What is BlackBook?
BlackBook is a private personal CRM for iPhone. It keeps notes, conversations, birthdays, and follow-ups for the people in your life—work contacts, friends, and family—and its Pulse view suggests who to follow up with next. It is made by Earnestly Studios and is free to download on the App Store.
Is BlackBook free?
Yes. BlackBook is free to download. The free plan includes up to 25 people, two notes per person, and 30 days of interaction history. BlackBook Pro is an optional subscription that unlocks unlimited people, full history, and BlackBook AI. Current prices and trial offers are shown in the app.
What is the best personal CRM for iPhone?
If you want a personal CRM that is built natively for iPhone, keeps your data private, and works without creating an account, BlackBook is designed for exactly that. Tools like Dex and Mesh (formerly Clay) center on syncing contacts from sources such as LinkedIn, email, and calendars; BlackBook focuses on privacy, follow-ups, and keeping your promises to people. See our comparison of personal CRM apps.
Is BlackBook private? Where is my data stored?
Your contacts and notes stay on your iPhone and sync through your private iCloud container. BlackBook includes no advertising SDKs and your relationship data is never sold. Only the details you choose to share on your digital card or invitations leave your device for those purposes.
Does BlackBook need an account?
No. BlackBook does not require you to create an account or sign up. Open the app and start adding people. Sync uses your existing Apple iCloud.
Does BlackBook work offline?
Yes. Because your data lives on your device, you can view and add people and notes without an internet connection. iCloud sync catches up when you are back online.
How is BlackBook different from Dex or Mesh (formerly Clay)?
BlackBook is iPhone-native and privacy-first: no account, no ad SDKs, data on your device and in your iCloud, and on-device AI through Apple Intelligence. Dex and Mesh (formerly Clay) are cross-platform services—web, desktop, and mobile—that you sign up for and that sync contacts from sources like LinkedIn, email, and calendars.

How does BlackBook use AI?
BlackBook AI uses Apple Intelligence to turn your conversation notes into a recap and suggested follow-up, on your iPhone. You review before saving. It requires BlackBook Pro, iOS 26, a compatible iPhone, and Apple Intelligence enabled. Manual capture and basic extraction remain available.
What iPhone do I need?
BlackBook requires iOS 17.6 or later. BlackBook AI additionally requires iOS 26 and an Apple Intelligence–compatible iPhone.
