Just works. It also has some nice features compared to other clocks.

Second. Great clock, supports direct boot so you can auto-reboot at night and still wake up
Looks like this is the one 👍
Other users are saying other apps have issues. Hopefully this one is good.
I would use the default one butI de-googled and removed all their apps. Next step is to install graphine/e-os (not both are supports for my phone) one day.
Use that one tꝏ ! Only issue is dœsn't wake screen up from locking wen alarm gœs off so hafta turn screen on → unlock phone → enter notification panel → stop alarm from there
I just use the stock clock app on GrapheneOS 😕. Its not pretty, but it works. The two below both look pretty good, maybe its time for me to reevaluate what I'm using.
I had issues with chrono on graphene, I wanted it to work so bad, but it kept getting stuck on start splash screen and even when you close, force close, clear cache, clear data, and reboot phone, it wouldn't work only after deleting and reinstalling. Also alarms were being 5-20 minutes late, often, depsite doing everything to keep app alive.
I use fossify clock currently, haven't had an issue.
I like Chrono. Current version does seem kinda buggy, though.
No idea why GrapheneOS doesnt use the very nice and modern LineageOS apps. They are just AOSP with minimal additions.
Maybe it is some stupid license incompatibility as they want to keep the option to lock the OS down or something...
Using stock LineageOS apps on other systems doesnt work as they have wrong IDs and might have permission issues
That seems like a possibility. Yeah, LineageOS has some great stock apps, I wish they were more possible outside the OS itself.
Someone can softfork them, change the App IDs to org.lineageos.x and release apks.
I started doing that a while back, but Android dev is complicated.
Need to test more, but Chronos from F-Droid seemed interesting from what I already tested. Plus it has redundant means of not having its process killed by the system, as some do when running out of RAM for example.
I just use the native app of the lineageos.
I'm still using Timely, although you have to edit it's AndroidManifest to add the necessary permissions for newer Android versions. One more thing that was bought and killed by Google.
Alarm Klock.
I'm trying to switch because I can't change the alarm timeout(not snooze).
Klock is the smoothest I've found so far though.
I suspect this is a problem of fragmentation on Android. I've had issues when I tried other Clock apps than the Google one. Alarms would not be triggered for various inexplicable reasons. Or they reset if the launcher crashed for whatever reason. I don't have the time and energy to test this simple function that I rely on quite heavily. And that's why I stick with the stock Google app because it has never failed me personally no matter whose manufacturer's version of Android it ran on.
I detest alarm clocks. I wake up when my body needs me to.
My bank account needs me up before my body. Then I take coffe. Then sleeping pills ti get to sleep, and booze on the weekend to forget it all.
The change and small time leftover is a blast though.
Although I use it for timers too like "pickup family from thing", "turn off sprinkler" etc.
