I'm looking for a native iPhone app which will cause a phone to continue vibrating when a text message comes in from a specific number until a cancel button is clicked. This number will need to be entered into a configuration screen.
For example. I choose the phone number 555-555-5555. Every time I receive a text from 555-555-5555 it will vibrate and pop the text message on screen. It will continue to vibrate until I click a cancel vibration button.
It will need to run in the background all the time.
Will need an android app in the future as well.
