User reviews

Finally, a TTS app that actually works

CastReader does exactly what it promises. Clean interface, natural voices, and the highlighting feature keeps me engaged. Whether it's a news article or a PDF document, it just works. Five stars.

Makes everyday reading easier

CastReader is a convenient way to catch up on articles when I don’t feel like staring at a screen. I like how simple it is to turn text into something I can listen to. Definitely worth trying!

Simple idea,big difference.

I still have the original text in front of me when I need it, but I don't have to keep my eyes fixed on every line. That combination works really well for me.

Great for English practic

Hearing the words while reading along has been helpful for pronunciation. I sometimes replay a difficult section at a slower speed.

Didn’t texpect to keep using it.

I’ve tried several reading apps and usually delete them after a day. This one has stayed on my phone because it fits naturally into my routine.
