Idyno: Caller ID & Numberbook

Idyno helps you identify unknown callers, see spam and fraud warnings while your phone rings, and block nuisance numbers. Look up numbers in seconds, including directly from another app’s share sheet. Caller names are shown to subscribers.

The app can clean up duplicate or incomplete contacts, back them up for restoration on another phone, and help you create a personal contact card to share by link, QR code, or NFC. Idyno has no ads. A free first-month trial is followed by an automatically renewing yearly subscription; cancellation is available at any time.
