Use Cases

  • Tom has family and friends in Asia and keeps in touch with them every few months - he loves using the Alarm app to help him keep track of time zone differences so he make sure to call them at a appropriate time of the day
  • Tom no longer owns an alarm clock and solely relies on his mobile phone as an alarm clock to wake himself up each day
  • Tom has a diverse schedule and needs to set different alarm times throughout the weekdays and weekends. He is able to customize the alarms with different labels and sounds.
  • Tom likes to sleep in, especially on the weekends, and uses the snooze button so he can see how his dream ends.
  • Because Tom loves to cook, he finds it very convenient that his phone offers him the ability to use the timer feature in the Alarm app so he doesn't overcook his meals
