One library. Two phones.No accounts.
Most catalog apps assume one person. Keepers assumes a household. You and your partner both add to the same library, both see updates within seconds, both own the data equally. There is no admin user, no shared password, no per-seat fee.
How shared sync actually works
One household member creates the library. They invite their partner via an iCloud share link. After acceptance, both phones read and write to a CloudKit Shared Zone. Sync runs through Apple's infrastructure; Minner Labs operates no server in the middle.
Each item records who added it ("added by Haley") so you keep a sense of who built which part of the library, but nothing is locked to one person.
No accounts, ever
Keepers does not have a sign-up flow. There is no Keepers account, no Keepers password, no Keepers email verification. iCloud is the only identity. If you can sign into iCloud on your iPhone, you can use Keepers, and your partner can join your household with one tap on a share invite.
Use cases we built it for
- Walking through a thrift store and wanting to know if you already own a book.
- Cataloging a Blu-ray collection that's grown across two partners' previous lives.
- Adding a stack of holiday-gift books on one phone while the partner is out of town.
- Keeping a calm record of editions and where each item came from.
