I'm building a simple app to let friends and loved ones know how you're doing. I know many people in some of the current troubled regions of the world, and whenever a particular event happens it's really nerve-wracking for those of us not there, wondering if our loved ones are okay.

WhatsApp and messenger groups don't work for this kind of thing because 1) people are often members of many different groups that they would have to constantly notify if they were "okay" during a particular event and 2) many troubles in the world are ongoing, and constantly spamming a message group saying "I'm still okay" doesn't work.

My app just lets people hit a single button to tell any interested friends / family that they are safe. They can do this as many times as they like.

Normally I would be worried about premature optimization, what I've been spending extra time making the tech stack initially very performant. It's working for my family but once I deploy to the world I want it to be solid and stable, or it loses a lot of its value.
