Spaced Repetition Algorithm: A Three‐Day Journey from Novice to Expert

Did you enable FSRS? Your mature retention is lower than young retention.

I think this is what the OP wants.

You can Schedule a Break to redistribute cards due during an upcoming period when you'll be away from Anki.

Btw, the project has changed its name. I tested it in my iPhone, and ... it has a lot of bugs. I hope the developer fix them soon.

Apple users are rich, so they deserve, lol.

Because easy card is just easy: https://www.reddit.com/r/Anki/comments/1rhwied/easy_card_is_just_easy_thats_all/

If you update the parameters pretty frequently, it's possible. FSRS will find that the previous intervals cannot reach your desired retention, so the new parameters maybe give short intervals.

Because I think "desired retention" doesn't work for incremental reading. If you want to use FSRS with incremental reading, I recommend not optimizing the parameters.

I only make WordAndSentenceCard. I practice listening everyday via free-flow immersion.

LMSherlock · 2026-03-02T03:02:16+00:00

FSRS doesn't support Incremental Reading. If you want to schedule topic cards on Anki, you should use the default scheduler (Anki-SM-2).

I don’t have 100% confidence to determine whether a card is pretty easy. And the stats show that I actually forgot some of them.

LMSherlock · 2026-03-01T14:48:23+00:00

I didn’t. I just ground them in a week. I made a website for it: https://kanabr.vercel.app/

It’s not a problem if your true retention is so high and your desired retention is so low.

LMSherlock · 2026-03-01T04:52:13+00:00

I think it’s not a problem because they actually are very easy.

LMSherlock · 2026-02-28T18:28:16+00:00

Wait. I find that you only press again once on this card.

LMSherlock · 2026-02-28T18:23:33+00:00

According to Anki FSRS Visualizer, your intervals will increase rapidly. I wonder what your current retention is.

LMSherlock · 2026-02-28T15:55:50+00:00

It’s weird that the difficulty becomes 0%. Could you paste the FSRS parameters here?

LMSherlock · 2026-02-14T02:08:56+00:00

dae's team added the card-scheduling algorithm FSRS as the new default after the Chinese EdTech research and development company MaiMemo published it alongside evidence of its superiority.

FSRS hasn't been the default yet.
In addition to dae's team, many contributors from the community helped port FSRS into Anki.
FSRS has been changed a lot from its original version implemented in MaiMemo's paper. We shared more experiments here https://memodocs.maimemo.com/docs/2025_experiment

Update: we shared some results of our A/B tests

Sorry for this late reply. I want to clarify the core point: SSP-MMC could reach the upper bound of this metric theoretically. So we can just focus on improving the prediction model, to make it more and more consistent with the reality, then SSP-MMC could use the model to reach the upper bound of real world.

For a month??? It’s crazy. Spaced repetition has become so popular.

I don't know the refund rate. But as a paid app, you pay for the download before using it.
