Guardian Angel watches over your computer when you can't, connecting to your phone via low-energy Bluetooth and locking your Mac whenever you leave, whether you're gone for a few seconds or a few hours, and automatically unlocking it when you return.

Not Too Close For Comfort: When you run Guardian Angel for the first time, you can choose how far you want to be from your Mac before it locks, so whether you're at home or in the office, you can tweak the range to your liking.

No Phone? No Problem: Before Guardian Angel gets to work, you'll be prompted to set a password to be used as a backup. That way, if you lose your phone, or it goes out of range, you can still get back into your Mac the old fashioned way.

No Distractions, Just A Watchful Eye: Nobody likes unnecessary distraction. That's why Guardian Angel lives in your menu bar, staying out of the way until you need it to spring into action. If you want to change any settings, the preferences button is still just a click away.

Key Features:
• Alter the range at which Guardian Angel locks your Mac
• Use Apple's screensaver as your lock screen
• Built-in actions to pause your iTunes and set your IM status to away when your Mac locks
• Add custom actions that take place when your Mac locks or unlocks.
• Support for multiple monitors

Ratings and Reviews

Works great now; line of sight does appear to affect bluetooth range


I originally bought version 1.0.4. I had a showstopper issue with the software losing connectivity with my phone (Nexus 5), which would lock me out unintentionally.
The support team worked with me right away on a beta version to fix it, and since then it’s been working great. I’m on 1.0.6 now.

One thing I’ve noticed is that the bluetooth range is indeed lessened by line of sight obstacles. The signal still gets there; it’s just that the range appears to be farther away according to the operating system. e.g. Put your hand in between your phone and the computer while on the preferences range screen, and the range indicator will lower. This isn’t a big deal, but if you set the lockout range to be too small, you’ll get locked out when you don’t want to.
The preference settings that work well for my situation:
- range slider at about 2/3 to the right,
- 10 second frequency
- 4 second double-check
- using Apple’s screensaver (with a wake lock)

Needs more work


It intermitently locks when I am at the computer with the phone on the desk. I can adjust it to the maximum distance and it still does it. For curiousity I open preferences under proximity lock and I can see my phone moving way out past the limit and then coming back……while it’s sitting on the desk. I do not recommend it until it works properly.

Not quite all it claims


I would like this to be the best of the locking aps, especially given the price, but it isn't quite all it seems. Current version will not allow you to change the screen saver, only the guardian angel screen saver. This version also does not pair with an iphone 5. Not the easiest ap to get to work.
