## What is Kio Flow?

Type by talking — in any app
Install the Kio Flow keyboard, tap the mic, and start talking. Words appear as you speak, and what you get is clean, properly punctuated text you can send right away. No app switching, no copy and paste.

Text that tidies itself up
Real speech has filler words, repeats and missing punctuation. Kio Flow turns it into sentences that read well, and changes the tone in one tap — more formal, shorter, whatever you need.

More than 20 languages
English, Chinese (Traditional and Simplified), Japanese, Korean, Spanish, French, German, Arabic, Hindi, Thai, Vietnamese and more. Switch language per recording, or let it work that out for you. Mixing two languages in one sentence is fine.

Works with no signal
On a plane, in a basement, anywhere the signal is bad — you can still type by talking. In offline mode, what you say stays on your phone.

Remembers your own words
Company names, people, products, jargon — add them to your list and Kio Flow gets them right every time.

Your usual sentences, one tap away
Greetings, follow-ups, meeting wrap-ups: save the things you type every day and drop them in with one tap.

Everything you said, easy to find
Every recording is kept, so you can search it, read it again, copy it, or clean it up once more.

Works on your Mac too
Same account, same talk-to-type on your Mac, with both sides in sync.

## Version history (last 5 releases)

### 1.3.16 — 2026-10-06

• Keyboard microphone: if Kio Flow has been closed, tapping the mic no longer looks like it's recording and then says no speech was detected. Within about 1.5 seconds you'll see the "Open Kio Flow" prompt — tap it and recording starts in the app.
• Stability and performance improvements.

### 1.3.15 — 2026-10-05

• English keyboard: fast typing no longer drops keystrokes — rapid spaces, double letters (ll, ee, ss), and two-thumb typing all register.
• Taps in the gaps between keys now go to the nearest key, and edge keys (Q, A, P, L, Shift, Delete) respond as soon as you press.
• Keyboard microphone recovery: after tapping "Open Kio Flow", recording starts right away and keeps going when you return to your app. No more getting stuck on "Preparing microphone…".
• New "Remove Filler Words" setting (off by default) cleans repeated fillers like um / uh on your device.
• Snippets and Vocab: clearer error messages that keep your draft, and a cleaner vocab editor.

### 1.3.14 — 2026-09-30

• Redesigned the Snippets and Vocab pages: a clearer list, favorites, and a sync status bar with one-tap retry if syncing fails.
• The add button now uses the Kio Flow theme color.

### 1.3.13 — 2026-09-29

• Refreshed the main screens and added offline access to snippets.
• Tap a transcript to copy it, or press and hold for more actions. Playback and word counts are more reliable.
• Improved recovery after keyboard recording fails and return to the previous app.
• Snippets and vocabulary now sync in the background and clear when you switch accounts.
• Improved free recognition limits and account deletion.

### 1.3.12 — 2026-09-23

• Fixed a launch crash on iOS 27 so the app opens reliably.
• Clearer free trial and pricing, with your remaining recognition quota shown on screen.
• Smoother keyboard, including more reliable return to your previous app.
• General stability improvements.
