>2. What is the benefit of checkDaily over just calling/texting my elderly loved one? I assume that the USP is that I can easily forget about it and a machine cannot, right?

I personally have it reversed, i.e. it is the elderly (my mom in my case) that calls me in the morning.

One reason is that she needs to have her earing aids on to be able to use the telephone and it is much better when she is sitting comfortably than when (say) she is around the house or walking outside (or - as often happens - her line is busy as she is talking on the phone with someone else).

If I don't get her call by 10:30-11:00, I try calling her.

The "one touch reply SMS" idea is anyway a nice one.
