Among language learning apps free to download, Duolingo suits a daily habit and Drops suits vocabulary building. Neither alone reaches fluency, so pair an app with real speaking practice once the basics feel comfortable.
Apps handle repetition well and conversation poorly. If slang and informal speech are your goal, read how to learn slang in a new language alongside this guide.
Why free apps help and where they stop
Free language apps work because they turn repetition into a routine, and they stop working when you need someone to react to what you say. Two mechanisms explain most of their value.
- Gamification builds the habit. Duolingo says it pairs playful rewards and achievements with making practice a daily routine. That suits learners who struggle to start, because the reward arrives within a short session.
- Spaced repetition builds vocabulary. Drops describes spaced repetition, contextual learning and visual association as its method, and says its content covers over 5,000 words and phrases. That makes it a vocabulary tool first and a grammar course second.
The limit follows from the design. A lesson that checks a tapped answer or a repeated phrase cannot judge whether a listener would understand you. Treat the app as the practice layer and add a conversation layer yourself, as the later sections describe.
Free apps compared: Duolingo and Drops
The table sets the two apps side by side on the points that matter before you commit time: languages, the main strength, and what the paid tier reveals about the free one.
| App | Languages | Main strength | What the paid tier adds | Planning use |
|---|---|---|---|---|
| Duolingo | 40+ languages, including Spanish, French, German, Italian, Russian, Portuguese, Turkish and Dutch | Short lessons covering speaking, reading, listening and writing, with rewards for daily practice | Super Duolingo removes ads and adds perks such as Unlimited Energy and Monthly Streak Repair | Start here if you need a low-friction daily habit and your language is on the list |
| Drops | 55+ languages | Vocabulary with over 5,000 words and phrases, plus pronunciation and listening work | Premium adds unlimited learning time, all game modes, ad-free use and offline learning | Choose it for word learning, or when your language is missing from Duolingo |
Figures come from the Duolingo App Store listing and the Drops website; the language counts describe each app’s own catalogue.
Duolingo: habit first, depth later
Duolingo states that every course is free, and it describes lessons as quick and bite-sized. That suits beginners who want exposure and a streak to protect. The paid tier lists Unlimited Energy as a perk, so expect the free version to meter how much you can practise in a sitting. Plan around that by using the app for a warm-up and moving on to other material when the meter runs out.
Move beyond Duolingo as the main tool once the lessons feel repetitive and you want to hold a real exchange. At that point the app still earns a place as daily review, but it should no longer carry the whole plan.
Drops: focused vocabulary and wider language coverage
Drops advertises free learning for 55+ languages, which is a larger catalogue than Duolingo’s 40+. It also says it builds pronunciation and listening so learners feel confident communicating. Its Premium tier lists unlimited learning time, so a free session is likely to be time-limited; use short, regular sessions rather than long ones.
Drops also says learners progress 2x faster on average with Premium. That is a vendor claim, not independent research, so test the free version before paying and pay only if time limits become the specific barrier.
Matching an app to your goal
Choose by the skill you most need next, not by popularity. Work through these stages in order.
- Write the goal as a task. A line such as “describe my job aloud” tells you more than “get better at Spanish”. The task shows which skills to train: words, listening, pronunciation or speaking.
- Match the skill to the mechanism. For words, pick a spaced-repetition tool such as Drops. For routine and balanced skills, pick Duolingo. For speaking with feedback, plan on a human partner, because neither listing describes a live conversation partner.
- Check the language list first. Confirm your target language appears in the app’s catalogue before building habits around it. Duolingo’s listing names Spanish, French, German, Italian, Russian, Portuguese, Turkish and Dutch, while Drops states a larger overall count.
- Trial two candidates side by side. Use both for a short, fixed period and keep the one you open without being reminded. Switch if your progress stalls.
Your language choice also shapes how far an app alone takes you. Learners of Spanish can read How Long Does It Take To Learn Spanish?

Building a daily routine around free apps
A routine works when each session has a clear job and ends before it becomes a chore. Because free tiers can limit how long you can practise, short sessions fit the product as well as the learner.
- Start with the gamified app. Use Duolingo as a warm-up so the streak and rewards get you started. Duolingo describes practising speaking, reading, listening and writing to build vocabulary and grammar, so the warm-up already touches several skills.
- Follow with vocabulary review. Use Drops or a spaced-repetition deck for words that keep slipping. Review weak items more often than new ones.
- Add an active skill every session. Say new phrases aloud, shadow a short audio clip, or record yourself and compare it with a native speaker. The apps cover pronunciation and listening to some degree, but speaking out loud is the step they cannot check for you.
- Review mistakes weekly. Keep a short log of errors and revisit it. A log shows whether the same gap keeps returning, which tells you what to add next.
Measure progress with simple counts you can see: words added, lessons completed, and minutes spent speaking. If one count lags, shift your time toward it rather than adding another app.
Working around free-tier limits
Free tiers cost you time, attention and feedback rather than money. Ads, usage caps and locked modes are the usual price. Both vendors show this in what their paid plans remove: Duolingo’s Super tier removes ads and adds Unlimited Energy and Monthly Streak Repair, while Drops Premium lists ad-free use, unlimited learning time, all game modes and offline learning.
Fluency needs more than an app
An app can give you a solid base in words, listening and pronunciation, but fluency means producing language with people who respond. Drops frames its pronunciation and listening practice as building confidence in communicating, and Duolingo frames its lessons as practice. Confidence is a step toward fluency, not the end of it. The workable route is to use the app for repetition and switch most of your remaining effort to live conversation.
Practical workarounds
- Fill the feedback gap. Find a language partner or a community group for conversation, and record yourself to compare against native audio.
- Add input the apps do not provide. Podcasts, public radio and news sites in the target language give varied listening and reading, and they are where informal phrasing appears.
- Use a notebook as your own sentence bank. Copy useful phrases from lessons with a sample sentence of your own, then say them aloud.
- Pay only for a named barrier. If ads or time caps are what stop you practising, a paid tier may be justified; if the barrier is speaking, a subscription will not fix it.
Set concrete checkpoints, such as describing your job aloud or following a short podcast clip, and judge your apps against them. If an app no longer moves you toward a checkpoint, change the plan rather than the subscription.
Frequently asked questions
Is Duolingo really free?
Duolingo states on its App Store listing that every course is free. The paid Super Duolingo tier is optional and removes ads while adding perks such as Unlimited Energy and Monthly Streak Repair.
Is paying for Drops Premium worth it?
Only if time limits are what is holding you back. Premium lists unlimited learning time, all game modes, ad-free use and offline learning. The claim that learners progress 2x faster comes from Drops itself, so try the free version first.
Which free app suits a complete beginner?
Duolingo is the easier starting point for most beginners because its short lessons and rewards support a daily habit. Add Drops when you want to concentrate on vocabulary or your language is not offered by Duolingo.
Can I use both apps together?
Yes. Use Duolingo for a daily warm-up and Drops for focused word review, then spend your remaining study time on speaking and listening away from both apps.
