Inclusive Info Hub

In the early 1960s, a freshman engineering student named Barry Romich met Ed Prentke, an engineer working at a Cleveland hospital, and the two discovered they shared the same mission: helping people with disabilities communicate. That meeting eventually became the Prentke Romich Company, now part of PRC-Saltillo, and more than six decades later, that same lineage sits behind TouchChat, one of the most clinically established AAC apps a family can buy today. At Inclusive Info Hub, we look at company history because AAC is not a purchase families make lightly, and knowing whether a company will still exist to support an app in ten years matters as much as any single feature.

In a special education classroom outside Toronto, a therapist described a student with cerebral palsy and an intellectual disability who could not reliably tap a touchscreen at all. Switch scanning through TouchChat became the first system that let him build sentences independently, without needing constant hand over hand support from an aide. That access flexibility, more than any single vocabulary feature, is what sets this app apart from most others on this list.

The Story Behind TouchChat

PRC was founded in 1966 out of Barry Romich's basement in Madisonburg, Ohio, initially building a communication typing system out of a discarded Teletype machine before moving to its first real facility in Shreve, Ohio in 1973. Decades of hardware innovation followed, including some of the earliest scanning environmental control devices and eye tracking systems in the AAC field. In 1996, Dave Hershberger, who had started working at PRC as a teenager, founded a sister company called Saltillo with Romich's support, eventually merging back into what is now PRC-Saltillo in 2019.

TouchChat itself has a specific historic distinction: when Saltillo introduced it in 2010, it became the first app released by any speech generating device manufacturer, marking the industry's shift from dedicated hardware toward tablet based software. The WordPower vocabulary bundled into TouchChat HD was designed by speech language pathologist Nancy Inman, built around a word based approach intended for fast, intuitive sentence construction rather than relying purely on preset phrases.

It is worth noting directly, in the spirit of never softening a limitation: in September 2024, PRC-Saltillo began notifying individuals affected by a data breach involving sensitive personal information. For a company handling data connected to children's communication needs, this is a fact families deserve to know before entrusting the app with a loved one's daily use.

Platform Clarification — iPad Only, Confirmed

Apple App Store: Search "TouchChat HD- AAC w/ WordPower," published by Prentke Romich Company. The base version is priced at $149.99, with an expanded universal bundle covering iPad, iPhone, and Mac with additional language and voice options priced at $299.99.

Google Play Store: Not available. TouchChat has no Android version and none has been announced.

This app runs on Apple hardware only, and families researching AAC for an Android tablet or phone will need to look elsewhere on this list.

What TouchChat Actually Does

TouchChat gives users a customizable vocabulary file made up of pages and buttons representing words, phrases, sentences, and functions, spoken aloud through a built in voice synthesizer or a recorded message. Vocabulary files are fully customizable across page layout, grid size, button actions, and symbols, with access to more than 45 button actions and nearly 40,000 SymbolStix symbols. PCS symbols, a widely used alternative symbol set in AAC, require a separate in-app purchase to unlock.

Key Features in Full Detail

WordPower Word-Based Vocabulary

Designed by SLP Nancy Inman, WordPower organizes vocabulary around flexible, high frequency words rather than static preset phrases, aimed at helping users build grammatically complete, spontaneous sentences instead of relying on memorized requests.

Switch Scanning and Alternative Access

TouchChat supports single and multi-switch scanning alongside standard touch access, extending usability to individuals with motor impairments who cannot reliably tap a screen directly, a genuinely important option for users whose intellectual disability is accompanied by physical access challenges.

Multi-Language Vocabulary Support

The base bundle includes English, Spanish, French, and Mandarin vocabulary options, with additional languages including Hebrew, Arabic, and Canadian French available for purchase through the in-app Upgrade Store, along with code switching support that lets multilingual users blend languages within the same speech display bar.

Adjustable Button Activation Timing

Timing for how long a button must be pressed before activating can be tuned to a specific user's motor control needs, reducing accidental selections for users with limited fine motor precision, similar in spirit to the touch accommodation settings found in other apps on this list.

Smart Contextual Navigation

TouchChat can automatically jump to a relevant page based on context, for example moving directly to a food selection page when a user presses "eat," reducing the number of steps between an intention and the words to express it.

Multiple Voice Options

Users can choose among synthesized voices from Acapela, Almagu, and Apple's own text-to-speech engine, letting a user select a voice that feels like a genuine extension of their personality rather than a generic robotic default.

