Sprint announced today that it will now be offering its Wireless CapTel service to iOS device users, enabling the hearing impaired to read “real-time word-for-word captions” of conversations on their iPhone, iPod, or iPad.

Wireless CapTel by Sprint users place a call in the same way they would when using a traditional phone – by dialing the number directly on the device. The revolutionary application then connects callers directly to the CapTel service when the phone is dialed. When the receiving party answers, callers can listen to what the other person is saying and also read captions on the phone’s display screen.

Incoming calls will be routed through the service as well for users with a CapTel by Sprint number, allowing customers to receive the real-time captions for every conversation. Previously, the service was only available on select Android devices, including the LG Optimus G, HTC Evo 4G, and Samsung Galaxy SIII, and a few others.

Sprint is making the functionality available through a free app available on the App Store, and the service available for free to users on an Everything Data plan.

You can get a look at how the service works in the video below:
