A free picture communication app for toddlers. Tap a picture. Hear a word. Build a sentence. Whether your child is non-speaking, late-talking, or just beginning to string their first words together — Swirly AAC gives them a voice. A COMMUNICATION TOOL FOR EVERY TODDLER Babies who learn sign language often speak earlier than those who don't. The same principle applies here. Giving a pre-verbal toddler any way to communicate doesn't slow speech down — it speeds it up. Every successful exchange teaches a child that words have power. It works beautifully for typically developing toddlers building their first phrases. It works for children with autism, Down syndrome, childhood apraxia of speech, or any reason spoken words aren't coming yet. It was designed for both, because communication is for every child. TWO MODES, ONE APP Standard AAC — Symbol Grid A bold, colorful picture grid with core vocabulary every toddler needs: feelings, food, people, actions, places, routines. Tap symbols to build a sentence, then hit Speak. Includes Visual Scene Display — tap objects inside illustrated scenes of a playground, kitchen, and bedroom. A research-backed approach for very early communicators who respond better to context than isolated symbols. Grammar Tree — Sentence Builder Guide your child through their first full sentences. Choose "I want" → "to eat" → "cookie" and the app speaks the whole phrase. A child who can't yet sequence words independently can still generate a real, novel sentence. Greetings, requests, observations, feelings — all here. RECORD YOUR OWN VOICE Tap any symbol and record mom, dad, grandma, or a sibling saying the word. Now the tablet sounds like home. Free, like everything else. MAKE IT YOURS Add a real photo of grandma. Hide words your child isn't ready for. Reorder the board. Add custom symbols. Everything editable in two taps from the main screen. BUILT FOR REAL FAMILY LIFE Fully offline — works on a plane, in the car, at grandma's house. No sign-in required. No ads, no subscriptions, no paywalls — free. Nothing leaves the device — no server, no analytics. Backup and restore — export a single file, import it anywhere. FOR FAMILIES AND SPECIALISTS Designed around core vocabulary principles used by speech-language pathologists in early intervention. Suitable alongside — not instead of — a qualified SLP. Appropriate for: autism spectrum disorder (ASD), childhood apraxia of speech (CAS), Down syndrome, cerebral palsy, hearing loss, selective mutism, language delay, speech delay, late talkers, pre-verbal toddlers, and typically developing toddlers from 18 months. ABOUT SWIRLY STUDIOS Developed by parents and educational technologists, Swirly Studios has been building free, friendly software for families since 2011 — rooted in a genuine belief that every child deserves the tools to make themselves understood. We hope Swirly AAC gives your child a little more voice, and your family a little more connection, from the very first tap.

GridNote is a weekly schedule and session-notes app for school speech-language pathologists. Try it free for 7 days. After that, unlock once through Apple. The same unlock covers iPhone, iPad, and Mac. Sign in with the same Apple ID and your caseload syncs through that Apple ID’s private iCloud — open a note on your phone, see it on the Mac. If you already bought GridNote as a paid app, you stay unlocked. Keep a color-coded Mon–Fri therapy grid, tap a student to document a session, and track Medicaid-style billing status without sending claims anywhere. SCHEDULE • Monday–Friday lined time grid from about 8:10 AM • Therapy, group therapy, planning, lunch, duty, Child Find, and specials • Tap a day name to mark holiday, no school, out of office, PD, or snow — that date only • Copy a repeating week from another school year • Duplicate a block while editing • A green check means notes or goals are saved; billed is a separate mark SESSION DOCUMENTATION • Date, start/end, minutes, service codes (92507, 92508, Evaluation, Absent, Other) • New notes fill activity and materials from the last matching student note • Goals, notes, materials, and billing: Pending, Billed, No, or NB • Copy notes or Copy for Google to paste into a district form you already use STUDENTS AND BILLING • Caseload pages with IEP goals and session history • End of day: who’s left to bill, plus sessions scheduled with no note yet • History with CSV export Your caseload starts empty so you can add your own students. Open Settings → Load Demo Caseload only if you want a fake sample week to explore (it replaces anything already in this caseload, including other devices if iCloud is on). GridNote does not have its own login. Sync uses iCloud on this Apple ID. It is not a medical device and is not a Medicaid payer connection. Changes save on the device right away, then iCloud syncs when you are signed in.
