How TWIYO 1.3.5 works (September 2026) — from the home screen to the communication board. In plain language, using the button names from the app.

Getting started

Open TWIYO

Go to twiyo.app in Safari (iPhone/iPad), Chrome (Android), or another browser on phone, tablet, or computer. Top right, choose the language (NL or EN). Tap “Open app” to reach the app home screen.

Add TWIYO to your home screen

TWIYO is a web app: no app store, but an icon on the home screen. After that it feels like a real app. On twiyo.app you see the steps for your device. → iPhone or iPad in Chrome: tap Share in the address bar at the top → Add to Home Screen. → iPhone in Safari: tap Share (usually at the bottom) → Add to Home Screen. On iPad, Share is at the top. → Android: in Chrome open the menu (⋮) → Add to home screen or Install app. Then open TWIYO from that icon — especially after paying or signing in. Premium can stay invisible if you only use a browser tab.

What you see on the home screen

The home screen is titled “Choose a category”. From top to bottom: → Communication board (Premium) — “Tap images to speak” → Themes such as Animals and Food & Drinks, each with “Learn” and “Play” (free) → Counting games and Alphabet & Phonics (free) → Speller board, Word-picture, and Progress & insights (Premium) Premium items show a small Premium badge until your trial or subscription is active. Top right: gear (parent panel), language, and “Calm”.

Word game: Learn and Play

Pick a theme

This is the free word game: you hear the word and pick the picture. By default only Animals and Food & Drinks are on (Beginner preset). Other themes: Nature, Home, Instruments, Colors. → That is different from the Premium “Word-picture” card lower down: there you see the written word and pick the picture. → Which themes your child sees: on the home screen “Edit” (PIN) → a switch per theme, or presets “Beginner” / “All”.

Learn first, then play

Each theme has two buttons: → “Learn”: calmly browse all pictures; tap a card and TWIYO speaks the word. → “Play”: “Where is the …?” — pick the matching picture from four options.

During the game

At the top you see your progress. TWIYO shuffles words each session so the same word does not keep coming back-to-back. After a correct answer you sometimes get confetti. Back to the home screen: the “Back” button at the top left. Set the number of rounds under Settings → “Games” tile.

A calm start with the word game

Settings for a calm start

The word game (Learn + Play per theme) is free. For a calm start: → Home screen → “Edit” (PIN) → Beginner preset (Animals + Food & Drinks only) → Rounds per game: parent panel → Settings → “Games” tile → 5 (later 8–10) → Words use lowercase with school-style a and g (Poppins reading font)

Week 1 — animals

Open Animals → Learn and calmly browse the cards. Then Play with 5 rounds. Start with familiar words: dog, cat, cow, horse — then expand to elephant, bird, sheep, etc. Short sessions (4–6 words) work better than everything at once.

Week 2 — food & drinks

Same approach with Food & Drinks. Practice first: apple, pear, bread, egg — then pizza, soup, biscuit. All built-in words in this category: apple, raspberry, pie, pizza, potato, biscuit, broccoli, bread, cucumber, cracker, pear, soup, salad, strawberry, tomato, egg.

Week 3 — custom words

Add personal words via Parent panel → “Words & Images” tab (your photo, lowercase). For a calm start, up to five: → milk, water, banana, cheese (Food & Drinks category) → pet name (Animals category) Optional: record the word + “Where is the …?” in your voice. Free up to 10 custom words; Premium unlimited.

More in the app

Counting and Alphabet & Phonics

Both are free, below the theme cards on the home screen. → Counting games: “How many?” (count and pick the number), “Pick the amount” (number → matching group), “Count along” (tap each picture). → Alphabet & Phonics: “Letter Recognition”, “Letter Sounds”, “First Letter”, “ABC Order”.

Communication board (AAC)

Here your child “talks” with pictures. This is Premium — start a 14-day trial first (no payment details). AAC is learned best with a speech therapist; the trial is to see if the board fits, not to teach it on your own. → “Quick Tap”: each tile is spoken right away. → “Build Sentence”: tiles go into a sentence at the top; tap “Speak” to hear the full sentence. The top bar is yes, no, stop and I need help. “I want” and “I feel” sit on the tabs. → Search, recent and favorites (star in edit mode) help you find tiles. Tabs (Beginner shows a subset): My day, Core words, I want, I feel, Yes / No / Help, People. Extra tabs: Actions, Numbers, Food & drinks, Places. Body, clothes, school and transport packs stay off until you turn them on in edit. See the next block for folders such as Food and Drinks.

