A to-do list tells you what to do. A card tells you whether you kept it.

The same task, read twice. Todoist already knows the procedure you run every week, the checklist you go through every Monday, the thing you always forget the third step of. The plan is for Popcue to read that material and ask it back as a question. That connector is coming soon: you cannot connect Todoist in the app yet.

The Todoist connector, in short: coming soon

Todoist is coming soon to Popcue and cannot be connected yet. The Popcue app lists it as “Coming soon”, and there is nothing to connect today. The plan is to turn your Todoist tasks into cards you are actively quizzed on, instead of a list you glance at and close: connect Todoist once, select the projects you want, and the tasks in them become recall material. When you open an app you have chosen to wrap, one of those tasks would come back as a question with a required answer. For cards from your own tools today, use Notion, AnkiDroid or your own LLM endpoint, or join the waitlist to hear what ships.

The reason it works is that a to-do list and a flashcard answer different questions. A list answers what do I do next. A flashcard answers do I still know this. Popcue reads the same task and asks the second question about it. The connector is planned to be free and uncapped on every tier, Pro included, as the other connectors are, because Todoist would be doing the reading.

No competitor we checked connects a to-do app, and Popcue does not yet either. The first half is a statement about the six blockers and note apps we compared, on 30 September 2026, not a claim about every product that exists anywhere. Popcue runs on Android and web, and is not yet on the Play Store.

A list and a card answer different questions

This is the whole argument, and it is smaller than it sounds. You already use Todoist. It is full of things that matter enough to write down, which is a high bar. Writing a task down is itself an act of intention, and the fact that a procedure made the list means you intend to keep doing it.

But a task manager is a machine for not forgetting to act, and it is not a machine for remembering without looking. Completion is the terminal state. Tick the box and Todoist’s job is done. What Todoist cannot do is ask you, three weeks later and with no warning, what the third step was. That is the question a cloze card asks, and it is the question a task manager has no way to ask.

The same task, read two ways. Both columns describe the material in your Todoist account; only the question changes.
  Todoist alone The same task as a Popcue card
What it asks you What have I not done yet? Do I still know how to do it without looking?
When it appears When you open the app When you open an app you chose to wrap, at the ratio you set
Can you skip it Yes, it is a list No. Reveal, then rate. Two required taps.
Terminal state The task is ticked The card is scheduled: sooner if you missed it, later if you got it
What it never notices That you have forgotten it Nothing is noticed by Todoist; the interrupt is what surfaces it

Here is the defensible version of the claim, stated honestly, and it is about the plan, not a shipped feature. Of the competitors we compared (One Sec, Opal, ScreenZen, Freedom, Study Lock and the Anki-adjacent apps) no competitor we checked connects a to-do app. Their card sources are built-in generations, PDF and text uploads, or your own notes. We did not audit every application store listing on earth, so we are not going to tell you that nobody has ever built this. We are telling you that among the apps we checked, on 30 September 2026, this was not there.

How the Todoist connector is planned to work

This is the design, not something you can do in the app today. It is written down so you can judge whether it is worth waiting for.

  1. Connect Todoist with OAuth

    You approve access on Todoist’s screen and Popcue receives a token, never your password. You can revoke it from Todoist’s own settings, and revoking there stops the reading immediately.

  2. Select the projects

    You choose which projects become card sources. A work project, a study list, a personal system, whatever is worth being tested on. Projects you do not select are never read.

  3. Tasks become cards across eight card types

    A recurring procedure suits a cloze, with one term blanked out of the sentence. A definition suits a plain question. A checklist suits a list card, answered by naming the items. A rule you hold confidently is better tested by being asked to reject it, which is a true-or-false card.

  4. The interrupt asks, and the card is labelled Todoist

    Every card shows that it came from Todoist, and which project it came from. You pick the apps Popcue wraps; when one opens, a card is on screen. Tap to reveal, tap to rate Got it or Still learning, and the app opens. Nothing is ever ticked off in Todoist.

