Contact Cleaner for iPhone
Three entries for the same friend, numbers without names, contacts missing half their details. Cleana finds duplicate and incomplete contacts, merges them safely, and keeps a backup so nothing is ever lost.
- Finds and merges duplicate contacts in one pass
- Flags incomplete entries: missing names, numbers, or emails
- Backup and restore built in, so cleanup is always reversible
How the contact cleaner works
- 1. Back up: Cleana snapshots your address book first, so you can restore everything with one tap.
- 2. Scan: duplicates and incomplete entries are detected and grouped on-device.
- 3. Review: see exactly which entries will be merged and what the final contact will look like.
- 4. Merge: confirm, and your address book comes out clean and organized.
How contact chaos happens
Every synced account adds its own copy: iCloud, Gmail, Exchange, WhatsApp. Switch phones a few times, import from a SIM card once, and suddenly the same person exists three times with different subsets of their information. Deleting the wrong one risks losing a number you need.
Cleana merges instead of deleting: matching entries are combined into one complete contact, and the built-in backup means even a wrong merge is reversible.
Private by design, like everything in Cleana
Your address book is some of the most sensitive data on your phone. Cleana processes contacts entirely on-device: nothing is uploaded, and the app works with no internet connection at all. Read more about how Cleana works 100% offline.
While you are tidying up, the duplicate photo cleaner gives your photo library the same treatment.
Frequently Asked Questions
How do I merge duplicate contacts on iPhone?
Open Cleana, go to the contacts section, and run a scan. Duplicates are grouped together with a preview of the merged result. Confirm and the copies are combined into one complete entry.
Can I undo a merge if something goes wrong?
Yes. Cleana backs up your address book before cleanup, and you can restore it at any time. No merge is ever permanent.
Does Cleana upload my contacts anywhere?
No. Contact scanning, merging, and backups all happen on your iPhone. Your address book never leaves your device.
What counts as an incomplete contact?
Entries missing key details, like a number without a name or a name without any contact method. Cleana collects them in one list so you can fix or remove them quickly.
