Recall — Write From Memory
Blind recall: the character is hidden and you write it from memory, with no tracing guide. Pick any row from the menu, write each kana, then a quick reading test locks it in. Your progress is shared with the rest of the site, so rows you've already learned show up as done.

Katakana Recall — Write Every Kana From Memory
Recall is blind writing practice for Katakana: the kana is hidden and you write it from memory, one row at a time. Finish a row and a short reading test confirms you can recognise it too, while spaced repetition brings each character back for review right before you would forget it.
How recall works
Choose a row and each character appears as a prompt with the glyph hidden. Draw it from memory; if your strokes match, it counts. Clear the whole row and you move to a quick reading round, then a free-writing round. Every attempt updates that character's writing and reading scores, so the site always knows what to show you next.
Why write from memory
Tracing teaches your hand the shape, but recall is what proves you know it. By hiding the character and asking you to produce it, recall surfaces the kana you only think you have learned and turns them into ones you can write without help.
Where to go next
New to a row? Learn the strokes on the chart first. To keep just your due characters sharp, review runs a shorter session. Once your kana are solid, kanji and grammar are the next step.
