The Story Behind SOS111: Built by Investigators, Designed for You
As Private Investigators, our career has been spent analyzing the critical moments where safety measures fail. We’ve seen firsthand that in real-world danger, you don’t always have the time—or the safety—to make a phone call. We created SOS111 because we realized there was a dangerous gap between feeling uneasy and getting help.
We built this app to change the narrative from “what happened” to “what we can prevent.” By turning your smartphone into a discreet, dual-level alerting system, SOS111 provides a professional-grade safety layer that prioritizes speed and silence. It ensures your trusted circle of friends and family is always just one tap away, giving you an early-warning lifeline when every second counts.
Please Note: SOS111 is a friend and contact alert sharing app designed for personal safety. It is a supplement to your security plan and is not intended to replace 911 or emergency services.
