Countersign: Family Safe Word

Scammers can copy your son's voice on the phone. They can't copy the word only your family knows. Countersign is a scam-check app for families. It helps older adults work out whether the person calling them is really who they say they are, and gives their adult children a way to help without being on the call. THE CALL COMES AT 11PM Cloning a voice takes about three seconds of audio. People pull it off a video, a voicemail, a social media post. It's your grandson's voice, crying, telling you he's in jail and asking you not to tell his mother. It isn't him. But it is his voice. There is no app that can reliably tell you a voice is cloned while you're on the phone with it. So Countersign doesn't try. It helps you do the thing that actually works. WHAT IT DOES Set a family safe word. One word your real family knows and nobody else does. Someone can clone a voice, but they can't know a word that was never written down anywhere. Verify a caller. One tap shows your word in the largest type in the app. Ask them to say it. Get told what to do. If they can't say it, four screens walk you through it. One instruction at a time. Hang up. Don't use the number they gave you. Ring the one already in your phone. Tell someone. Tell your family. One tap sends a message to the people you chose ahead of time. How to stay safe. Practical advice that needs no app at all, including how to stop unknown numbers ringing your phone in the first place. Free, always. WHAT COUNTERSIGN WILL NEVER DO It will never tell you whether something was made by AI. Detectors are unreliable, and an app that tells you something is probably fine when it isn't could cost someone their savings. The safe word works for the opposite reason: it's information that only exists between people who trust each other, and it was never online for anything to learn from. YOUR SAFE WORD STAYS ON YOUR PHONE It's stored in your device's Keychain. It is never sent to us, never included in a notification, and never copied to another device or backup. There is no account and no sign-in. We never ask for access to your contacts. When you choose someone to alert, iOS shows its own picker and passes us only the person you selected. FREE, AND ALWAYS FREE Setting a safe word. Verifying a caller. The whole guided flow. One trusted contact. Practice reminders. How to stay safe. Nobody is ever asked to pay while a scam call is happening. COUNTERSIGN PRO Up to five trusted contacts, so a whole family gets told at once.
