I really like the functionality of the Galarm android app but I can't help but feel like it's something I should be able to self host instead or pay a monthly subscription for.
To elaborate, Galarm is an alarm app with the key feature of being able to send alarms to other people you "connect" with. For me, this means my wife can send me an alarm to do something at a certain time instead of sending me a message about what I need to do and when and then I have to go and set up the alarm myself. Also, I want to emphasize alarm here. Something that just sends notifications is basically worthless to me.
Anyone know of something I could host to get the same functionality?
I'm not sure self-hosted is what you need, perhaps just a FOSS app for your two phones?
Alternatively Home Assistant should be able to push alarms to your phones.
Home Assistant is an interesting idea. I only learned about it recently but I know it's hella dense and I feel like figuring out how to get it to do this one thing might be a huge task. I'll keep it in mind though if nothing else pops up.

This is the docs you need https://companion.home-assistant.io/docs/notifications/critical-notifications/
I might have to have a look into that, could be a great way to get the wife to do things
Hey, this is definitely getting really close. However, I think for this to work our phones would need to be connected to my Wireguard all the time, right?
If you don't expose to the internet at large, yes you would need a VPN.
I don't see contraindications about that, I have 2 Wireguard VPNs (to my VPS and to my home) on all the time and I haven't noticed any extra battery draining.
it should not as it only 'runs' when pakets are sent through it, but it also should not be much more 'expensive' than normal network pakages. that is the best part about wireguard!
