This remarkable app won't ever unlock the locked Mac.
It will, however, lock the unlocked Mac if you care to procure the phone, fire up the app and lock the Mac instead of just reaching for the Mac mouse, trackpad or the keyboard and locking it without all the hassle.
Even with the most liberal energy saver settings on (i.e., with the disks active and Power Nap enabled), 9 times out of 10 it won't see the Mac to unlock it.
If you're absolutely desperate for ways to squander money for something that does not do not one-tenth of what it's touted to do, you'll love this app, Mr. or Mrs. Scapegoat.
It's perfect in its sheer uselessness! Complimenti!
