About

ComBoard AAC

Features
Read full description

ComBoard helps people who can't rely on their own voice say exactly what they mean — by tapping, dictating, or even just looking. It's a full augmentative and alternative communication (AAC) app built to be simple, warm, and genuinely accessible. TRY IT FREE, THEN ONE PRICE — NO SUBSCRIPTION, EVER. Use every feature free for 14 days. After that, a single one-time purchase unlocks the whole app forever — on all your family's iPhones and iPads, with no subscription, no ads, and no recurring fees. AAC shouldn't cost thousands of dollars or lock your child's voice behind a monthly bill. The voice your family depends on should never expire because a payment lapsed. BUILT FOR EVERY ABILITY • Big, clear keys — large, high-contrast targets are easy to hit, with fewer mis-taps for limited mobility and motor differences. • Speak it out loud — tap Speak and ComBoard reads your message in a clear, natural voice. • Dictate by voice — tap Listen and speak; your words become text you can edit and say. • Hands-free with your eyes — works with Apple's built-in Eye Tracking (iOS 18+): look at a key and hold your gaze to select it, no touch required. • Smart word prediction — suggestions that learn the words and phrases YOU use most, getting faster over time. • Words or emoji — switch the board between letters and emoji with a single tap. • Make it yours — 13 color themes including color-blind-safe palettes, plus adjustable text sizes. • Quick Yes / No — instant answers for everyday moments. PRIVATE BY DESIGN ComBoard collects nothing. No accounts, no analytics, no tracking. Your learned words live only on your device, speech is synthesized on device, and dictation is processed on device wherever supported. Nothing about how your family communicates is sent to us — because we never receive it. WHO IT'S FOR Nonverbal and minimally verbal children and adults, and anyone living with autism, apraxia, aphasia, ALS, stroke, cerebral palsy, or other conditions that affect speech — plus the parents, carers, teachers, and speech-language therapists who support them. Free for 14 days, then unlock everything with a one‑time purchase of $49.99 — not a subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Tap. Speak. Connect. One voice, one price, forever.
