Sayella vs TD Snap
TD Snap, from Tobii Dynavox, is a very capable AAC app, and for communicators who need eye-gaze or a dedicated device it is one of the strongest options there is. If you are weighing it up against Sayella, the real differences come down to three things: what it costs to start, whether you want to stay free of a hardware ecosystem, and whether your words can travel with you.
The short answer
TD Snap is powerful and widely used in clinical and funded-device settings, with excellent support for eye-gaze and dedicated Tobii Dynavox hardware. Sayella takes a simpler, affordable path: a full, offline talking board for free, forever, running on iPhone, iPad, Android and the web from one account, with no device or ecosystem lock-in. If you need eye-gaze, dedicated hardware or heavy clinical support, TD Snap is the stronger pick. If price, simplicity and freedom from a hardware ecosystem matter most, that is the gap Sayella was built to close.
