WhoIsThis is your own private caller ID, a phone-book notepad, that lives entirely on your iPhone, kept completely separate from your real Contacts. Save the people who matter with a category, notes, photos and a unique ID. When one of them calls, iOS shows Category, Name, Notes, right on the incoming-call screen — so you know who it is and why they're calling, before you answer. Never guess who "the plumber," "the recruiter," or "that seller from last week" is again. Tag them once, and the context comes to you on every call. WHAT YOU CAN DO • Keep a private phonebook, not an address book — everything stays in WhoIsThis and never touches your iPhone Contacts. • See who's calling your way — your category, name, note and ID appear on the native call screen before you pick up. • Organize by purpose — group contacts into categories like Plumbers, Recruiters or Buyers. • Add notes and photos — the call screen even flags when a contact has images to review. • Give everyone an ID — look any contact up instantly from the IDs tab. • Add an emoji to a name to make it stand out on the call screen. • Pin and unpin — choose exactly which contacts show up as caller ID. PRIVATE BY DESIGN WhoIsThis works completely offline. No account, no sign-up, and your data is never sent to the cloud or shared with other apps. Back up and restore any time from Settings — the file stays with you. GET STARTED 1. Add a category and a few contacts. 2. Open Settings > Phone > Call Blocking & Identification and turn on WhoIsThis. 3. Saved numbers now show your label when they call. WhoIsThis shows caller ID only for the numbers you save. It doesn't identify unknown or spam callers, and it never reads or uploads your phone's contacts or call history.
