The easiest app to stick with isn’t necessarily the one that teaches what you need. A five-minute lesson can make daily practice painless, but if your goal is to talk with relatives, finishing another set of word-matching exercises may not move you closer to a comfortable conversation. The reverse is also true: paying for live speaking practice won’t help much if you still need a way to learn basic words between sessions.
Choose a language learning app by starting with the task you want to do in the language. Then look for a format that makes you practice that task often enough to improve. An app can be your main course, a tool for one weak skill, or simply the thing that keeps you studying on busy days. It doesn’t have to do everything.
Match the format to the job
These are the main formats worth comparing:
- Guided lesson apps take you through a sequence of short activities. They’re a good starting point if you want structure and don’t know what to study next. Babbel’s courses combine speaking, listening, writing, grammar, and review; Duolingo uses short lessons and offers free, skill-specific practice. Neither format removes the need to use the language outside the lesson.
- Audio-first courses ask you to listen and respond aloud. They suit someone who wants to use a commute or build the habit of producing sentences without reading a prompt. Pimsleur centers its courses on audio lessons and also offers reading and other activities. If writing is your main goal, an audio course shouldn’t be your only tool.
- Flashcard apps help you retain words and phrases you’ve already encountered. Anki schedules reviews based on what you remember, rather than taking you through a language course. That makes it useful alongside lessons, reading, or conversation—not a substitute for them.
- Tutor platforms provide sustained conversation with a person who can respond to what you mean, ask follow-up questions, and adapt the lesson. On Preply, for example, a paid trial lesson lets you discuss your goals before deciding whether to continue with a tutor. This format asks for more money and a fixed place in your schedule, but it can address a gap that solo practice leaves open.
Start with one main format, not a stack of subscriptions. A beginner who likes a clear path might use a guided course and add conversation practice later. Someone who can read Spanish but freezes when speaking may be better served by a tutor and an audio course than by restarting beginner lessons.
Judge speaking practice by what you actually say
A microphone icon tells you little about the quality of speaking practice. Apps may ask you to repeat a displayed phrase, answer a prompt without seeing the words, or carry on an open-ended exchange. Those activities demand different things from you.
Repetition is useful when you’re working on sounds and rhythm. For instance, Babbel’s speech recognition gives feedback when you repeat a word or phrase in a speaking exercise. But repeating a sentence accurately isn’t the same as deciding what to say to a person. If conversation is your goal, try a prompt that makes you choose your own words. See whether the tool responds to your answer or merely checks it against an expected phrase.
Automated feedback and human feedback also solve different problems. A pronunciation tool can give you immediate chances to retry; a tutor can notice that your sentence is technically understandable but awkward for the situation. Busuu illustrates why plan details matter here: its free tier includes community feedback, while AI conversations and pronunciation feedback sit in Premium Plus and have language, level, or device limits. “Speaking practice included” is not enough information to make a buying decision.
During a trial, speak aloud for a few minutes rather than tapping through the lesson silently. Ask yourself: Did I have to retrieve words from memory? Could I express an idea I hadn’t rehearsed? Did the feedback tell me what to change? If the answer is no, the app may still be useful—but don’t buy it as your main conversation tool.
Look for review that makes you remember
New material feels familiar while it’s on the screen. The harder test comes days later, when you need a word without a multiple-choice hint. Spaced repetition addresses that problem by bringing material back for review at increasing intervals as you remember it.
When you compare review features, check what happens after you miss an answer. Does the app bring it back? Can you review material from older lessons, or only replay the latest unit? Most important, must you recall an answer before seeing it? Recognizing a word among four choices is easier than producing it in a sentence.
Flashcards can be excellent for travel phrases, course vocabulary, or words you keep meeting in books. Make cards from material you care about: a useful sentence or a word in context is often easier to use later than a bare translation. Keep the workload manageable, too. If making and reviewing cards starts taking time away from listening, reading, or speaking, the support tool has become the whole study plan.
Check whether grammar is taught or left for you to infer
Some learners are happy to notice patterns through examples. Others need a plain explanation of why a verb changed or where a word belongs in a sentence. Neither preference is a flaw; it affects which lessons you’ll finish and understand.
Don’t judge grammar instruction by a feature list. Open a lesson near your level and find a point you don’t already know. Does the app explain the rule, show it in several useful sentences, and then ask you to apply it? Or does it mark an answer wrong and move on? A short explanation at the moment you need it can be worth more than a large library of rules you never open.
Check the exact language and level you plan to study. Babbel’s separate Grammar Guide, for example, is designed for beginner levels in selected languages; that is more specific than saying the app “has grammar.” If you need a syllabus, assignments, or feedback on extended writing, you may want a formal course rather than an app alone. The same questions you’d use to evaluate an online course’s structure and outcomes can help you decide when a course is worth the extra commitment.
Make sure offline access covers the lessons you need
“Works offline” may mean downloaded audio, saved vocabulary, full lessons, or only a small part of an app. It matters if you study on a subway, travel without reliable service, or want to avoid using cellular data. Test it instead of relying on the label: download a lesson, switch your phone to airplane mode, and try every activity you expect to use.
For example, Babbel lets you download full lessons and podcasts and review saved vocabulary offline. That doesn’t mean every online feature works without a connection; its help page advises a stable connection for speech recognition. Also check whether your progress syncs when you reconnect. A feature that works perfectly at home but not during your actual study window is the wrong feature to pay for.
Compare the cost of a usable routine, not a headline rate
The relevant price is what it costs to do the practice you need for the next few months. A free course may cover your lessons but not the kind of speaking feedback you want. A low advertised monthly rate may require paying for a year in advance.
The pricing models differ substantially. Duolingo offers course content for free and charges for additional subscription features. Babbel’s subscription terms say that longer plans are paid in full upfront and that prices can vary by purchase channel. Anki’s computer version and AnkiDroid are free, while the official AnkiMobile iPhone app costs $24.99 as a one-time purchase. A tutor is a different commitment: Preply’s subscriptions are tied to one tutor, with a minimum of four lessons per 28-day cycle and a total that depends on the tutor’s rate.
Before paying, check what your chosen language and device actually unlock. Compare the total charge at checkout, not just a per-month equivalent. Note when a trial converts to a paid plan, whether the subscription renews, and how to cancel it. If you’re unsure you’ll use the app, a shorter commitment is usually a better test than buying the cheapest annual rate.
Run a one-week test before you commit
Pick a realistic goal for the week: hold a two-minute introduction, understand a short exchange, or remember 20 words from material you’re studying. Try no more than two main tools. Use each in the time slot you’d normally have—ten minutes after breakfast, perhaps, or half an hour on the train.
At the end of the week, ignore the streak and test the skill. Can you say something without a prompt? Recall words away from the screen? Explain a grammar choice? Just as important, did you want to open the app again? A demanding program you avoid is a worse fit than a simpler one you use and supplement thoughtfully.
Keep the tool that earns a regular place in your week. Add another only when you can name the gap it will fill. That’s a stronger way to choose than trying to find one app that claims to teach everything.
