The program 簡易防犯ブザー, developed by CheapAlgo, is an Android utility that serves as an emergency alarm system. Upon activation, the screen flashes intensely and emits a loud alarm, designed to attract attention in urgent situations. It is recommended to use headphones and keep them at a distance from the ears due to the high volume. Additionally, users are advised not to stare directly at the flashing screen to prevent discomfort.

To stop the alarm, users need to follow a specific set of steps: ① Press the menu button. ② Touch "解除" (Release) from the menu. ③ Press the menu button again. ④ Touch "停止" (Stop) from the menu to deactivate the alarm. Any other options in the menu are decoys, so if a mistake is made during the process, it's advised to start over for proper deactivation.
