Beach Alarm is a free Android app developed by Francesco Re that aims to help its users keep their phone safe. The app offers a loud sound alarm that goes off when the phone is moved, which can alert the user in case of theft or misplacement. In addition, the app sends notifications to the user's smartwatch when the phone is moved, so they can be alerted even if they are not near their phone.

The app is straightforward to use and has a simple interface. The loud sound alarm is effective and can be heard from a distance, which makes it a reliable tool to keep your phone secure. However, it should be noted that the app is currently limited in terms of features, with only the loud sound alarm and smartwatch notifications available. The developer has announced that GPS tracking, selfie of the thief, nearby messages, and custom sound alarm or recorder voice message features will be coming soon. Overall, Beach Alarm is a useful app for those looking for a simple and effective way to keep their phone safe.
