What is SafeSphere

SafeSphere is a revolutionary technology that accurately determines the distance between two or more smartphone users over time when integrated with your mobile app.

SafeSphere's proprietary technology constantly analyzes proximity data between smartphones.

How it works

A Sound Solution

  • Using precise acoustic signals, SafeSphere’s patent-pending algorithms determine how close users are to each other, alerting them to keep a safe distance.
  • The indicator is highly-customizable and works with any mobile app technology to help provide a safe environment.
  • Thanks to its unique algorithm, SafeSphere minimizes exposure in unsafe environments by monitoring short distances between people over time.
  • No other technology can accurately measure proximity for short distances like SafeSphere on mobile devices.

Use Cases

Who Benefits?

SafeSphere was designed from the ground up to help keep everyone safe: employees, customers, students, teachers, senior citizens, families, and friends.

By integrating SafeSphere’s technology, your mobile app will notify you when crowded areas become unsafe. With minimal costs and physical changes to your facilities, users can create safer movement flows during daily activities.
