Many aphasia apps charge around $30 a month, or a few hundred dollars a year. Aphasia Studio is free to start — you can practice a wide range of exercises without paying — and offers an optional premium plan for people who want more at $14.99. If cost is a barrier, being able to practice for free every day matters.
There are also completely free websites. The best known is
Aphasia Therapy Online, a research project from La Trobe University: 11 task types across listening, reading, writing, and naming, a set of 566 words, three difficulty levels, 12 languages, and no sign-up at all. It is genuinely useful, and it is free because it is a research tool, not a maintained product.
That difference matters. A fixed free tool stays the same: the same 566 words, no account, nothing that follows you from day to day. Aphasia Studio's optional subscription is what funds the rest — 1,500+ words with new content added all the time, saved progress you can show your SLP, four difficulty levels that remember where you are, a practice plan with homework that adjusts as you go, your own words and photos in My Words, and Match, Speak, and Type modes on the core exercises. Free gets you started either way. The subscription is what keeps a tool growing with you.
