A review is a short quiz on something you already learned in a lesson. Fuguro brings each item back for review on a timer, and makes the gap a little longer every time you get it right. That timing system is called spaced repetition, or SRS. You don't set up or schedule anything, it all happens on its own.
When an item's timer runs out, it joins your review queue. Your dashboard shows how many are due, and tapping Reviewsstarts a session. You don't have to look for anything.
The card shows only the character or word, with no mnemonic or hint on screen. You type the answer yourself. Trying to remember it, even when it's hard, is what makes the memory stronger.
After you answer, the card shows the full answer: the meaning, the reading, the audio where there is some, and an example sentence. This happens whether you were right or wrong, so a wrong answer is a chance to study it again right away.
Get it right and the item waits longer before it comes back. Get it wrong and it comes back sooner. The exact timing is below in How the timing changes.
Each session gives you up to 75 reviews at a time (you can change this number in Settings). The rest wait in the queue. The dashboard's Future forecast shows how many reviews are coming over the next 12 hours, so you can pick a good time to sit down.
In Kana Awakening, a review shows one kana character and asks for its sound. That's the only thing it asks.
The card shows a character like か, and you type its sound: ka. Get it right and you go straight to the next card. Get it wrong and the correct reading and its mnemonic appear so you can go over it.
Each correct review pushes the next one further out. Kana start fast, then slow down:
In Core Ascent, each review has two parts. You answer what the word means, then how it's read.
First you type the English meaning. Then you type the reading: type it in romaji and it turns into hiragana as you go. You need both parts correct for the item to count as a pass. If you miss either one, the item counts as wrong, even if the other part was right.
Each correct review pushes the next one further out. Core words use slightly longer gaps:
Doing your reviews is also what unlocks new levels (see Lessons & Phases). On your dashboard, the SRS chart groups your items into five ranks, from Recruit up to Immortal. For what each rank means, read Ranks & Promotion.
Anything you get wrong in a session is saved to Revision so you can look at it again the same day. Revision is just a recap: it shows you the answer again but does not change the review timing. Do it while the mistake is still fresh.
All of Phase 1 is free, and Phase 2 is free through level 5, with real lessons and real reviews. After you reach level 6 of Core Ascent, new lessons need Fuguro Plus, but every review you've already unlocked keeps coming back for free on any plan. More in Billing & Plans.
