Start with the job you want help with. Do you need a way to communicate when speech is unavailable, words for a difficult request, or a reminder to follow up? These are different needs. An app described as an “autism communication app” may address only one of them.

This guide is published by tonen, which provides conversation wording support on iPhone. It is a selection checklist, not an independent product ranking or a claim that one app suits every autistic person.

Choose the category before the app

What you need	What to explore	What to test
A way to express yourself alongside or instead of speech	AAC, including text, symbols and speech-generating options	Can you communicate your own messages using an input method that works for you?
A starting point for a request, boundary or reply	Conversation scripts and editable wording tools	Can you change the words without changing your meaning?
A record of instructions or an agreed next step	Written notes, reminders or task tools	Can you find the information when you need it?
Time or a different format for a conversation	An agreed pause, written exchange or other communication adjustment	Will the other person respect that arrangement? An app cannot make them do so.

AAC means augmentative and alternative communication: ways to supplement or replace speech. It includes low-tech and high-tech tools, and someone may use a combination. It is not limited to people who never speak. The Communication Health Support Association’s AAC overview explains the options and how a speech-language professional can help with choosing and using a system.

A wording app is not a replacement for a reliable way to express yourself. If you need symbol-based or speech-generating AAC, evaluate that need directly. A paper board, written note or existing AAC system does not become less useful because another app has more features.

For a broader view of apps and non-app options, see communication tools for autistic adults.

Test one real situation

Choose a low-pressure example you recognise. For instance: “I miss parts of spoken instructions at work and want them written down.”

A starting line could be: “Could you send the steps in writing, including which one to do first?” The useful test is whether the tool helps you find and adapt that request. You do not need to sound warmer, make eye contact or apologise to make the request valid. See more scripts for asking for written instructions.

Try these checks before paying:

Your message: Can you say what you intend, including disagreement, refusal or a request to stop? Reject suggestions that add promises or apologies you do not mean.
Access: Is the text readable? Are controls easy to reach? Check contrast, text size, screen-reader support and navigation on your own device rather than relying on a “sensory-friendly” label.
Speed: Can you reach the relevant words when you need them? Try saving a favourite or keeping a simple note available.
Connection: Which functions work without internet? Test those separately from generated replies or other online features.
Cost: Check what is actually free, which limits apply, your supported device and the purchase screen’s local price.
Fallback: Keep another way to communicate if the battery, connection or app is unavailable.

For a repeatable trial, use the access and privacy checks. If you are preparing for an appointment, use the appointment note and conversation examples.

The other person also has a role: allowing time, using clear language and respecting your preferred format. You do not have to solve every communication difficulty with software.

Where tonen fits

tonen is for preparing and adapting words before a conversation, finding possible replies and reflecting afterwards. It is not a symbol-based or speech-generating AAC system.

Conversation scripts offer starting wording and tone choices. Reply Helper suggests possible replies; you decide what to send. Perspective Helper offers possible interpretations, not knowledge of someone else’s intentions. Debrief provides prompts for reflecting on a conversation. These suggestions can miss context or be wrong, so check them against what actually happened.

The free tools include 21 scripts, Box Breathing, 5-4-3-2-1 Grounding and one use each of Reply Helper, Perspective Helper and Debrief. Optional Premium adds the full script library, Phone Call Mode, Body Scan, Safe Place and 50 shared Helper uses per week. Check the App Store for local pricing and any eligible trial.

Check privacy feature by feature

An offline script library does not mean every function stays on your device. In tonen, bundled scripts and core Calm exercises work offline; Premium content still requires Premium access. Generating replies, perspectives, debriefs and custom scripts needs an internet connection. Read tonen’s privacy policy before entering personal information.

For any app, check what you submit, where it is processed, how long it is kept and what deletion options exist. Avoid including names or sensitive details that are unnecessary for the task. Do not assume that a “private” or “secure” label answers these questions.

What would make it useful for you?

Judge the tool against the task you chose: could you find your words, keep your meaning and use your preferred communication format? More features are not automatically better. You can keep using a simple note, combine tools or decide an app is not useful.

This guide does not claim that communication apps treat anxiety, prevent burnout or improve social skills. tonen provides practical wording support; it is not therapy or a substitute for AAC. Preparation can give you an option to try, but it cannot guarantee how another person responds.

Common questions

Can I use AAC if I sometimes speak?

Yes. AAC can supplement speech as well as replace it. The useful question is which communication methods are available and work for you in a particular situation.

Can I use scripts alongside AAC?

You can prepare wording and use your preferred way to communicate it. Do not assume an app connects to your AAC system: check compatibility and access needs separately.

Does tone choice change my voice?

In tonen, tone choices change the suggested wording. They are not a promise to change your spoken delivery or predict how someone will interpret it. Use only words that fit your meaning.

Do I need to practise aloud?

No. Reading, editing, typing or keeping a note available may suit you better. If you want to rehearse, you can read the words yourself or practise with someone you trust. There is no requirement to perform a particular speaking style.
