Use subtle haptic effects to signal the passage of time.
Feel every second, minute or hour. Know when you’re running out to time.
Through subtle haptic effects, you can make your phone feel like the back of your watch or the grandfather clock in the hall, but silently. Use subtle haptic effects to count down the seconds and sound the alarm when time is up.
Each haptic signal can 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.
