LingFit's Grammar Classes Reviewed: One Rule, One Practice Chapter
What a LingFit grammar class includes, how "Practice Now" works, how progress is shown, and where the limits are.
Pros
- One rule per class, in plain language with examples
- Each class has its own practice chapter ("Practice Now")
- Unfamiliar words in the explanation are tappable, with audio and translation
- Included in every language direction
Cons
- Does not replace a textbook with tables, exceptions, and background
- No teacher to correct free sentences
- Only up to level B2
The short answer: LingFit’s grammar classes each explain one rule briefly and with examples, then send you straight into a matching practice chapter. For learners who like grammar in small steps, that’s a useful tool. It doesn’t replace a textbook or a teacher.
What we looked at
- Explanation: How understandable and how extensive is a class?
- Practice: What happens after reading?
- Progress: Can you see what’s done?
- Limits: Where do you need extra help?
What a class includes
Each grammar class covers exactly one rule. The explanation is in plain language and includes example sentences. The base language is your own: if you’re learning Italian with German as your starting language, you read the explanation in German.
Every unfamiliar word in the explanation can be tapped. You hear the pronunciation, see the translation, and can add the word to your saved words. That’s handy because example sentences often contain vocabulary you don’t know yet.
Practice Now: the real value
At the end of each class is the “Practice Now” button. It opens a dedicated practice chapter tailored exactly to that rule. The exercises come from the same toolkit as the main course, such as fill-in-the-blank texts where you choose the correct verb form or ending, or sentence-building tasks where the word order has to be right.
That pairing is the most important point. Many grammar explanations in apps or online remain mere reading material. Here, reading is immediately followed by applying it while the rule is still fresh.
Progress
The status of each class is shown: current, completed, or not completed. That way you can see at a glance which rules you’ve already worked on. There’s no test in this form to check whether you still have the rule down weeks later; for that, you have to repeat the practice chapter yourself as needed.
How far does that get you?
For most everyday goals up to B2, the concept covers the typical questions: which tense when, which article, which preposition. But there are clear limits:
| Need | Grammar classes in LingFit | Also useful |
|---|---|---|
| Understand a rule | Yes, briefly with examples | – |
| Practice the rule right away | Yes, with its own chapter | – |
| Complete tables and exceptions | Only to a limited extent | Grammar book |
| Have free writing corrected | No | Teacher, course |
| Level C1/C2 | No | Advanced course |
Especially with languages that have many forms, such as Polish, Czech, or Hungarian, many learners will also want an overview in book form. That’s not a flaw in the app but a realistic expectation of short explanations.
How the classes fit into everyday learning
The grammar classes sit alongside the main course, not in a fixed sequence within it. That gives you freedom but also requires a decision about when to work on which class. A sensible approach:
- Stumble in the course. When a form comes up in the course that you don’t understand, such as an unfamiliar verb ending, note the topic.
- Read the matching class. Find the class for that rule and read the explanation with the examples.
- Practice right away. Start “Practice Now” while the rule is still fresh.
- Review. Do the practice chapter again after a few days to check whether the rule has stuck.
The progress display with “current,” “completed,” and “not completed” helps you not forget classes you’ve started.
The role of the base language
An advantage that’s easy to overlook: the explanations come in your base language. If you’re learning German with French as your native language, you read the rule in French and can more easily place differences from your own language. LingFit offers this for English, German, French, and Spanish as base languages. That’s especially valuable with grammar because technical terms in a foreign language can add confusion. You can also have words in the explanation explained via an AI button if the translation alone isn’t enough.
Price and value
The grammar classes cost nothing extra. They’re included in every language direction and in the subscription. According to the manufacturer, the annual subscription is about $40; in the US App Store we saw $44.99 per year on October 10, 2026. The 7-day trial of the annual subscription is enough to work through a few classes and see whether the explanation style suits you.
Who it’s for, and who should skip it
A good fit for: - Learners who have avoided grammar so far and prefer small steps - People who want to look up after a lesson in the course why something is the way it is - Learners who want explanations in their own language instead of English
Skip it if: - You want to learn grammar systematically and completely, as in a degree program - You need feedback on your own writing - You’re working toward an exam beyond B2
Quick questions about the grammar classes
Are the classes available in every language direction? Yes, according to the manufacturer, each of the 42 directions includes a grammar course.
Do I have to do the classes in a fixed order? The manufacturer doesn’t describe a fixed required order. You see the status of each class and can choose specifically.
Do the practice chapters cost credits? No. “Practice Now” is part of the class and included in the subscription; only your own packs require credits.
Alternatives
Babbel and Busuu also integrate grammar into their courses and are well-established options. A classic grammar book with an exercise section remains the most thorough solution for tables and exceptions. For feedback on free writing, there’s no way around a teacher, whether in an in-person course or online.
What we couldn’t check
The manufacturer doesn’t say how many grammar classes there are per language direction. Whether the selection of rules matches your curriculum or exam is something you should check yourself during the trial by comparing the list of classes with your coursebook.
Bottom line
The grammar classes are lean, understandable, and sensibly linked to exercises. They’re a good tool within an app course up to B2 but not a replacement for a textbook or lessons. Our assessment as publisher: 8.6 out of 10. The language directions in which the classes are available are listed on the LingFit website.
Bottom line
The grammar classes are a good tool for understanding a rule and applying it right away. As a supplement to the course, in our assessment they do exactly what they promise. If you need deep systematic coverage or correction of free writing, you'll also need a textbook or lessons.
