Good security often consists of multiple layers. This app attempts to help secure your phone at a physical level. If a potential thief tries to take your phone, then they will be greeted with a loud alarm of your choosing. Usually a blaring alarm is enough of a deterrent to prevent theft in a public or private setting.

Use Cases
• Leaving phone on the sideline when playing pickup basketball
• Setting phone down when working out at the gym
• Placing phone in your pocket walking through crowded areas
• Setting phone in your purse when walking around the grocery store
• Leaving phone on the side when riding a roller coaster
• Putting phone in a bag on the ground while watching a show
• Leaving phone on your desk at work when you use the bathroom
• Charging your device in the airport
• Pranking someone you know with a personalized audio clip when they take your device
