Build a daily check-in app that alerts my emergency contacts if I stop responding

I live alone. Work from home. Last winter I slipped in the shower and couldn't get up for like 20 minutes. I was fine but just lying there on the floor thinking — if this was worse, nobody would find me for days. My mom calls me every morning now but she shouldn't have to. I just want the simplest possible thing: one button. I press it every morning. If I don't press it by 10am, my mom gets a text. That's it. That's the whole app. I looked and nothing like this exists that isn't bloated with features I don't need.
