Free vs Premium in LangBlitz

LangBlitz is free to start, with no account and no payment required to begin learning. This guide breaks down exactly what the free tier includes, what premium adds on top of it, and a few practical things worth knowing about how the two interact, including what happens if a subscription lapses.

What Free Includes

Free users get full, permanent access to fifteen word cards, chosen to span a range of topics and difficulty levels so you get a genuine feel for what studying in LangBlitz is actually like before deciding whether to upgrade. These fifteen cards are not a time limited trial, they remain available for as long as you use the app, whether or not you ever subscribe to premium.

Alongside those fifteen cards, free users get the Word of the Day widget, a small home screen widget showing a new featured word and definition each day without needing to open the app at all, and full ability to browse all one hundred and nineteen topic groups to see what is available across the entire library, even though only the fifteen free words within reach are actually study ready without premium.

Daily Quiz is available to every user regardless of tier, free or premium, once per day.

What Premium Includes

Premium unlocks the complete word library, more than five thousand curated words across all one hundred and nineteen topic groups and every CEFR level from A1 to C2, with no card by card limit. Every word in that full library carries the same depth as the free fifteen: definitions, nuance notes, example sentences, synonyms and antonyms, collocations, etymology, mnemonics, and common mistakes.

Premium also unlocks unlimited Practice Quiz sessions, the adaptive quiz mode that specifically targets words and questions you have struggled with most, covered in detail in the Daily Quiz and Practice Quiz guide.

Vocabulary World, the interactive 3D globe visualization of your entire vocabulary colored by mastery level, is open to every user, but only premium lets you tap into every word on the globe, including ones you have not studied yet, rather than just your fifteen free words. It is covered in its own guide. The Fast-track Level Up test, which lets you attempt to skip ahead to the next CEFR level by passing a fifty question exam rather than waiting on automatic progression, also requires premium.

Finally, export and import, the backup and restore feature that lets you save your progress to a file and move it to a new device, is premium only. Given how much time a serious vocabulary learner invests over weeks and months, this is worth factoring in specifically if you expect to switch phones at some point while still actively using the app.

Subscription Plans

LangBlitz offers premium through monthly, annual, and lifetime purchase options, giving you flexibility depending on whether you want to try premium for a shorter commitment or pay once for permanent access. Refer to the app's premium upgrade screen to see the latest pricing.

A Quick Side by Side Summary

To make the comparison easy to scan, here is what each tier boils down to in practice. On the free tier: fifteen fully unlocked word cards forever, the Word of the Day widget every day, browsing access to all one hundred nineteen topic groups, and Daily Quiz every day. On premium: everything free includes, plus the complete library of over five thousand words with no per card limit, unlimited Practice Quiz sessions, full access to every word in Vocabulary World, the Fast-track Level Up test, and export and import backup.

How Upgrading Works

Throughout the app, premium only features are marked with a small lock icon, for example next to Practice Quiz and Fast-track Level Up on the home screen. Tapping a locked feature takes you to the upgrade screen, where you can review the available plans and subscribe.

There are actually several separate doors into that same upgrade screen, not just one. Tapping any locked word inside Vocabulary World gets you there. Tapping the Practice Quiz or Fast-track Level Up tiles on the home screen while on the free tier gets you there. Trying to export or import your progress while free also offers a path in. And you do not need to stumble into a locked feature at all to reach it: Settings has a dedicated Upgrade to Premium row sitting directly beneath your subscription status, visible only while you are on the free tier, that takes you straight to the same upgrade screen on demand. Once you subscribe, that row disappears from Settings entirely, since there is nothing left to upgrade to.

Wherever you land on the upgrade screen from, the screen itself is identical: the same monthly, annual, and lifetime plans, the same pricing, and the same subscription flow through Google Play. The only thing that differs between entry points is which specific feature nudged you there in the first place, which mostly matters for the app's own understanding of what motivated the tap, not for anything you see or choose on the screen itself.

Restoring Purchases on a New Device

Your premium subscription is tied to your Google Play account rather than to any file or local device setting, which is different from how your actual review progress works, covered in the export and import guide. If you get a new phone and install LangBlitz fresh, your subscription does not automatically appear the moment you open the app. Instead, go to Settings and use the Restore Purchases option, which checks your Play account for an active subscription and reactivates premium access accordingly, assuming you are signed into the same Google account you originally subscribed with.

What Happens If Your Subscription Lapses

If a subscription ends, whether through cancellation or a payment issue, nothing about your actual study history is deleted. Every word you have reviewed, your streak, your stability and difficulty data behind the scenes, all of it stays exactly as it was, saved locally on your device the same way it always has been.

What changes is access going forward. You return to free tier limits, meaning new word introduction is restricted back to the fifteen free words, Practice Quiz becomes unavailable again, and Vocabulary World goes back to only showing full detail for your fifteen free words rather than every word on the globe. Importantly, none of your premium era progress is deleted, it is simply set aside. Words you introduced and studied during your time as a premium subscriber remain saved in your review history exactly as they were, but they stop coming up for review while you are back on the free tier, since review sessions on the free tier pull only from your fifteen free words, the same as new word introduction. Those other words are not lost, they are effectively paused, and the moment premium is active again, they pick back up on their normal spaced repetition schedule right where they left off. Daily Quiz and Practice Quiz specifically stay correctly scoped to only your free tier accessible words once you are back on the free tier, rather than continuing to draw on your full premium era history.

What Happens When You Resubscribe

Reactivating premium, whether by subscribing again directly or by using Restore Purchases after signing back into the same Google account, immediately reverses the pause described above. Every word you introduced during your earlier premium period is still sitting exactly where you left it in your review history, and as soon as premium is active again, those words rejoin your regular review sessions on their normal spaced repetition schedule. Nothing needs to be re-imported or manually restored for this to happen, since the underlying data was never removed, only excluded from free tier sessions while premium was inactive.

One practical detail worth knowing: a word that was due for review during the time you were on the free tier does not simply vanish from the queue, it will typically show up promptly once premium resumes and reviews open back up for it, rather than waiting for its original scheduled date to arrive again. This can make your very first session back on premium feel a little heavier than usual if you were on the free tier for an extended stretch, since a backlog of previously introduced words may all become eligible for review at once. That is expected, not a sign anything went wrong, and it settles back into a normal rhythm within a session or two.

Deciding Whether Premium Is Worth It

Whether premium makes sense depends heavily on how you intend to use the app. If your goal is casual, ongoing vocabulary exposure without a specific deadline, the free tier's fifteen words plus the Word of the Day widget might genuinely be enough for a long time, giving you a new word to pick up each day with zero pressure to open the app at all. If you are preparing for a specific exam like IELTS, TOEFL, or GRE, covered in more detail in the exam prep guide, the full word library becomes much more relevant, since serious exam vocabulary coverage requires far more than fifteen words regardless of how well chosen they are. If you know you will be switching devices during your study period, the backup feature alone is worth strong consideration, since losing weeks or months of accumulated spaced repetition history to a phone upgrade is the kind of loss that is genuinely hard to recreate quickly.
