Bigger Blacker Book is a private sexual health and encounter tracking app built for real life — not shame, guesswork, or awkward memory gaps. It helps you record sexual encounters clearly and flexibly, capturing the details that matter to you without forcing labels or assumptions. Your history stays organized, searchable, and entirely under your control, so you can make more informed decisions without relying on memory alone. Beyond encounters, Bigger Blacker Book helps you manage your sexual health over time. You can track STI screenings, medications, and reminders, keeping everything in one secure place. Optional features let you share status information when you choose, while keeping your data private by default. Originally built to serve queer communities and informed by lived experience, Bigger Blacker Book is designed for anyone who values honesty, autonomy, and better tools for managing their sexual health — without judgment, gamification, or pressure. See our EULA (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/), Privacy Policy, and Terms of Use on our website or in the app. Your data belongs to you. Nothing is shared unless you decide it should be.

Food logging doesn't fail because of willpower. It fails because of the work: search the food, pick the portion, type three numbers. PFCnote removes that work. ■ Talk Say it to the ChatGPT or Claude you already use, in your own words. "The usual breakfast. Chicken salad and a rice ball for lunch. Protein shake as a snack." ■ It's logged Protein, fat, carbs and calories are recorded as you said them. No food search. No number entry. You don't even have to open PFCnote to log. ■ You see it Open the app and today reads as one page: intake vs. goal in kcal, what's left, and everything you ate. ■ "The usual" works Say "the usual breakfast" and the AI rebuilds it from your past entries. No retyping the same three items every morning. ■ Once it's logged • Ask the AI: "Will I lose weight eating like this?" "Am I getting enough protein?" — answered from your own records • See the change: weight trend and average daily intake in plain numbers, before any chart • Fix it: every AI estimate can be edited by item, amount and P/F/C • Goals: set daily P/F/C and a target weight (calories convert automatically at 4/9/4) • Apple Health: optional weight read/write • Manual entry: add or correct without the AI • Start without an account: sign up later and your records carry over ■ Made for you if • You gave up on calorie apps because of the typing • You track macros for a cut or a bulk • You already use ChatGPT or Claude every day ■ Please note Macros and calories include values estimated and converted by AI. They are not guaranteed to be accurate and are not a substitute for dietary or medical advice. Connecting requires a ChatGPT or Claude account (a plan supporting custom connectors may be required).
