Recommended devices

Isaac AAC works on all devices, but for the best experience, we recommend tablets.

Recommended

Tablet 10"+

For maximum comfort and ease of use, we recommend a tablet with a 10-inch screen or larger. Larger buttons are easier to press, and symbols are more visible, making communication more natural and effective.

Smartphone

Isaac AAC is also available on mobile phones. It's a great option for travel or as a backup device. All features work exactly the same on a smaller screen.

Tip: Many families use a tablet at home and a phone while out. Isaac AAC syncs across all your devices.
