On the road and receiving text messages? Too busy or just not in the mood to talk? You might just need an auto-responder.

SMS Text Responder – Convenience and Safety for any Android phone, ad-free.

SMS Text Responder has more features than the vast majority of auto-reply apps and a clean, user-friendly interface. For example:

Innate GPS Functionality – You can reply with informative messages such as: “Can’t text right now, driving past Street, City, State, Country.”

Support for the TTS Extended App by Eyes-Free Project – Have the app read your messages to you.

Create groups for customized responses

1. Inform your coworkers you’re in a meeting. (Lie!)
2. Let your guildmates know you’re driving home for the raid. (Truth!)
3. Tell your wife you’re at the gym. (Lie!)
4. Advise somebody to quit texting you because he’s annoying. (Truth!)
5. Refuse to even dignify certain people’s messages with a response.

A full list of features is available on the Android Market. If you have any questions that aren’t answered by the app description, feel free to ask. I have no financial stake in it, but I am the primary tester.
