I think that would be the real winner - locks when you walk away, unlocks when you return. So simple I'm surprised it doesn't already exist.
Or that Apple hasn't built it into iOS and OS X by now.
Shave. All of you with beards. Shave. For the love of all things holy, after the BoSox - it's jumped the shark... shave. As for the app, etc. I'd like to see this grow into some multi-part thing that could optionally include voice, fingerprint, code, etc.
this page breaks my browsers back button on osx.8 chrome 30.0.1599.101. no android app?
If your page scrolls, you should have a scroll bar.
+ Really well thought-out interactions (noticing when I download, auto installing to /Applications)
+ Plain-English ToS under creative commons.
- An unsigned latest.zip for downloading, at least use a dmg so you can sign and have more control over the presentation
- Extremely difficult to find Knock on the app store. The app could open a web page or itunes, right now I'm left searching and wading through knock-knock joke apps.
- Making me run software before telling me the price of the software
All in all, you're doing great with presentation, but it has a few minuses. I can't use the software because I don't have an iPhone now, so this is where my review ends.
More apps and devices seem to be using wireless proximity as some kind of authenticator, along with the assumption that a specific received signal strength confirms the user's intent to perform some action. However, such systems seem to be quite prone to a simple attack consisting of a battery-powered bidirectional amplifier connected a pair of highly directional antennas. Simply point one antenna toward the user's p…
By the way, this attack is much more successful in reverse, for listening to and replaying keycard transactions. I was shocked to discover how little materials would be needed to make a decent amplified antenna.

Now that's a massive dealbreaker. That should be made more obvious.
Indeed. I'm thinking this is less and less secure with every word I hear about it. Here I was imagining it used overlay effects from a system process and some kind of Kerberos certificates or other mechanism to convince the computer to login for real. A fake password screen... sigh. Sounds like the next virus.
This is a gimmick, as far as I'm concerned.

You use the guest account as a honeypot so they open the Mac and use it for long enough (without wiping it) for you to get a wifi connection and can get the location with Prey :-)
Sure, that's a best-case scenario. How about no WiFi in the vicinity and a couple of accidental knocks on the phone?
Edit: although ideally Prey will still be running. They'll just be able to run amok in the meantime...!
I can't get it to work? Are there minimum requirements for the mac end? I'm using the last 17" mac they made.
