User Reviews

  • I'm using OS X 10.11.4. 1. When I try to arm the alarm, the alarm immediately alert. 2. When I close lid, the alarm disarm but arm whenever I open the lid back. 3. The password can key in again if I key in wrongly by hitting the backspace then key in the correct password. 4. If I quit and enter the app again, it won't sound when I arm but still will sound after few seconds even though nobody is touching the laptop.

  • It works. It supports pretty much everything you can think of. It doesn't crash in the hands of a casual user. It supports almost any application yoou need! Really usefull
