Habit tracker that texts you when you skip a day

I've tried every habit app and always forget to open them. I want something dead simple: I tell it what habits I'm trying to build (meditate, run, read) and roughly when I usually do them. If I haven't logged one by the end of the window, it texts me. That's it. No streaks, no gamification, no app I have to open — just a message that says 'Hey, you haven't logged your run today.' I can reply 'done' or 'skip' and it records it.
