When you can't ask for help, Centinela asks for you. The moment something goes wrong, the people you chose are alerted. They see where you are and hear what's happening in real time โ€” even if you can't reach your phone. YOUR VOICE IS ENOUGH A phrase only you know, or a scream, raises the alarm. No one around you needs to notice, and you don't need your hands. You decide when it's on. YOUR CIRCLE, LIVE The people you trust follow you on the map and hear what's happening while it's happening. No calls, no explaining. SILENCE IS THE ALARM Walking home or meeting someone new? Set a time. If you don't check in, your circle is told where you were going. TWO PINS One stops a false alarm. The other looks exactly like cancelling โ€” while your circle keeps following you. THEY GOT HOME Know your people arrived where they said, without texting and without sharing their location the rest of the day. NEIGHBORS NEARBY People close to you can be alerted too, with only an approximate area. The community map shows what's happening around you. PRIVACY FIRST Listening happens on your phone; nothing is recorded or sent until you ask for help. Only your circle sees your location and hears your audio. PLANS The community map is free. Protecting a circle needs a plan for that circle โ€” for 5, 10 or 20 people, monthly or yearly โ€” and everyone in it is covered. Joining someone else's circle is free. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. You can manage or cancel them in your App Store account settings. IMPORTANT Centinela is not an emergency service and does not contact the police or an ambulance for you. In an emergency, call your local emergency number.
