HiSign - The New Hello

A familiar voice can be imitated. The HiSign app gives two contacts private phrase pairs that changes every minute. The family safe-word, upgraded.

Make a phrase check a shared habit with family, friends and colleagues you have already added in person. Practice together before an important call.

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.

The phrases change every minute. If you cannot complete the check or the words do not match, pause and use your agreed way to call back.

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. Unlock with your supported biometrics or device credential.

HiSign uses the network for NTP clock-health probes and optional Google Play Billing. QR scanning uses ZXing Core locally and adds no scanner-specific network or telemetry path. Insight Velocity operates no account, contact, analytics, telemetry, crash-reporting, or remote-configuration server.

OPTIONAL SUPPORT
HiSign Supporter is an optional one-time purchase for supporter recognition and cosmetic choices. It does not change the 50-contact consumer limit, exchange capabilities, or security model.
