Useless

I purchased the app. Not satisfied. The idea is great. But they presented it much easier and functional. I you havent been around your Mac and it fell asleep. You have to wake up Mac, get your iPhone, open the app and the question is if you can unlock it. Even if you can unlock it, for amount of time that it gets to unlock your Mac, you can write a password on MacBook and open it much quicker. (the guy showed it, while in pocket you knock your iPhone) It never works that way. Wasted $4.99.