A worked example: one recurring task, one cloze card

The following is an illustration with invented content, built to show the shape of the planned transformation rather than to describe anyone’s real setup, and the connector does not exist in the app yet. It is a recurring Todoist task in a study project, which is the kind of task this connector is for.

The task, in Todoist

A recurring task, every Monday, in a project called Placement. Its title is Send Priya the placement feedback before the Monday lab meeting, with a note that says the feedback goes in the shared folder and needs the week’s sample numbers.

The card, in Popcue

A cloze card, one term blanked out: Send Priya the ______ feedback before the Monday lab meeting. The answer is placement. Nothing is secret in it, and that is the point: the content is ordinary, the retrieval is the exercise.

What the transformation actually did, and did not do:

  • It changed the question, not the source. The task text is still in Todoist, under your account, editable there. Popcue did not fork it into a private copy that now disagrees with the original.
  • It blanked the term you would otherwise skip past. You have sent this feedback a dozen times. That is exactly why the third word is the one worth being made to produce.
  • It turned a recurring task into something schedulable. Recurrence is a good proxy for “this needs to stay sharp”: the task comes back on a calendar, and the card comes back on SM-2.
  • It never touched your Todoist state. Answering the card does not complete the task, snooze it, or write a note back. The card is a question about the task, not an action on it.

And the reason this is worth doing at all is the one the scheduler supplies: a card you rate Still learning comes back soon, and one you rate Got it comes back later. A task manager has no version of that. How the rating feeds SM-2 is explained on the how-it-works page.

What is planned for your Todoist material

None of this applies until Todoist can be connected, and it is the design rather than a description of shipped behaviour. The material goes to whichever service does the reading. If you connect Todoist, the material would be read by Todoist. Popcue would ask Todoist’s API for the tasks in the projects you selected and work with what comes back. It would not copy your task manager into a silo, and it would never write back.

What leaves your device
Requests to Todoist’s API for the projects you selected, and the card text Popcue generates from the tasks those projects contain. It travels over Todoist’s own HTTPS API, under a token you granted and can revoke.
What does not leave your device
Your Todoist password, which Popcue never sees. Projects you did not select. Anything from apps you wrap, beyond the fact that one of them opened. And any write-back: Popcue never completes, snoozes, renames or edits a Todoist task.
What Popcue stores itself
The connection configuration, the card state the SM-2 scheduler needs, and your ratings. Not a mirrored copy of your task manager.
How to stop it
Revoke the integration from Todoist’s own settings, or disconnect it inside Popcue. Either way the reading stops at once and your tasks stay where they were.

Do not connect the projects you would rather not be asked about. Task lists are where private things end up: a colleague by name, a medical appointment, a salary. Select the projects you would be comfortable being quizzed on and leave the rest disconnected. Popcue can only ask you about what you point it at.

Questions people ask about the Todoist connector

Can I connect Todoist to Popcue today?

No. Todoist is coming soon. The Popcue app lists it as Coming soon and cannot connect it yet. Notion, AnkiDroid and your own MCP-compatible LLM endpoint are the connectors to use now, and you can join the waitlist to hear what ships.

Why connect a to-do app to a flashcard app?

Because the two answer different questions. A to-do list answers what to do next. A flashcard answers whether you still know it. Popcue reads the same task and asks it back as a recall question, so a procedure you run every week stays available in your head instead of only in your task manager.

Will the Todoist connector complete tasks for me?

No, and it is designed not to. Answering a card in Popcue would never check a task off in Todoist and never write to your Todoist account. Popcue would read the tasks you selected and ask you about them, so a task you have already ticked could still be asked as a cloze, which is the point: retention outlives completion.

Will I be able to connect Todoist and Notion at the same time?

That is the design, but not yet, because Todoist cannot be connected today. Each connected source becomes its own learning path with its own cards, the interrupt draws from all of them, and every card shows which service it came from, so a Todoist task and a Notion page would never be confused for one another.
