Revolar is changing the way we keep those we love safe. The app works with your iPhone by prompting you to add up to 5 Revolar Contacts and connecting to your Revolar device via Bluetooth Smart. Once its set up, simply press Revolar to send an alert with your GPS location to let your contacts know you may be uncomfortable or in danger.In order to use the Revolar app you must have a Revolar Personal Safety Device and a qualifying smartphone with a cellular/data connection.With Revolar you can send two types of alerts:YELLOW: A rapid double-press of Revolar sends a yellow alert, letting your contacts know to call you and can indicate that you may be feeling unwell or uncomfortable. RED: A rapid triple-press sends a red SOS alert, letting your contacts know you may be in danger and need immediate assistance.To order Revolar or learn more, go to www.revolar.com.Continued use of GPS running in the background can dramatically decrease battery life.
