Need help with Korio? Most questions are answered below — and for anything else, we read and answer every email.

• Where do I start? The Alphabet tab. Nine short lessons, about twenty-four minutes, and after them Korean stops being shapes. Everything else assumes you can read them.
• Which words does it teach, and who decided? 10,635 words graded across TOPIK levels 1 to 6 by 국립국어원, Korea’s National Institute of Korean Language. The order is theirs, not ours. Settings → Where the content comes from has the full attribution.
• What is in the app, and what is Pro? TOPIK I — levels 1 and 2, 1,835 words with audio, offline — is open from the start, plus two pronunciation rules and a working grammar preview. Pro opens levels 3 to 6, the rest of the rules, all of grammar, and removes the daily practice limit.
• Why does a word show no pronunciation? Because the rules cannot settle it. A few sound changes depend on whether a word is Sino-Korean or on where a compound joins, and rather than guess, Korio shows nothing. About 6% of entries are held back this way.
• Why is the 0.6× audio slower for words than for sentences? Words were re-spoken at that rate, so they are a real slow reading. Sentences have no slow recording and are the normal one slowed by the player, which sounds flatter. Settings says so too.
• Do I need to download anything? Levels 1 and 2 ship inside the app, audio included. Levels 3 to 6 are 58–98 MB each and download from Settings → Audio downloads when you reach them.
• The pronunciation practice will not hear me. It needs microphone and speech recognition permission, and Korean dictation available on the device — that follows your keyboard settings in iOS. The rest of the app works without it.
• How do I start over? Settings → Start over → Reset all data. It erases your progress, streak, downloads and reminder, and returns you to the introduction. Your subscription is not affected — Restore purchases brings it back.
• I subscribed but Pro is not showing. Open Settings in the app and tap Restore purchases. Pro is billed through your Apple Account and works on any device signed in to it.
