More Cards Due on Desktop anki vs. Ankidroid

Anki Help
1

2 things:

This happens more often than I'm comfortable with, but my desktop anki shows more cards due than my ankidroid, until I sync - then they become equal (with ankidroid being updated with more cards due, to my annoyance). It's not giving me any confidence in the ability of anki/fsrs to do its job in scheduling my cards correctly.

I don't know if this is related to the above issue, but cards that I got correct the previous day that aren't relearn cards (hit 'good'), will come back the following day. I should see it in at mimimum 2 days, not the following day.

I didn’t take a screenshot for today (already synced), but I had 22 cards due in ankidroid, and 30 cards due on desktop anki. A difference of 8 cards.

*I also found that the number of review (not relearn) cards I hit ‘good’ on yesterday that are due today (even though it should be seen in at minimum 2 days), is also 8. I provided screenshots below:

(note: Highlighted cards are the ones I just completed yesterday, hitting ‘good’ that are back again today. Exactly 8 cards)

(Example card: Interval is supposed to be 2 days, but its due again today. FYI: my next day starts 4 hours past midnight.)

**I have doubled checked that the settings for fsrs and preferences are equivalent on both devices.

Can someone please provide an explanation? Is it simply because sometimes I don’t sync between devices before anki ‘resets’ for the next day? If that’s the case, that seems so unreliable, considering that aren’t both devices/apps supposed to pull from ankiweb? And shouldn’t it be updated from the most completed ‘version’ - meaning the device that you completed the most cards on for that day, if that makes sense?

Thank you to anyone who can help. Been dealing with this for a while now.

  1. Do you sync when you open the app AND when you close/leave the app, on every device, every time? If you have changes on more than one device at the same time, you may be leaving some cards in an inconsistent state. [Syncing before/after your next-day-starts time doesn’t matter, because both devices are using the same setting for that.]

  2. Do you have add-ons on desktop that run certain actions “on sync”?

  3. What versions of Anki are you using on each device? [Paste the entire result: For desktop – Help > About > Copy Debug Info. For AnkiDroid – Settings > About > Copy debug info.]

  4. How often are you reoptimizing your parameters/rescheduling your cards? Which device are you doing that on?

  1. Why do you think they should be set at a minimum of 2 days after graduating? That’s not something you can control directly with FSRS.

  2. When you reply, include your FSRS parameters [as text please, not a screenshot] and your Desired Retention.

    • I don’t do it on every device, but on the device I was currently using to complete the cards, I sync before and after. Also, I think it anki automatically syncs for me, but I sync multiple times before after.
    • If it is the case that I must go to my other device(s) to sync/update progress when I finish or sync on the device I was currently using – that seems extremely inconvenient. I don’t think I’ve ever had to do that before.
  • Do you have add-ons on desktop that run certain actions “on sync”?
    • I’m honestly not sure which add-ons run actions on sync. Below if a screenshot if that helps.

    • I reoptimize on my desktop mainly, rarely on ankidroid, which I thought wasn’t an issue since should both sync – the parameters and everything are the same on both.

    • I meant that hitting good for cards that aren’t relearning should be at least 2 days, not 1 day interval. For example, the screenshot above, I should see the card in 2 days, not the very day. Let me know if I need to clarify.

  1. :white_check_mark: Yes, what I meant was when you open on a device and when you close on a device you need to sync that device. You don’t need to sync on your other device until you open the app on the device.

  1. That could be the issue, so you might want to figure it out. [If you want to work on that, start by disabling any add-ons if you don’t know what they do, or you’re not actively using them. Then for the rest, start reading about what their sync actions are.]

    2.b. You’ve got a mess of add-ons, and I can’t tell you what they are all doing. But at least let’s look at one that definitely can impact scheduling – FSRS Helper. Are you using any of its “on sync” actions?

  1. :white_check_mark:.

  2. :white_check_mark:.

  1. Yep, you’ll need to clarify. You still haven’t said why you think those cards should always be set for 2d, no matter what.

  2. :white_check_mark:.

We’ve eliminated a lot of the possible causes – but both of these issues still sound like they are being caused by a reschedule.

Looking at that Card Info you posted – the most recent revlog corresponds to study on 3 April (because it was between midnight-4am before the next day starts), and the card was set for a 2d interval, so it would be due on 5 April. But when you looked at it today, it had a 1d interval instead, so it was due on 4 April. The way that happens is that something reschedules the card outside of a study session – and once it is rescheduled, your number of Due cards might not match between your devices until that new scheduling is synced to the other device.
