I can be laying in bed at 2:00 in the morning and remember I need to ask someone a question or tell them something. I can open Auto SMS and compose the text, then set a date and time for it to send.
Funny thing is, it has a Birthday area too. You can open up the Birthday tab and put in everyone's birthday and a custom comment for every one of them. You can set when it is sent so you friends who work night shift don't get a wake up text on their birthday. My memory isn't as good as it once was, but still better than Biden's. Many times I will be sitting somewhere and I get a text from a long lost friend or family member saying "Thank You". I open up my texting app and find I had sent them a birthday wish, I then open it back up and reply "you are welcome, I hope it is a good birthday". Funny thing is if I die, nothing to stop it from continuing to send these other than the battery dying. I can imagine their reaction if I get hit by a bus then send them a birthday wish a few months later.
