Locktopus Locks Down Individual Apps on iOS Devices

If you want to share a cool game on your iOS device but not let everyone read your email, Locktopus offers a simple app-by-app lockdown solution.

Locktopus is a super simple application for jailbroken iOS devices. Install the app from the BigBoss repository through Cydia, go to the system menu and set a password–more specifically, change the default from “password” to something a little more clever–and then tap and hold any application icon on your springboard screen as though you wanted to move or delete it. When the icons begin to vibrate and the little delete X appears in the upper corner you’ll have a new addition, as seen in the screenshot here, of a small lock icon. Tap the icon to lock the app. From that point forward every time someone attempts to launch the app they’ll have to enter the password.

It’s a great app for keeping your private stuff private–email, instant messages, medical apps–and for setting up a device for a child to use. You can lock down, for example, Safari, Settings, and YouTube to keep them from getting into trouble online but keep them easily accessible for the adult users. Hit up the link below to read more about it and then visit the BigBoss repository via Cydia on your jailbroken iOS to install it. Locktopus is $2, a large sum to pay for a feature that should have been included in iOS but a small sum to pay for such a handy application.

If you’re looking for a superbly camouflaged spot to stash valuables, flash drives, or other small objects, this clever DIY fake junction box as stash spot setup is ideal.

Nearly everyone has an aversion to electricity so what better place to stash your loot than in an old (and non-functioning) junction box? In the video above Derek from Tiny Yellow House shows us how to create a fake junction box that looks so realistic only the most dedicated of meth heads will plumb its electricity arcing depths to find your buried treasure.

WolframTones Generates Ringtones via Mathematical Algorithms

For a fresh, free, and geeky source of ring tones, it’s tough to beat WolframTones, a musical mashup of Wolfram Alpha and Mathematica that generates unique ringtones based on algorithms.

Visit the site, start tinkering with the settings, and WolframTones will generate a ringtone (and several variations) for you based on the style you’ve selected. The defaults for the various styles–classic, dance, blues, etc.–are great but you can delve into additional settings for further customization. During our test, for example, we were messing around with the “signalling” category and by going into the instrumentation panel we could pick which instruments we wanted as part of our alert-style signal ringtone.

After generating a ringtone you can download it, save it (free account signup required), and/or email the results to a friend. Hit up the link below to take it for a test drive.