Gesture Based Navigation

Beyond tapping, gestures can be used to move between pages or speak messages, giving more experienced users faster ways to communicate without hunting through menus.

Pricing — Complete and Honest

The base TouchChat HD - AAC w/ WordPower app is $149.99 as a one time purchase, notably lower than the $249.99 Proloquo2Go asks for, though still a significant investment for most families. The expanded universal bundle covering iPad, iPhone, and Mac with a broader language and voice selection runs $299.99. Additional vocabulary files, symbol libraries such as PCS, and extra languages are sold separately through the in-app Upgrade Store, meaning the sticker price is often not the final total cost once a family customizes the app to their specific needs.

Who TouchChat Is Built For

Users With Motor Impairments Alongside Communication Needs

Switch scanning support and adjustable activation timing make TouchChat one of the stronger choices on this list for users whose access needs go beyond simple tapping.

Multilingual Households and Clinics

With code switching support and multiple purchasable language packs, TouchChat serves multilingual families and international clinics more directly than several competitors.

Special Education Teams With Existing PRC-Saltillo Training

Schools and districts already using PRC-Saltillo's broader ecosystem of devices and training resources often find TouchChat integrates naturally into an existing clinical workflow.

Users Progressing Toward Spontaneous, Grammatically Complete Speech

WordPower's word based structure is aimed specifically at users ready to move beyond fixed phrases toward flexible, self-generated sentences.

TouchChat vs GoTalk NOW — The Practical Comparison

Both apps are iPad only and come from companies with deep AAC hardware history, but they serve different priorities.

TouchChat costs more, starting at $149.99 and reaching $299.99 for the full multi-language bundle, and offers more advanced access options including switch scanning and multi-language code switching, built around WordPower's flexible core vocabulary approach.

GoTalk NOW costs less at $119.99, offers scene based communication pages that TouchChat does not have, and includes Attainment's free public template gallery, though its access method support does not extend as far into complex motor access needs.

For users needing multilingual support or more advanced switch access, TouchChat is the stronger fit. For families on a tighter budget who want scene based, photo grounded communication pages, GoTalk NOW is the more approachable option.

Honest Limitations

Reported crashes and memory leaks affect some users. Multiple App Store reviews describe the app freezing constantly after a recent iPad or app update, with PRC-Saltillo support acknowledging a known memory leak issue in at least one documented case. This is a real risk worth knowing about before spending $150 to $300 on an app that some users report becoming unreliable.

Vocabulary layout changes between skill levels. At least one special education reviewer noted that as a user progresses to a more advanced vocabulary level, key button positions like "home" or "clear" can move to entirely different corners of the screen, forcing the user to relearn basic motor patterns they had already built.

The app saves a daily logo image to the device's camera roll. One detailed reviewer specifically flagged this as an unexpected and unexplained behavior, worth being aware of for families concerned about their device's photo library filling with app generated images.

PRC-Saltillo disclosed a data breach in September 2024. The company began notifying affected individuals about a breach involving sensitive personal information. Families should factor this into their comfort level with the amount of personal data an AAC account may store.

No Urdu or South Asian regional language support. TouchChat's language expansion has focused on Spanish, French, Mandarin, Hebrew, and Arabic, with no current Urdu, Hindi, or other South Asian language option available.

Frequently Asked Questions

What This Means for Users in Pakistan and Across Asia

TouchChat is not region locked, so families in Lahore, Karachi, or Islamabad can purchase and download it the same as anywhere else, but the combination of iPad-only hardware requirements, a $149.99 to $299.99 price range, and no South Asian language support makes it one of the least regionally accessible apps on this list. For Pakistani families specifically, Avaz AAC's regional pricing and language depth, or Cboard's fully free open source model, will generally be more realistic starting points than TouchChat, which is better suited to families and clinics already working within a Tier 1 market's AAC ecosystem.

A Closing Thought

Six decades separate a discarded Teletype machine in a Cleveland hospital from the iPad app families download today, and that lineage shows in TouchChat's clinical depth and switch access sophistication. It also shows in the growing pains of a large, long running company, from reported crashes to a 2024 data breach. TouchChat remains one of the most capable AAC tools available for users with complex access needs, but capability and reliability are not always the same thing, and families deserve to weigh both honestly before committing.
