TD Snap, from Tobii Dynavox, is the software behind some of the most capable AAC hardware in the world — including eye-gaze devices. Since 2024 it's subscription-only on the App Store at $9.99/month, the same price as Tala. So the choice isn't about money; it's about fit.
Here's where each app shines.

This is TD Snap's home turf. If your child needs eye-gaze access, switch scanning, or may graduate to a dedicated Tobii Dynavox device, TD Snap gives you one ecosystem across all of it. No other consumer app matches that hardware path.
Tala is a touch-first iPad and iPhone app. It doesn't do eye gaze — and if that's what your child needs, TD Snap is the better call.
TD Snap's Core First page sets are thorough and school-proven, but the app is built for professionals: page set choices, grid sizes, and access settings take time to configure well.
Tala is deliberately simple: 10 ready communication boards, whole-phrase cards a child can use immediately, and a 90-second setup a parent does alone. For families starting AAC without a support team, that difference matters more than any feature list.
TD Snap uses standard synthetic voices across its supported languages. Tala ships one natural, human-sounding voice per language across all 14 — because a child's first "I love you" through AAC shouldn't sound robotic.
Choose TD Snap if your child uses or may need eye-gaze or a dedicated Tobii Dynavox device, or your school district standardizes on Core First.
Choose Tala if you're a family starting out on an iPad, you value natural voices and whole-phrase cards, or your home language is one of Tala's 14.
The best AAC app is the one your child will actually use every day.
