Count down the seconds and sound the alarm when
Set a timer and feel the seconds ticking away – even when you aren’t looking at the screen. Subtle haptic effects signify the numbers changing even when you aren’t looking at the screen. Sync the haptic effect to audio for an enhanced experience. When the timer reaches 00:00, add stronger haptic effects to this alert and sync the effects to animations and/or sounds.
