I tried my Homeopathic Pill Timer app, never mind why. It works, if not perfectly, but the UI confuses the developer. And, uncertain who needs it, I’ve not pulled it from the store but have hidden it. You can still get it from here, but that’s it, for now. One problem with it is the imprecise timing of notifications, at least in WP8. There’s a window of about a minute as I recall. That was almost enough to stop me from working on it in the first place, but I wanted to get something done, a DVLUP challenge, a free phone, fame, ignominy, no fortune.
There are all kinds of timers, stopwatches, etc., in the store. I haven’t tried any of them. I thought I’d do a special purpose one, a particular use case, and see what happened, go through the process, get it into the store. I’d never done something like that before, got something out where people I didn’t know could see it, try it out, etc. Anyway, I thought it was a simple thing, in concept if not execution.
But if you want a simple, practical, beautifully simple health-care device, you can’t beat the weekly pill box. It doesn’t alert you when you need it, but its presence is reminder enough. Can’t remember if you’ve taken your blood pressure pill today? Look at the box. Is today’s slot empty? Done. Of course you have to know what day it is. But between the time you need to take something every day, and the time you can’t keep track, it fills an important function, far better than any electronic device. (I use mine mostly for vitamins.)
