The app pushes a notification to your phone the moment something restocks at a shop you follow. It is the same subscription as your Discord roles, so what you pick in one shows up in the other. You need an active membership.
Pick your device below.
Install first, then link. iOS only allows notifications from an app on your Home Screen, so turning them on inside Safari will not work.
Needs iOS 16.4 or later. The code is typed rather than handed back automatically because Safari and the installed app do not share a sign-in, which is also why step 4 has to happen before step 5.
Every notification shows the Pokénnoisseur icon rather than the shop logo. iOS does not let a web app change it. The shop name is the first thing in the notification text.
To get a Home Screen icon, tap Install app when that button appears, or open the browser ⋮ menu and choose Install app or Add to Home screen.
On Android the alerts work from a browser tab as well, so installing is optional. It keeps the app out of your tab list, which is the main reason to do it.
Chrome, Edge and Brave all work. Firefox and Safari on a Mac are not supported.
To install it as its own window, use the install icon in the address bar, or open the browser menu and look for Install.
On a Mac, also allow notifications for the browser itself in System Settings, Notifications. If that is off, the app will say alerts are on and nothing will ever appear.
On Windows, check Settings, System, Notifications, and turn off Focus assist or Do not disturb.
Work down this list. The first two cover almost every case.
Still stuck: post in Discord with your device and what the app says on screen.
