ntfy iOS support is about to get much better. While I haven’t worked on the native app in a while, the progressive web app (PWA) is going to make the web app enough to receive notifications on iOS (and others).
Almost all of the credit goes to @nimbleghost for the implementation.
The background notifications will be nice! I’m using ntfy for (among other things) notifications for a housemate that isn’t as tech-savvy, so it’ll be nice to get them smart home notifications that they don’t have to keep a tab open for (if I understand this correctly).
