A little help
with your reading.

The custom voices are bundled recordings. Natural uses a complete recording when available; otherwise it reads the sentence with the Japanese device voice. Word by word uses recorded words where available, with device speech for missing words. Some voices borrow the Clear recording.

The message beside the playback controls explains coverage. Selecting a voice does not generate a new recording of arbitrary text.

Starting with version 1.1.2, Word by word is the default unless you have already chosen another mode. It uses one recorded voice across the passage, choosing Clear when it covers more words than your selected voice. Missing words still use device speech.

In version 1.1.2 or later, choose Save in Read, then find it in Phrases > Saved. Saved phrases stay on this iPhone and can be searched, reopened or removed. The collection holds up to 500 phrases, with up to 2,000 characters each; longer readings must be shortened before saving.

Read a line from a built-in conversation to keep its Back to conversation link. Saving that line also keeps its source. Expressions work the same way. Pasted text has no assumed source, and editing a reading removes its old source link.

The dictionary, text analysis, kana exercises, saved study data and bundled recordings work offline. Device speech depends on the voices installed on your iPhone. Apple’s optional translation feature, language downloads, support and source links may require a connection.

Choose Translate beside the reading controls on iOS 17.4 or later. This opens Apple’s system translation interface. Apple manages language availability, downloads and translation processing. Depending on your language downloads and settings, text may be processed on the device or sent to Apple. See Apple’s Translation & Privacy notice.

Exercises use only the sounds you selected. Voiced kana, combinations, small tsu and long-vowel marks need their own selections. Add more sounds to unlock more built-in lines. Hiragana and katakana remember separate choices.

The katakana-only sentence display is a reading drill. Reveal the answer to see normal Japanese spelling and meaning.

In the 1.1 learning update, open Learn > Kana games to read, listen or distinguish similar shapes. Games use your selected kana, and the first answer counts. Hints mark an answer as assisted; unfinished rounds resume locally.

Learn > Story practice opens a short café scene with two roles and two choices. Tap a word to inspect it, listen to the model, then repeat aloud. The optional timer follows the recording’s duration. It does not record or judge your pronunciation. Earlier lines and either ending can be replayed.

Clear in Read removes the restored reading draft. Saved phrases remain in Phrases > Saved until you choose Remove; Undo is available immediately afterward. Open a saved word or kanji and turn off its bookmark to remove it from your collection; saved words also have a removal action in their context menu.

Deleting the app removes its local app data, including game and story progress. Ending a round or restarting a scene resets that attempt; completed progress stays saved. Offloading the app preserves data. Copies in device backups are managed separately through your Apple or computer backup settings.

No. Naninani currently keeps study data on the device and has no sign-in or account sync. The Yomu website is a separate product with optional accounts. A website account does not back up the native app’s saved words or kanji.

Select Japanese text and use the app’s Share action, then choose Read in Naninani. The extension needs text; sharing only a webpage address may not include the passage. If the text does not arrive, copy it and use Paste in Naninani.

Names, titles and ambiguous words can have more than one reading. Send the short passage, the reading you expected, and where the result went wrong. You can edit or remove private details before sending it. The app does not send the passage automatically.