Folders on the communication board

Some tiles open a folder (subpage) instead of speaking right away. → Food & drinks → folders “Food” and “Drinks” → People → “Family” and “Others” → Places → “Home” and “Outside & trips” By default a folder opens as a popup with a close button. Prefer a back button? Parent panel → Settings → “Communication board” tile → “Open subpages as” → “Sub-navigation (back button)”. On “My day” you also pick the location there: Home or Day program. In edit mode you can add your own folders and tiles.

Speller board and progress

Both are on the home screen and are Premium. → Speller board: tap letters, then “Speak”. Defaults to lowercase (abc); top right, switch to uppercase (ABC). Layout: “A→Z” or “QWERTY”. Dutch also has “ij” / “IJ”. → Progress & insights: what has been practiced (games, score, play time).

Word-picture (written word)

At the bottom of the home screen there is a separate Premium card “Word-picture”: “Pick the picture for the written word.” That is reading practice — not the same as Learn/Play per theme (there you hear the word). Pick one category, or mix later. Difficulty (number of choices) applies here; in “Where is …?” there are always four pictures.

Sound in the word game

In Learn and during Play your child hears the word or “Where is the …?”. Order: your recording first (if you made one), otherwise the built-in voice or text-to-speech. Turn sound off: parent panel → Settings → “Speech” tile → turn off “Sound on”. On AAC tiles you do not record your voice; you use phonetic pronunciation there.

Personalization: photos, voice, and celebrations

Add a photo to a word

Parent panel (gear + PIN) → “Words & Images” tab → + new word or tap an existing word. → Tap the image: camera, gallery, “Online search” (Photos or Pictograms), or “Paste link” (needs internet). → Pick a category — then the word appears in Learn/Play (free up to 10). Photos stay only on this device.

Record your own voice

Open the word in “Words & Images”. Under “Audio recordings” you see two buttons: → The word itself — in Learn (“this is …”). → “Where is the …?” — in Play. Tap record, speak calmly, stop, and play back. Your recording overrides the default voice. You cannot record per tile on the communication board.

Link word game and AAC

With Premium you can link words and AAC tiles (one photo, one word): → Words & Images → “Also on communication board (AAC)” + “Place on communication board” (tab or folder). → Or on the AAC board: new tile with a photo → “Also in word game” + category. Edit linked words via Words & Images; standalone AAC tiles via “Edit” on the board.

Phonetic pronunciation (AAC tiles)

Does the voice mispronounce a word or name (e.g. “school” or “Jax”)? Type how it should sound. → Communication board → “Edit” + PIN → tap a tile. → In “NL pronunciation (phonetic)” and/or English: e.g. sgool or jax. The label on the tile stays “school” or “Jax”. → The first phonetic playback needs internet; later it is often cached. Without phonetic: built-in tile audio or the app voice. → On the communication board, “Online search” defaults to Pictograms (ARASAAC). In the word game you can still record your own voice — that applies there, not on linked AAC tiles.

Child's first name (welcome)

With Premium: parent panel → Settings → “Subscription” tile → “Parent account” → “Child’s first name”. → On the play screen: a large “Hi [name]!” → After a game: “Great job, [name]!” The name stays on this device and is cleared when Premium ends.

Celebration after a game

Parent panel → Settings → “Speech” tile → “Celebration after a game” (Premium): → Celebration sound: your voice, e.g. “Great job!” (max. 15 sec). Replaces the default cheer. → Celebration photo (optional): a recognizable photo in the circle under the confetti. Tip: say your child’s name in the recording. Everything stays local and is included in backup.

For parents: settings

Open the parent panel

In the app: tap the gear icon at the top right. You see “Parent Access”. Enter the PIN and tap “Unlock” (default 1234 — change it right away under the “Privacy” tile). Without the PIN, your child cannot change settings. No Premium yet? On the PIN screen you can already sign in with email (parent account) to restore a subscription — no PIN needed for that.

Words & Images

After the PIN you see two tabs: “Words & Images” and “Settings”. The first tab lists all your custom words. Tap one to edit, delete, or re-record. Free: up to 10 words; Premium: unlimited. You can also add a word from the home screen via “Edit” → “+ Add” (same PIN).

The eight settings tiles

The “Settings” tab is a grid of tiles (not one long list). Tap a tile to open it: → Subscription — trial, Premium, parent account, org code → Word packs — export, import, organisation packs → Backup — download, merge, or replace all → Speech — “Sound enabled”, speech speed, celebration after a game (Premium). One child-friendly voice; no male/female/child picker. → Games — difficulty, rounds, tile size; turn categories on/off in the app itself (see below) → Communication board — My day location, how folders open, grammatical order → Display — speech language, “Keep screen on” (on by default), Calm mode, high contrast, reduced motion → Privacy — wipe data, cookies, “Change PIN code” Calm mode is also “Calm” in the app header.

