Keep your decks. Add the interrupt.

AnkiDroid is free, open source, and already does spaced repetition better than anything we could write. This page is about the one thing it does not do, and about being straight with you about the two free apps that already cover that ground.

The AnkiDroid connector, in short

If you already keep AnkiDroid decks, keep them. Popcue reads them, keeps AnkiDroid’s own SM-2 scheduling, and becomes purely the interrupt layer: the thing that puts a card in front of you when you open a distracting app. Free and uncapped on every tier, Pro included, because the deck is yours and we are not generating it.

AnkiDroid itself is free, open source, Android, with 10M+ downloads, about 165K reviews and a 4.7 rating on Google Play. It uses SM-2. It does not block apps. That last fact is the entire gap this connector fills, and its Play Store listing is where we checked it on 30 September 2026.

There is also AnkiBlock, a free open-source Android app with 500+ downloads that blocks apps until your AnkiDroid daily card goal is met, and offers a 60-second temporary unlock up to three times a day. Both of those apps are free, and if one of them solves your problem, use that one. Popcue is not yet on the Play Store.

The honest version first

Most pages in this category are written to make the product sound inevitable. We would rather start with the version where it might not be.

If you already run Anki every day, AnkiDroid alone is free and nothing here is a reason for you to pay for anything. It is free, it is open source, it has ten million downloads, and its SM-2 scheduling is the same algorithm Popcue uses. AnkiBlock is also free and also open source, and it already blocks your apps until your daily goal is met. If the daily goal is enough structure for you, you have two excellent free answers today and this page is a footnote.

What follows is the case for Popcue anyway, stated at its strongest without pretending the free options are bad. There are two arguments, and they are specific.

1. A per-launch ratio instead of a daily quota

AnkiBlock’s model is a daily card goal. Meet it and the apps are yours; miss it and they stay shut. That is a good model, and it is the right one for some people. Popcue’s is different in kind: the ratio is per launch, 5 out of 10 by default and randomized within that, and it is set per app.

Three practical differences:

  • The days you do zero reviews still interrupt. A daily quota is only enforced on days you meant to study. On a day you forgot, the quota is empty and nothing happens. A per-launch ratio does not care whether today was a study day.
  • It is per app, not global. You can set the feed at 10 in 10 and the group chat at zero, and the ratio means what it says for each one.
  • Randomized inside the ratio. Every fifth launch on a visible counter becomes something you brace for. Random does not, which is why the default is 5 rather than 10.

2. No bypass, and a different bypass anyway

AnkiBlock offers a 60-second temporary unlock, up to three times a day, which is a real escape hatch and a deliberate one. Popcue’s rule is different: there is no skip control on either step of the interrupt, and no setting that adds one. You tap to reveal the answer, then tap to rate it Got it or Still learning. Both taps are required.

Whether that is better is not for us to say, and it is not for us to hide either. Some people want the hatch. If you want a hatch, AnkiBlock has one and it is free. The reasoning behind Popcue’s rule is on the how-it-works page, including the version where we say it plainly is a design position rather than a research finding.

And the honest third argument, which is not a Popcue feature so much as the reason to be in this section at all: the AnkiDroid connector is one of three, alongside Notion and an MCP-compatible LLM endpoint you already run (Todoist is coming soon). All three are free and uncapped on every tier.

Read the downloads row and then read the rest of the table, because the downloads row says something we would rather say ourselves: AnkiDroid has ten million installs and 4.7 stars, and Popcue has no installs and no stars. We are asking you to judge a product with no public track record on the strength of two mechanical differences and a set of free connectors. The Anki and Mochi comparison page covers the same ground across more of the category, and the full comparison matrix has eleven capability claims including the ones where we say no.

How the AnkiDroid connector works

  1. Grant AnkiDroid access, an optional permission

    On Android, Popcue reads your AnkiDroid collection with a permission you grant from inside the app. It is requested only when you use this connector, and it is revocable from Settings, then Apps, then Popcue, then Permissions.

  2. Your decks stay where they are

    Nothing is imported into a Popcue library and nothing is moved. Your collection remains an AnkiDroid collection, syncing the way it already syncs, and AnkiDroid remains where you do your reviews.

  3. SM-2 stays AnkiDroid’s SM-2

    The connector does not re-schedule your cards on Popcue’s own timeline. AnkiDroid’s scheduling is preserved, because a deck you have maintained for a year has intervals that reflect two years of honest ratings, and throwing them away to start a new schedule would be a disservice.

  4. Popcue becomes only the interrupt

    Pick the apps you want wrapped, set the ratio, and when one of those apps comes to the foreground a card from your deck is on screen. Tap to reveal, tap to rate, and the app opens. That is the whole of Popcue’s contribution here: it is the door, and AnkiDroid is the room behind it.

What happens to your AnkiDroid material

This connector has the shortest privacy story of the connectors, because the material is already on the device that runs the interrupt. There is no third-party service doing the reading and no workspace to grant access to.

Where the material goes
Nowhere. Your decks are on your phone, Popcue reads them on your phone, and the cards are drawn on your phone. This is the only connector that does not involve another company’s servers at all.
What leaves your device
Nothing from your decks, to us or to anyone. Popcue stores the connection configuration, the card state the scheduler needs, and your ratings.
What happens to AnkiDroid’s scheduling
It is preserved, not replaced. AnkiDroid stays the place your collection lives and the place your reviews are done.
How to stop it
Revoke the permission from Android’s settings, or disconnect the connector inside Popcue. AnkiDroid is unaffected either way and keeps working exactly as it did.

If you only want AnkiDroid, install AnkiDroid. It is free, it is open source, and it is the better flashcards app of the pair. Popcue adds an interruption mechanism on top of decks you already have; it does not make your decks better, and it is not a replacement for a study habit you have already built.

Questions people ask about the AnkiDroid connector

Does Popcue replace AnkiDroid?

No, and it is not trying to. Keep AnkiDroid, keep your decks and keep AnkiDroid’s own SM-2 scheduling. Popcue reads those decks and adds the one thing AnkiDroid does not do: put a card in front of you when you open an app you chose to wrap. AnkiDroid remains the place you study; Popcue is only the interrupt in front of it.

Do I need Popcue at all if AnkiDroid is free?

Probably not, if you already open AnkiDroid every day and finish your reviews. AnkiDroid is free and open source and does not block apps, and AnkiBlock is also free and open source if you want a daily quota enforced for you. Nothing on this page is a reason for you to pay for anything. The reason to look at Popcue is the per-launch ratio instead of a daily quota, the no-bypass rule, and the other connectors.

Can I use Popcue with AnkiDroid on a computer or on iOS?

AnkiDroid is an Android app, so the AnkiDroid connector is the Android path. Popcue also runs on the web, where the other connectors work, and there is no iOS version of Popcue and none is scheduled.
