KnotClock
A very customizable Countdown app for macOS and iOS that can do Daily, Weekly and Single countdowns.
Requirements
macOS 13.0+
iOS/iPadOS 16.0+
Installation guide for iOS/iPadOS
While application is ready for iOS/iPadOS (in addition to macOS), as it is not released on the App Store you will need to manually install it on your device using Xcode.
I will include a guide here later on.
