Compatible with iOS 5.x and 6.x
Check for new notifications without pulling your phone out of your pocket. Use an Activator gesture (like holding a volume button) and your phone will vibrate if you have notifications waiting on your lockscreen. You can discreetly check for new messages without being "that guy" who is always yanking his phone out of his pocket.
The vibration works even if you have disabled "Vibrate on Ring/Silent" in Preferences.
Configure action from Activator Settings.
To start using PocketNotify, to go your Activator preferences, and select a gesture. It makes the most sense to pick a lockscreen-only gesture that involves a physical button, so you can easily activate from your pocket.
