Did a search and didn't see anything on this.

I ride a bike and having the autoresponder is great to let folks know that I'm unavailable while riding.

The dev (GSquared) updated it for iOS6, but has yet to even respond to any of my emails about an update for iOS7. I even offered to pay for the upgrade after paying for both the pre iOS6 and again for the iOS6 updates.

Any suggestions or does anyone have any insight into this dev's activities?

Or can anyone else write the same for $?
