Your iPhone probably lights up with push notifications all day long, but only a small fraction of those are likely to be important. Unfortunately, there’s no easy way to discern between important and non-important notifications without looking at your display, and this means that if you’re smack in the middle of something important and can’t look at your handset, you won’t know what you’re missing.
The aforementioned situation doesn’t come up too often, but it may happen more frequently when you’re at work and stuck in meetings all day or when you’re in class and don’t want to make it obvious that you’re checking your iPhone for notifications. For that reason, a newly released and free jailbreak tweak called NotiVibe by iOS developer AnthPak may come in clutch.
