Sometimes just giving a hint or context is all your listener needs to understand you. The first letter or two. The general topic. AlphaTopics is the perfect AAC app for people whose natural speech is not always clear. Stop wasting time navigating to the right word or typing it out. Get your point across faster by touching just the first few letters of the words you say. Give your listener context by starting the conversation with the topic. Write it out with your finger or draw a picture. Don’t let overly complicated apps slow you down. Tactus Therapy, a trusted name in speech therapy apps, brings you a new take on a classic communication tool. AlphaTopics includes 3 AAC communication boards loaded with features: 1) Letter Board - 26 letters in alphabetical order or 2 variations of frequency order - 10 single digits allow you to express any number - Vowels highlighted and aligned for faster navigation - Natural or automated speech reads out the name of each letter or number - Yes, no, question, smiley, space, and backspace buttons for prosody and function 2) Topic Board - Fully customizable text you can re-order - Voice output with adjustable speech rate - Two sizes of grid to display 12 or 24 topics - Pre-filled with functional topics for adults 3) Whiteboard - Write or draw on the screen - 6 colors and 4 widths - Export to Photos or e-mail When used together, alphabet and topic boards have been scientifically shown to make the speech of people with motor speech disorders far more understandable. Combined with the whiteboard, these tools help people with aphasia express themselves more clearly with self-cueing and strategy use. Stroke, traumatic brain injury, cerebral palsy, Parkinson’s disease, ALS, and motor neuron disease are all conditions that can impair speech production. Pointing to the first letter in each word not only gives the listener more information about the word, it also encourages the speaker to slow down and separate words, actually making the words clearer! Using alphabet supplementation, studies show intelligibility of sentences improves 25% on average. Pointing to the topic before speaking narrows the range of possibilities for the listener, giving context. Studies show using a topic cue improves word understanding by an average of 28%. Topics can also be used by people with aphasia, a language disorder, to help pinpoint the intended message. Additional Features: *Adjustable settings for visual, physical, language, and cognitive impairments *Works with built-in scanning and guided access *4 color schemes *Pick which board comes up when you start the app *Export any board you've customized to print or share "People whose speech is hard to understand often just want to provide extra clues to their listener and don’t require all the features of a comprehensive AAC app. It’s terrific that we now have an app that provides this level of support on a mobile platform.” - Lois Turner, SLP & AAC specialist Visit tactustherapy.com for more information on how to use this app, the evidence to support this form of AAC, and a day-by-day account of how this app was made.

Verdict

The call

The clearest difference is price: Lingraphica Device Assessment at Free against AlphaTopics's $9.99. Lingraphica Device Assessment also leads on update cadence (every 5 months vs every 11 months) and review sentiment (50% vs 40%). AlphaTopics's advantage is rating (4.3 vs 4.0) and ratings volume (46 vs 5). On ads, in-app purchases and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AlphaTopics holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: AlphaTopics has 46 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Lingraphica Device Assessment's written reviews are positive against 40% of AlphaTopics's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lingraphica Device Assessment ships an update every 5 months, AlphaTopics every 11 months. The most recent releases landed on October 16, 2026 and October 21, 2026 respectively.
