When I set the Almond to arm and exit the app, the count on the app itself shows something like 58, as if there are 58 unread notifications, but when I go into the app itself there's actually only one notification.
I am using an iPhone 6 running iOS 10.3.3 with the latest version of the Almond app.
On a side note, I don't like that the Almond app will display notifications for things I told it to do while in the app. I only expect this to happen with notifications triggered when I'm not already in the app and setting things.
