zeroc

Triage your address book.

Free · Designed for iPhone. Not verified for macOS.

Pull up your address book and decide on each contact, one card at a time. Keep, edit, or delete — nothing leaves your phone unless you tell it to. zeroc is a tiny tool for triaging the contacts already on your iPhone. It shows you one contact at a time, oldest-edited first. For each card you choose: Keep (set it aside, never see it again), Edit (open it in the system Contacts editor and save changes), or Delete (remove it from the source of truth — iCloud, Google, Exchange, wherever it came from). That's the whole app. No accounts to sign in to. No cloud sync. No ads. No tracking. No data ever leaves your device — we don't run a server. The contact you see on screen is read directly from your iPhone's unified address book using Apple's Contacts framework, and any change you make routes back through whichever sync layer owns that contact. The Apple Watch companion shows the current contact card on your wrist and lets you Keep or Delete with a tap; the iPhone holds permission and does the work, the Watch is just a remote. zeroc is part of the zero suite — small focused apps that strip everything away except the one thing that matters.
