Around the Web

Oh Crap Hey app icon

Oh Crap Hey

A minimal iOS app for staying in touch. Pick the people who matter, and the app surfaces the ones you've been neglecting the longest — color-coded by urgency, with swipe-to-log, long-press to message or call, notes, snooze, a home screen widget, and Siri Shortcuts. No accounts, no cloud sync, no tracking.

Oh Crap Hey
