How can I intercept the updates/notifications from an app in Android / iOS

Question

Supposed I want to know what were the notifications provided by a particular app between time X and time Y (it could be even the simple sms app) on Android/iOS, is it possible?

Are there any specific apps that allow/do not allow us to intercept these notifications?

Answer 1

On iOS you can get access to 3rd party notifications from a second device that presents itself to the iOS device as a Bluetooth accessory. That's how Pushbullet gets notifications to the desktop.
