New Medical alert app, for stroke victims

So about a year ago, my Dad had a stroke. It was fairly minor, but the doctor stressed that the first 3 months were the most crucial time to be alert about a potential follow-up stroke...

... it made me nervous, and I tried to ensure (as Dad made his prayerful recovery) that I could keep tabs on him. I asked the doctor about medical alert devices, but he said they generally weren't covered insurance-wise here in the US.

So I started making an open source medical alert app, specifically with stroke victims in mind:

Basically, it sends a text message to the "caregiver" if the "caregivee" doesn't respond within a designated time. This is in contrast to traditional medical alert devices, that require a caregivee to press a button. As we all know, someone who is experiencing a stroke can have temporarily limited mobility and cognitive function, so pressing a button can be out of the question. This app would instead automatically be able to "text" for help if they don't check in at the expected time. The check-in time can be adjusted too... to try and ensure critical minutes aren't lost, but also while trying to balance the independence of the caregivee.

It took a year or so to make, well past the time that Dad had fully recovered.

I'll grant you, it's not for EVERY stroke victim. Folks recovering from very massive strokes where they wouldn't be able to check in at all — even if they were fine — probably can't use it. And folks who are recovering much more rapidly from minor strokes and don't need a caregiver to be with them so often also probably wouldn't need/want it either...

... this is really for the wide spectrum of folks in the middle, and specifically only designed to be used for a few hours at a time (to give the caregiver time to run errands and the caregivee a bit more independence).

The app is open source, free, no ads, not even a donation button, to make it as accessible as possible to medicare/medicaid patients, since these programs don't generally cover medical alert devices. The advantage here is that because it sends a "text message" instead of relying on a remote web server, that means no server maintenance costs and (therefore) it can be completely free without ads or even a donate button (intrepid programmers could even try their hand at improving the open source code.) The disadvantage is that it means a lot of app publishing stores with strict regulations on text-sending apps probably won't post it, and also any potential updates to the app need to be "checked for" manually since it's so self-contained.

So I'm currently self-publishing it on Archive and Github.

It's available to sideload on a variety of Android versions (note: "sideload" just means to manually download an app and install it). I tried to make this app as compatible with as many versions of Android as possible, and theoretically would be able to work on Android phones as far back as 2014, so long as they are still capable of sending "texts".

I was hoping I might be able to convince some of you to help me test this app. Or if some of you have programming experience, maybe you could help develop or branch it into alternate versions. I've provided more information over on this subreddit (like an FAQ and download link). I'm using a subreddit because it's a free alternative to me having my own website so I can ensure the app remains accessible: r/Caregivee (http://www.reddit.com/r/Caregivee).

(P.S. By the way, yes I did make the animation. Animation is a greater interest of mine than programming, though I have an interest in both).
