Problem & Solution
In crowded subways, coffee shops, or busy office spaces, using your iPhone often leaves your personal messages, banking apps, and confidential notifications exposed to unwanted eyes. Constantly checking who is looking over your shoulder ruins the experience of using your device in public.
