BlackBook is your private dating journal: an encrypted record for the people in your life. Keep the people you're seeing, the dates you've been on, and the little things you never want to forget in one calm, beautiful place that only you can open. Everything stays on your device, encrypted. No ads. No feeds. No one else. WHY BLACKBOOK - Privacy first. Your notes, photos, and details are encrypted on your device before anything is saved. Optional sync stores only ciphertext, and its key is locked with a recovery key that only you hold. - Lock it down. Protect the app with a PIN and Face ID. An optional decoy mode opens an empty version of the app if the wrong PIN is entered, so a glance over your shoulder reveals nothing. - Calm, not cluttered. Designed to feel comfortable and capture-first, so jotting a thought takes a second. KEEP THE WHOLE STORY - Profiles for everyone you're seeing, dating, or keeping in mind, with photos, status, and the details that matter. - Date history with photos, ratings, and notes. - A private gallery with albums for your photos and videos. - A notes timeline to log every interaction. - Flags, vibes, and a "bring up next time" list so you remember what counts. STAY ON TOP OF IT - A Today view surfaces birthdays, reminders, and people worth reaching out to. - Set reminders so nothing slips. - Search across names, notes, and vibes instantly. FREE, WITH AN OPTIONAL UPGRADE BlackBook is fully usable for free on a single device, with unlimited people, notes, dates, photos, reminders, PIN and Face ID lock, and on-device encryption. SUBSCRIPTION BlackBook Pro - $4.99 per month, or $39.99 per year. (US prices. Your own currency and price are shown in the app before you buy.) What BlackBook Pro includes: - Every contact, note and photo kept in sync on all your devices. - Automatic encrypted backups of everything you have saved. - Restore it all on a new phone whenever you need to. Payment is charged to your Apple Account when you confirm. The subscription renews automatically at the same price unless you cancel at least 24 hours before the end of the period. Manage or cancel it any time in your Apple Account settings. Your life, your book. Kept private.

Verdict
The clearest difference is in-app purchases: optistore.net at none against BlackBook's 2. optistore.net also leads on iOS requirement (11.0 vs 15.0). BlackBook's advantage is update cadence (every 5 days vs every 46 months). On price, ads and device support there is nothing between them.
