How Are You?!

My wife's grandfather had cancer and was in bad health. Her mother was his caregiver — sleeping next to him every night, constantly afraid she wouldn't notice in time if something happened. My wife said: there should be an app that watches quietly and alerts the family when something seems wrong. And I know about a lot of such cases, where old people live alone, and their children are constantly worrying about, if they are OK. I looked at existing solutions. Medical alert pendants need a button press — useless if someone is unconscious. Life360 tracks location but doesn't understand routine. Subscription services charge $30-50/month. Many of those solutions are annoying and intrusive for our parents. Sometimes they feel spied, that we don't trust them. Sometimes they want to feel and be treated as young human beings. I thought about it for a long time. It was not easy to think for algorithm that traces daily behavior. Static algorithms are just too stiff, and can become really complex. Complexity means error-prone code, false positive alerts, it means difficult support and a lot of different problems from the same aspect. Modern technologies came the last few months, so I built it. 125+ versions, ~126,000 lines of Kotlin. Actually, what I discovered with this journey is that the hardest part wasn't the algorithm — it was keeping the app alive. Samsung, Xiaomi, Honor, and OPPO aggressively kill background apps. I built an 11-layer service recovery system to survive every battery killer I could find, while keeping battery impact under 1% per day. How it works: - Install on your parent's Android phone - 7 days of learning their routine (wake times, movement, locations) - Then 24/7 monitoring — if something deviates, your family gets an email with GPS coordinates and recommended actions No wearable. No button. No check-ins. The app follows the 'install and forget' principle. It is there, but it is implemented in such way that it doesn't bother with its existence. Yes, the parents can open it and see interesting statistics, but this is optional. We don't want anything from them. Just be safe and happy. :) Emails are sent to a list of participants, in case of detected alert, and weekly, to show the applied behavioral adjustments. Free 21-day trial, then $49 first year, $5/year after. Why so affordable? It must be affordable, so that many people in need can use it. The amount is needed to cover the expenses for support, and nothing else. I don't expect to become rich out of this
