Speechify is absolutely brilliant. Growing up with dyslexia this would have made a big difference. I’m so glad to have it today.

Pros Cons
Testing out interactions as a designer It is for Mac users only and not for Windows users
Doing user testing Achieving more complex animations can be tricky if not impossible
The users they feel like they're using a real production app It would be great if there would be more straightforward features for these kind of effects.
