Buckman, sorry to here of your loss. I am afraid that texting has become a substitute for a conversation but I have never understood why. If it is urgent I would try the phone first and the text can be useful as a back up if you get no reply.
Totally agree that many apps now coming out on things seem to be more because they can, rather than because they are of any use. Why you need one for a power washer when you have to be holding it to work it is completely beyond me as are those for fridges and the like.
