Push-Notification services for iOS: Bypassing the APN Keys and Apple Store fees using a service offering an iOS app

Question

I have been using pushbullet for months but something happened a week ago and I cannot get to send my pushes. Support has been horrendous.

So I decided to look for an alternative.

I ended up using Pusher which seems fairly promising and support is prompt.

Unfortunately, they don't seem to have an official application and, instead, aim towards a "build you own application to interact with your back-end server"

Which is great! Especially for Android, as APKs can be installed with no certificates without too much hassle.

iOS on the other end is tied to a $100+ fee to enroll as an Apple Dev and publish apps in their store.

Question: Is there a reliable and easy push-notification service/software that I can install on my backend to be able to push a highly reliable and fast notification on my iOS device(s) via AN EXISTING APP (not MY app ... an existing official app, like pushbullet!).

Answer 1

Pushbullet was apparently having issues as everything came back.

It took a long time and was not advertised.
