Jolt is a small and simple ad-supported application that can be used either
  1. for making practical jokes to your friends or
  2. getting you alarmed when somebody messes with your phone
Jolt uses the accelerometer of your phone to detect motion and plays an alarm , a funny sound or a custom sound instantly or after a sort delay

- see attachments -

✓ Many sounds to choose from (siren, car alarm, scream, farts, burp and more)
✓ Choose any sound from sd card (requires a 3rd party file manager like ASTRO, OI File Manager, ES File Explorer etc)
✓ Adjust the sensitivity of the motion detector
✓ Choose the delay between movement and sound
✓ Vibrating during playback
✓ It can detect motion even when device is in stand-by mode
✓ Option to pause during incoming calls
(Sorry but I am not allowed to post direct links)
Feel free to report any bugs or requests here.

Fixed: Leaked IntentReceiver (thanks to MobileWon)
Trick g-sensor stay on, when screen goes off (Most phones do not need this. Some phones require this in order to work in sleep mode. Unfortunately a few devices will still not work in sleep mode due to a known android bug)
Added: Customizable activation delay
Added: Activation Countdown
Added: Option to pause alarm during incoming calls
Fixed: Bug trying to activate even if no accelerometer is present
Changed: Detect motion in sleep mode is always on
Changed: Remove option Detect motion in sleep mode
Fixed: Minor UI corrections
Added: Choose custom sounds from sd
Fixed: FC media player not initialized
Fixed: Typos on share subject and body
Fixed (hopefully): Rare FC on playback
Removed "lite" from title
Added: Share Menu option (use it to recommend this app to your friends)
Added: The program remembers last settings used
Fixed Bug: "Detect motion in sleep mode" working only after unchecking and rechecking it.
Add vibrate option
Optimize some sounds (amplify, smaller size etc)
Deactivate also stops playing sound
Remove "Play sound once" option
Default sensitivity set to 50
Fixed Bug:When the program activated with "play once" unchecked and*a delay could sometimes put sound in queue even if it is already scheduled
Fixed Bug: FC due to renamed sound (puplfiction -> robbery)

Hello all,

I am trying to figure out 3 comments in market stating that Jolt is not working in sleep mode. So if anyone wants to help please just post here or pm me your device, rom and whether jolt is working or not in sleep / standby mode. If it is not working a logcat copy would be very helpful.

So far I have tested it and it is working for sure on the following devices:
Desire (stock rom, oxygen, devnul), Desire S, Wildfire, SE x10 Mini, Galaxy Tab

Three comments in market suggest that it might not work in sleep mode on:
Evo 4G (CM7), Atrix 4G and ZTE Blade.


PS. Version 1.3.5 is coming soon with new feature of choosing arming delay.

Thumbs up New Version is out:
I have just uploaded a new version to the market:

The main new features are:
  • New option to pause alarm during incoming calls
  • Option to work in sleep mode removed as this now always on
  • New slider to select activation delay
  • Better support for some devices that had problem working in sleep mode
  • Added a simple activation countdown

Most phones should now work in sleep / standby mode. Unfortunetely a few will still turn off accelerometer when the screen goes off. Please report to me your device and android verion if you have such a phone.

Thanks for your support,
