The ability to schedule messages is made possible on my iPhone thanks to the wonderful BiteSMS app, but since I'll be making the transition from iOS to Android this week having picked up the HTC One, I just had to go out and find an Android app offering this vitally important functionality. I perhaps got more than I bargained for in my discovery of Schemes, an app which not only facilitates the sending of SMS messages at predisposed times, but also emails, Facebook updates and Tweets.
