Your address book is full of duplicates, names you no longer remember, and entries with half a phone number. Cleanbook turns cleanup into a quick swipe session — keep what matters, drop the rest. WHAT IT DOES • Sweep sessions: swipe right to keep, swipe left to delete. Haptic feedback, undo, and a progress ring keep you in the flow. • Smart home categories: Duplicates, Ghosts, No phone, Rare contacts, Approved (your keep-list), and All contacts. • Side-by-side duplicate compare with field-level merge — pick the right name, the better company, the cleaner phone, the email worth keeping. • Trash with a 30-day safety net: every deletion is reversible. Restore a contact and it comes back exactly as it was, including notes and organization. KEY FEATURES • On-device duplicate matching by phone, email, and name. • vCard archive in trash so a restored contact is byte-identical to the original. • Approved list: contacts you decide to keep are remembered, so the same records are never shown again in a future session. • Native iOS 26 design: Liquid Glass tab bar, full Dynamic Type support, light and dark modes. PRIVACY-FIRST • Cleanbook never leaves your device. No accounts, no analytics, no third-party SDKs, no network calls. • The only permission asked is access to your contacts. It is required for the app to read, compare, and update them — nothing else. CLEANBOOK PRO Cleanbook is free to download. A one-time Cleanbook Pro purchase unlocks unlimited swipes per session, duplicate merging, the Ghosts category, and an unlimited Approved list. No subscription. Restores across devices via Apple ID. WHY USE IT The native Contacts app shows you the list. Cleanbook gets you to the empty-inbox version of it: a clean, current address book you can actually trust.
