I tested lots of Clock apps for their ability to alarm on a fresh reboot without even entering a SIM pin.
This is required to have auto-reboot and reboot after system update to work, without oversleeping ;D
Working
preinstalled AOSP clock
Works reliably but no support for hardware buttons or shake. Also looks pretty... blue.
new clock
Support for hardware buttons, shake and flip. Apart from that a fork of the AOSP clock. More modern design but not much more recently updated.
Has a minor glitch where the alarm screen doesn't cover the whole screen of a Pixel 6a, works normally though.
