iOS: Sometimes, you need to make a note that's easily accessible from anywhere. NoteDash gives you just that. Type out a note, and it shows up in Notification Center.
NoteDash isn't a replacement for your usual notes app. It only has one purpose: make text easily accessible in the Notification Center. So, you only get one note in NoteDash, and whatever you type there is what shows up in the Notification Center. It seems a bit too simple, but it's actually very useful for one-off reminders, such as reservation numbers and carpark numbers.
