About

AEIOU

Features
Read full description

AEIOU is a free, intelligent communication keyboard for people who can't speak, or can't speak as easily as they'd like to. Built for iPhone and iPad and designed to understand the moment you're in, so what you want to say is often one selection away. Everything runs on your device. Select with a tap, a blink, or any external switch. AEIOU learns how you communicate and gets faster the more you use it. WHAT'S DIFFERENT ▸ PREDICTIONS THAT UNDERSTAND THE MOMENT AEIOU combines a built-in language model, Apple's on-device intelligence, your own history, the time of day and what was just said to you. Switch on the optional extras below and it also knows where you are, what's coming up, what you can hear and what's in front of you. ▸ A SMARTER WORD PREDICTOR A language model inside the app reads the sentence as you spell it and offers the likeliest next words. Fewer letters to find. Fully offline. ▸ GUIDED SETUP A short questionnaire explains each feature and sets everything up for you. Permissions are only requested when you choose a feature that needs one. ▸ OPTIONAL AWARENESS, ALL ON YOUR DEVICE (every one off until you switch it on) • Listen: hears what the other person says and suggests replies you can pick instead of spelling them out • Notice sounds: a doorbell, a ringing phone or an alarm becomes a suggestion • What's around me: the back camera notices everyday items brought to the table ("which one do you want?") and offers replies to them • Places: save Home or the GP surgery and suggestions fit where you are • Calendar and Reminders: "I have something on today", "Is it time for my medication?" (event and reminder titles are never read out or stored) • Contacts: recognises the names of people in your life • Movement and phone state: still or travelling, charging overnight • Apple Watch: optionally uses your heart rate as one more hint for suggestions. It isn't a medical feature, never diagnoses anything and must never be relied on for safety ▸ LEARNS WHAT YOU SAY, WHEN It remembers the answers you usually give and offers them first. A carer can teach it replies too. Reset everything it has learned at any time. ▸ SELECT YOUR WAY Rows scan automatically and any tap, blink, switch or key press selects. Prefer to point? Switch on "Tap letters directly". Blink detection ignores reflex blinks. ▸ PERSONAL VOICE READY On iOS 17+, AEIOU can speak in your own voice, recorded once in iOS Settings. ▸ KIND TO YOUR BATTERY When the phone is warm, the battery is low or the app is idle, AEIOU eases off the optional camera and sound features. Typing and speaking keep working. ▸ PRIVATE BY DESIGN No accounts, no analytics, no tracking, no ads. Audio and camera frames are processed in memory and never recorded or sent anywhere. Optional iCloud sync carries only pinned phrases, recent sentences and settings between your own devices. WHO IT'S FOR People with ALS/MND, cerebral palsy, stroke or aphasia, autism with limited verbal speech, post-laryngectomy or intubation recovery, selective mutism, or any condition that makes speaking difficult. Also carers, family members and conversation partners. It's free. There are no in-app purchases, no ads and no subscription. Anyone who needs it can have it. REQUIREMENTS • iPhone or iPad on iOS 17 or later • TrueDepth front camera for blink detection (optional: every other input method works without it) • Apple Intelligence on supported devices for extra generated suggestions (optional) • Every sensor feature is optional and asks permission only when you switch it on • No internet connection needed Made with care. Designed to give you back the words.
