This is a simple app to set an alarm based on any movement of your phone. This can potentially be used to alert you in case you suspect if someone can spy or access your phone behind you.
It gives you 5 seconds once you tap the activation button to lock and keep your phone steady. You have the option to cancel it while its activating. Once activated it can only be cancelled if the phone is unlocked.
A sensitivity slider is provided to adjust trigger threshold for motion alarm. A low setting makes the trigger harder and you can assume only considerable amount of sudden phone movements would potentially trigger an alarm. While on the other hand, the highest setting should be able to trigger the alarm even on slightest movement of the phone. Again this setting should be dependent on your phone's hardware features and consequently the resulted sensitivity of alarm trigger should be adjusted accordingly.
App uses Android's Alarm audio stream to play back the siren sound, it doesn't matter if this audio stream is muted, audio will still be played once triggered at full volume even if you've earphones plugged.
Please note below points before using the app:
