KK Number Helper

KK Number Helper is an iPhone-focused utility that enhances how you handle calls. It enables a customizable Caller Show with backgrounds from local photos, camera captures, or online galleries, and it supports quick sharing of backgrounds with loved ones.

It also helps clean and safeguard your contacts by batch-adding the +86 country code, flagging and updating harassment numbers, enabling fast number lookup, offering access to common numbers, and merging duplicate contacts for a tidier address book. A VIP subscription with monthly plans is available, along with clear Terms and Privacy Policy.
