Hamilton CapTel Apps
Hamilton CapTel for Smartphones allows you to read captions of what's being said to you during phone conversations as you listen and talk with people on the go! Similar to captions on a television, word-for-word transcriptions of what's said are displayed on your smartphone.
Talk with anyone on the phone anywhere, anytime, and see what they say. Place and receive calls on your mobile device, and read captions of what's being said. You'll never miss a word again!
