The free tier covers 10 minutes per session and 30 minutes per day. CastSound Pro is available inside the mobile app as a Weekly ($2.99), Monthly ($6.99), or Yearly ($29.99) subscription, or as an Early Bird Lifetime purchase ($24.99) that removes both limits.

CastSound connects one phone to one computer at a time, so one phone acts as the speaker, microphone, and webcam together.

Yes. CastSound lets you use your smartphone as full PC peripherals. You can listen to computer audio, talk through the phone microphone, and use the phone camera as a webcam at the exact same time over a single connection.

No. CastSound is completely local and peer-to-peer. All audio, microphone, and video streams travel directly between your phone and your computer over your USB cable or local Wi-Fi. Nothing is uploaded to any remote server.
