Mutuals lives inside iMessage. Add it to any conversation and instantly see every contact you both share.
Download Mutuals and sync your address book once. We store only phone numbers — no names, photos, or other contact details.
Open any conversation, tap the Mutuals icon in the app drawer, and send a connection request.
Once the other person accepts, you both instantly see every contact you have in common — and nothing else.
We store phone numbers, not names or message content. Your full contact list is never shared with the other person — only the overlap is revealed to both of you.
We only work if you sync your full address book — selective sync breaks mutual matching for everyone. Read our privacy policy to see exactly what we store.
