Relay
My wife and I were trading nightshifts during the newborn period and kept losing track of who’d just been on, how long they’d slept, and when the next shift started. We tried Notes, a shared spreadsheet, and one of those baby-tracker apps. Nothing fit. So I built Relay during nap windows.
SwiftUI, SwiftData, no backend. Single-player v1 on my phone; a CloudKit-shared v2 for both of us is next. Submitted to the App Store in 2026.
