I took for an elderly person, for taking medication. On different days, medications are taken at different times. I needed an alarm clock that allows you to set up a lot of events. In addition, the signal must be polyphonic (an elderly person, the ear no longer picks up the usual squeaking) Has some pros: Ability to manage through the application. Flexibility of alarm settings Easy to press :) Different cons: The application must be configured in English (choose the region China and the language English)
