The Television app in the Android Market is branded by BluMediaLab, and I don't know if they have any affiliation with the creators of the iPhone version - makayama.com. Both versions are $2.99.
Apple restricted the iPhone version to Wi-Fi operation alone. The Android app seems to work a bit on 3G, but even Wi-Fi gave me sketchy access. The major stations worked great, but the lesser-known channels were unreliable.
