Why is Pokey so good? 

Pokey connects directly into your inbox relays and keeps the connection open at all times. 

Every other notification system is using a server that watches relays for new events and sends them down via Google/Apple/UnifiedPush systems.

It's WAY faster than ANY of these push systems.

There is no restriction on message sizes or frequency. No payment plans for servers and no algorithmic delays from push providers.

It can authenticate in your Private Inbox relays for DMs because it can get Amber to sign as of you. No watching server can do that.

It also decentralizes notifications from Clients. There is no need to run 15 different notification systems, one for each client you want to use. 

Once notifications are downloaded, it can pass those events to the appropriate apps to display. You can choose a default app per event kind. And if you don't have an app registered for the event, it can display the notification itself.

It's a win-win-win-win-win situation.