Switch language

The NL/EN button in the header switches the app language (buttons, words, voice). The same toggle works on the website. Under Settings → “Display” tile you can also pick a speech language.

Choose visible categories

You turn tabs and themes on or off in the app itself (no longer via a long list in Settings). New installs start with Beginner. → Word game: home screen → “Edit” (PIN) → a switch per theme. Presets “Beginner” / “All” sit above. → Communication board: “Edit” (PIN) → a switch per tab. The same presets sit above the tabs. → Beginner word game: Animals + Food & Drinks. Beginner AAC: My day, Core words, I want, I feel, Yes / No / Help, People. → Extra AAC tabs for body, clothes, school and transport stay off until you turn them on in edit. The “All” preset does not turn those packs on by itself. The “Games” tile in Settings only links to these screens.

Add tiles to the communication board

Go to the communication board (Premium). Top right: “Edit” + the same PIN as in Settings. → First open the tab (or folder) where the tile belongs. New tiles go into whatever is open. → In “Build Sentence”: next to yes/no/stop/help you can use + to add short phrases. Favorite: star in edit mode. → Tap the + box. “New tile” screen: Dutch and/or English, optional “NL pronunciation (phonetic)”, emoji or photo (camera, gallery, Search online in Pictograms, or Paste link) → “Add tile”. Optional: “Also in word game” (with a photo). → Tap an existing tile to change text, photo, or phonetic spelling. Words linked from the word game: via Words & Images. → Drag tiles to reorder. Tap “Done” so your child sees the normal board again. Missing a tab? Turn it on via “Edit” on the communication board.

Backup to another device

Photos, words, and AAC live on this device. There is no automatic cloud sync. → Premium on one device: “Save emergency copy”. On a new tablet, restore Premium with your email and choose “Restore emergency copy”. → “Download backup” keeps everything in a file on this device. On the new device: merge or replace all. The parent PIN is not included in the emergency copy. Getting packs from a day program? See “Organisation code” under Help.

Premium, Family and trial

What is free?

Free: word game per theme (Learn + Play), up to 10 custom words with photos, Counting games, Alphabet & Phonics, and most settings. Premium and Family unlock the same extras: Communication board, Speller board, Word-picture (written word), Progress & insights, unlimited custom words, first name, and celebration after a game. The difference is how many devices you can use at once.

Try or subscribe

Start 14 days of Premium with no payment details: parent panel → Settings → “Subscription” tile → “Start 14-day trial”, or via Subscribe on the website. During the trial you see “Premium trial: … day(s) left.” at the top. Still unsure about AAC? Extend once by 14 days: “Extend trial”, confirm your email with a code. You get a reminder 3 days before it ends and on the day Premium stops — no newsletter. Then choose Premium or Family, monthly or yearly via Stripe. Cancel: “Manage or cancel subscription” (signed in with the same email).

Premium or Family

Both plans unlock the same Premium features. The difference is how many devices you can use at once. → Premium: €4.99 per month or €54 per year — one device. → Family: €7.99 per month or €79 per year — up to three devices, for example home and school, or two children on separate tablets. → Subscribe at twiyo.app/en/subscribe. Choose Family if you need more than one tablet at the same time. → The same words on more than one device: merge backup in Parent settings. There is no automatic cloud sync for home use. → More than three devices, a practice, or a school: request an organisation quote via twiyo.app/en/professionals.

Parent account and restore subscription

Just paid or switching tablets? Parent panel → Settings → “Subscription” tile → “Parent account”: Stripe email, code by mail, sign in. Premium is then linked to this device. → If it does not show: “Restore subscription” (same email + code). Then open TWIYO from the home screen icon, not only a Safari tab. → “Manage or cancel subscription” (Stripe) only works when signed in with the payment email. → Switching devices: “Release license on this device” on the old one, or the seat stays taken (Premium = 1 device, Family = 3).

Help and questions

Does it work offline?

Yes, mostly — after the first load. Offline: word game, Counting, Alphabet, built-in AAC audio, your recordings on words, and phonetic tiles (after the first time with internet). Premium checks online now and then whether your subscription is still active. Internet is needed for paying, signing in with a code, Search online, phonetic AAC the first time, and “Speak” on the speller board.

More questions?

On this website (not in the play screen) the “AI help assistant” sits at the bottom right: short FAQ answers, plus a button for an idea. Also: FAQ, terms, and privacy. Still stuck? Contact page or info@twiyo.app.

Organisation code (pilot / day program)

Did the day program, school, or speech therapist give you an org code? Parent panel → Settings → “Subscription” tile → “Link organization”: name this device (e.g. iPad Dolphin group) and enter the org code → “Link”. Then you can install shared packs under the “Word packs” tile. Without a code you can skip this — at home you use the normal trial or Premium.
