As the fourth installment, by Filippo Bigarella, for TweakWeek, TheftAlarm takes an interesting approach to keeping your iPhone safe from thievery.

Instead of relying on a service like Find My iPhone from Apple to track down your iPhone once it’s stolen, TheftAlarm aims at making sure your iPhone never leaves the building in the first place. When your iPhone is unattached from a sync/charge USB cable, TheftAlarm will blare a warning noise that your device has been unplugged…

The concept of the tweak is very simple: If someone unplugs your iPhone when TheftAlarm is enabled, the alarm plays.

This type of feature is perfect for a setting like a coffee shop, where you may get up from the table briefly when your iPhone is connected to your laptop. TheftAlarm can assure that no one will pick up your device while you’re not looking. This tweak could be useful for someone with kids, too.

The beauty of TheftAlarm is that it’s enabled through a customizable Activator gesture. Once you have TheftAlarm installed, simply set your Activator gesture to enable and disable the tweak’s alarm mode. (The iPhone must be plugged into a USB cable for the tweak to work.)

To turn TheftAlarm off, simple perform the tweak’s pre-set Activator gesture.

My only real suggestion for this tweak would be to add some sort of visual identification that the alarm has sounded. An added “WARNING” or something of that nature would really help make the tweak’s point clear. Also, the ability to set TheftAlarm to automatically enable when plugged into a USB cable would be nice.

Overall, TheftAlarm is a great, free jailbreak tweak. To download TheftAlarm, you’ll need to have the developer’s repo:

What do you think of TheftAlarm?


  • SoCoMagNuM

    does it bypass the mute switch on the iphone?

  • AMB

    It’s very bad, the sound isn’t that loud and on top of that you can easily switch it off with the mute switch.

    Good idea, but poorly executed.

    • I’m not sure if this is what you mean, but the sound can be adjusted in the settings.

  • numbnuts

    i thought folk were just pranking around when they said it could be easily disabled with the mute switch as i thought surely the dev would’ve thought about that. how wrong i was lmao!! this is like having a car alarm that could be deactivated by simply lifting the door handle. it’s about as much use as a chocolate coffee pot – and it also keeps throwing my device into Safe Mode 😐 still needs a bit of bug solving but has some potential i guess.

    • I think the point is to shock the person and to quickly alert you. Of course it can be disabled, but no one is going to expect that noise when they unplug your iPhone (normally).

      • Let’s all be honest this is for us to catch our snooping wives/girlfriends from reading our damn texts and seeing who we called. Ten to one the dev has a snoopy ladyfriend lol!

  • north

    just steal the laptop and phone connected from the coffee shop if you’re stupid enough tto leave them both alone for any amount of time

  • Rainrose

    What’s the use of this? Only when plugged? I want an alarm that makes noise when someone else takes away your iPhone. Is there an app/tweak for that?

  • svnelvn

    you should probably turn off the iphone before you steal it anyway

  • Bob

    Can the alarm activation send a text message, e-mail or make a phone call when it is disconnected, instead of making an alarm sound?
