Jolt: Prank & Alarm

Jolt: Prank & Alarm


Prank or scare anyone who tries to move your mobile device. Get alarmed when somebody messes with your phone.
Jolt uses the accelerometer of your phone to detect motion and plays an alarm or funny sound instantly or after a sort delay.

★ Features ★
✓ 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
✓ Detect motion even when device is in stand-by mode (*)
✓ ...

(*) Exclude jolt from task killers. A few phones may not work in sleep mode due to a known android bug.

★ Ideas ★
1. Sneakily activate Jolt in your friends' phones , choose scream sound and watch their reaction when they pick it up.
2. Activate Jolt on your phone with an alarm sound and password protect your lock screen. You will know for sure when someone tries to take it
3. Activate Jolt with a delay and a fart sound. Ask someone to bring it back to you. He will get sooo embarassed!
4. Activate Jolt without delay and annoy everybody by simply shaking your phone
5. Post your idea in the comments area

@Jason: Password protection is not going to be be implemented as it will only give you an illusion of safety. Anyone could just turn off the volume or shutdown your phone. The best solution is to password protect your lock screen.

@Armando, @dionisus, @jasand: There is a combination of hardware - android version, that on a few devices turns off accelerometer when the screen goes off. Please check latest version >1.4.0.

Great app I looked and looked passing this app many times not thinking this is the exact app im looking for, this app just is just too sensitive. A setting to zero is the same sensitivity as ten, and if you could have up to 3 hour delay, you would definitely get my 5.
