it's just a game. yes, it's a CRM for the people you're seeing. incredible. also genuinely useful. —————————————— THE ROSTER everyone you're talking to, on one screen. each person gets a number, worked out from your own logs and ratings. it's not advice. it's just a game. THE LOG talked, hung out, a moment. a few taps, and it prints you a receipt. keep it for your records. obviously. THE FILE a file on everyone: the story so far, your notes, the quick ones. log a note and the facts land on their file. THE KIT tools that do the chores. draft a text, turn a screenshot into a log, find "the one with the boat," or catch up on someone before you see them: one paragraph, from your own logs. it types, reads and remembers. no takes. TONIGHT pick a vibe. see who's on file for it, by your own ratings. THE WEB + THE MAP who knows who, and where. in case that comes up. THE LINEUP share your roster with every name blacked out. receipts, wrapped and badges share the same way. —————————————— PRIVATE BY DEFAULT. PIN lock if you want it. no feed, no other users, nothing shared. nobody else ever sees this. that's the whole point. delete everything anytime. NO ADS. FREE: 3 people, everything you log stays readable forever, and a few runs of the kit on the house. PRO, $2.99/mo or $19.99/yr: everyone on your roster, the kit, catch me up, the file filling itself, tonight, monthly wrapped. 7-day free trial on annual. for adults, 17+. — Subscriptions auto-renew unless turned off at least 24 hours before the period ends.

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.

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.
