TD Snap review
A free AAC foundation with eye-gaze, switch and scanning access, plus paid page-set upgrades.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TD Snap is augmentative and alternative communication software for people with speech and language disabilities, including autism, cerebral palsy and aphasia. It combines symbol-supported page sets with a text-based page set that includes a keyboard and word prediction. Communication can be accessed through touch, eye gaze, switch control or scanning, while customizable buttons, layouts, search, visual schedules, timers and scripts support different communication needs. It is available as a standalone app for Windows and iPadOS and is also included with selected Tobii Dynavox communication devices.
The free plan includes editing, sharing and syncing features, and the software supports offline use. Paid options are organized around specific content or speech additions: Gateway adds the Gateway page set, PODD adds the PODD page set, Metacom adds Metacom symbols and content, and Speaking Upgrade adds speech output. Speech features include synthetic and personal voice options. The published pricing structure makes TD Snap suitable for starting with core AAC functions before adding the page sets or speech capability that a communicator needs.
Access and ecosystem support are central strengths. Users can back up, share and synchronize customized content through myTobiiDynavox, while Google Assistant and YouTube are listed integrations. The software also supports search for words and symbols and offers fully customizable layouts, which can help tailor communication pages and visual supports. TD Snap is a strong fit for people who need broad access-method support and a free starting point; organizations or families requiring a specific premium page set, speech output, or a platform beyond Windows and iPadOS should assess the paid options and platform fit first.
