Remind Me was made by Kris, a disabled veteran living with PTSD and ADHD. Thoughts arrive at the worst moments and are gone a minute later, and by the time you’ve opened an app and typed them in, they’re already lost.
So he built an app you just talk to. Every feature was tested in everyday family life first: the missed reminders, the ones that came at a bad moment, the ones that needed saying twice. If it didn’t help on a hard day, it didn’t make it in.
