions. Lingrow provides it through a subscription with a free trial, while italki Japanese tutoring costs around $15 to $60 an hour as of September 2026.
How to decide by goal
Travel
Start with the app. Practise ordering coffee, using the metro and asking for directions until the useful phrases come quickly. A tutor is unnecessary for most trips, though you can add one if you can afford it and want personal preparation.
Exams
Use Lingrow every day to build speaking volume for the JLPT, TOPIK, DELE, IELTS or a university oral examination. If your budget allows, add a tutor during the final weeks for timed mock tests and writing marked against the relevant criteria.
Work
Use the app for daily meeting and interview roleplays. Add a tutor when you need to polish an important presentation, choose a formal register or review an email where tone matters.
Family
Use Lingrow to practise speaking with in-laws, grandparents or a partner's parents. Daily conversation builds confidence before real visits and calls. Your family can then provide the cultural nuance that no general lesson can fully supply.
Fun
For a long-term hobby, the app is enough for regular conversation, guided lessons and vocabulary review. Add a tutor only if you enjoy the human contact and can comfortably afford it.
A routine that uses both
Practise in Lingrow for 20 minutes every day. Use voice scenarios on most days, then add guided lessons and flashcards when you need an explanation or vocabulary review.
If you can afford it, book one 30 to 60-minute tutor lesson each week. Bring a defined task, such as a mock speaking test, a cover letter or questions about formal register.
The app handles volume, while the tutor handles depth. In a typical 60-minute tutor lesson, the student speaks for about 15 to 25 minutes. With an app, nearly the whole practice session can be spent speaking.
A simple week might include four scenario sessions, two guided lessons and one review of saved words. The optional tutor lesson can focus on patterns found during those sessions rather than spending paid time warming up.
If you can choose only one, choose the app. Daily practice matters more than an occasional premium lesson, particularly when your main goal is comfortable conversation.
The bottom line
An app like Lingrow should be the base of your language routine. It gives you daily speaking, immediate corrections, guided lessons, repeatable scenarios and vocabulary review without bookings or social pressure.
A human tutor is an optional add-on for people who can afford one. Use that person for timed exam practice, long writing, accountability and cultural decisions where context matters.

Frequently asked questions
Do I need a tutor to learn a language?
No, most learners don't need a tutor for daily speaking practice. An app like Lingrow gives you guided lessons, voice conversations, corrections and vocabulary review whenever you have time. A tutor becomes useful when you need exam marking, detailed writing correction, accountability or a human judgement about cultural nuance.
Can an app replace a language tutor?
For regular conversation practice, Lingrow can replace much of what learners book tutors to do. You can speak through 350+ scenarios, receive feedback and repeat difficult situations without another booking. A human tutor is a useful optional add-on for formal exam coaching, long written work and sensitive questions about register or culture.
When should I hire a language tutor?
Consider hiring a tutor when you have a specific task that needs human judgement. That might be a timed mock exam, a marked university application, a polished presentation or advice about a sensitive work email. Keep using Lingrow between lessons so that paid tutor time focuses on questions you can't resolve through daily practice.
Is an AI language app enough to become conversational?
An AI language app can provide the speaking volume needed to become more conversational. Lingrow lets you practise at your level, receive corrections and repeat the same situation until your response feels automatic. You still need regular practice, and a tutor can add depth when a particular exam, document or cultural question demands it.
Should I use a tutor and an app together?
Yes, if a tutor fits your budget. A practical routine is 20 minutes of Lingrow conversation each day, plus an optional 30 to 60-minute tutor lesson each week. The app supplies frequent speaking and immediate feedback. The tutor can then concentrate on mock exams, long writing, formal register and difficult questions.
