StackPatch
Read full descriptionHide full description
StackPatch helps people with crowded address books repair duplicate records without losing context. It scans contacts on the device, groups likely duplicates by matching names, phone numbers, email addresses, and close-name similarity, then gives you a clear merge preview before changes are written. Bulk cleanup is the main workflow: review grouped records, merge the useful fields into one primary contact, ignore groups that should stay separate, or move unwanted records into a local recycle bin. Deleted records are snapshotted before removal so they can be restored if a cleanup pass goes too far. The app is built for private, practical maintenance. Contacts stay on the device, and you can export the whole address book as a VCF or CSV file through the iOS share sheet to keep your own copy. Settings covers export and the retention window for recycle-bin cleanup. Highlights - Find duplicate groups by name, phone, email, and close-name similarity. - Merge useful fields while keeping a preview of the resulting contact. - Move contacts to a local recycle bin before permanent removal. - Restore individual records or the full recycle bin. - Export the current address book as VCF or CSV. - Set the retention window for automatic recycle-bin cleanup.

Verdict
The clearest difference is in-app purchases: StackPatch at none against Slate's 2. StackPatch also leads on iOS requirement (17.0 vs 26.0). Slate's advantage is device support (3 vs 1). On price and ads there is nothing between them.
