Does it work for people with ADHD who ignore notifications?

It's built for exactly this failure mode. If you have ADHD, you already know the pattern: a new reminder app works for two weeks, then the notifications become wallpaper. You see the banner and your hand swipes it before the content registers. That's not a discipline problem — it's habituation, and ADHD brains habituate to low-salience stimuli fast.

A phone call flips every property that makes notifications ignorable: it's active (rings until you decide), rare (a few calls a day at most, so the salience never wears off), social (a ringing phone is hard-wired as "someone wants me now"), and spoken (hearing "meds are in the kitchen cabinet, take them with food" sticks where four words of banner text don't).

Two honest tips from users: reserve calls for the non-negotiables (meds, appointments, leaving-the-house times) and keep ordinary notifications for low-stakes stuff — the contrast keeps calls potent. And schedule the call for the transition ("leave in 15 minutes"), not the event itself; time-blindness lives in the getting-ready gap.
