A familiar voice can be imitated. The HiSign app lets two people who have already connected check a voice conversation together. Each person speaks a fresh two-word phrase and checks the other person’s words against their screen. The phrases change every minute and come from private information exchanged when they connected. Speak your phrase and hear theirs. The family safe-word, upgraded! FOR YOUR PEOPLE Make a phrase check a shared habit with family, friends and colleagues you have already added in person. Practice together before an important call. FOR YOUR TEAM Start with one colleague and practice both sides. Agree when to check a call, including a change of plan or a sensitive request. Each contact relationship has its own phrase pair; the team does not share one group phrase. FOR IMPORTANT BUSINESS CALLS Use a mutual phrase check with established colleagues and clients who have paired in person. Your team checks, and clients can check back. CHECK TOGETHER 1. Create your HiSign card and add each other in person using QR codes or NFC. 2. On a call, open your contact's Quick Phrase screen. 3. Read the words under "You say". Compare the words they read back with the other phrase on your screen. 4. Your contact does the same. Both sides take part. EASY TO REACH, EASY TO READ - Choose compact Rows or comfortable Tiles for your Home screen. - Recognize your contacts with colored shields, names and optional aliases. - Read both sides of the phrase pair in a clear Quick Phrase view. - Keep key contacts close with Home Screen widgets. - Use password-protected encrypted backups when moving to a new phone. ON YOUR DEVICE Your stored profile and contact data are encrypted on your device. HiSign requires device-owner authentication to unlock (Face ID, Touch ID, or device passcode). There is no HiSign account or HiSign-operated identity or contact server. Contact exchanges and encrypted backup transfers happen when you initiate them. Clock-health checks and App Store purchases use network services. HiSign™ is a trademark of Insight Velocity LLC.
