I struggle with time blindness and kept missing client Zoom calls. MacOS notification banners appear for 5 seconds and vanish...my brain can't hold onto them. I spent 2 months building a solution.

What it is: Chime shows full-screen alerts that physically interrupt whatever you're doing. It's impossible to miss.

Technical details: - Built entirely in Swift/SwiftUI using Cursor. - Uses EventKit for Calendar + Reminders integration - Todoist REST API v2 for task sync - All data stays local—no cloud sync

How it works: - Syncs from Calendar, Apple Reminders, and Todoist every 1-30 min (This is customisable) - Extracts meeting links from meetings (30+ platforms: Zoom, Teams, Meet, Webex, etc.) - Schedules Timer-based full screen alerts with customizable timing - Sound rotation system to prevent habituation

The insight: Most accessibility focuses on making things "clearer" or "simpler." Neurodivergent brains need "impossible to ignore." Subtle equals invisible. I've been using it for a few weeks and went from missing chunk of meetings to zero.

Try it: 14-day free trial on Mac App Store. No signup required, just download and grant Calendar permissions. https://apps.apple.com/us/app/chime-remember-everything/id67...

Happy to discuss: - Building macOS apps with AI assistance - EventKit's quirks (hourly recurrence workaround, full screen alert implementation, etc) - Designing for neurodivergent users
