## What is Bigger Blacker Book?

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.

### 5/5 — Always improving

*2026-05-08, version 13.4.3*

This app is exactly what I want. New features are added and feedback is taken very seriously. Bugs get fixed (unlike Grindr). I wouldn’t go with any other.

### 1/5 — Crashes on reports

*2026-05-08, version 13.4.3*

Can’t access years of data

### 1/5 — Always Broken

*2026-01-23, version 13.0*

Ah yes, another day that ends in “Y” and this app just…doesn’t work. Remove it and the re-add all the info back…and then two days later it just random breaks and you have to delete it and start over.

### 1/5 — Constant error

*2026-01-14, version 11.5*

I like the app but I have received the error below quite often and even on multiple devices.

Unexpected error occured
Apologies..The app will close now
Please restart the app
Signal 6 was raised.
(null)

### 4/5 — The best sexual heath tracking app for gay men

*2025-12-17, version 11.5*

Love this app. If the date filtering in the analytics section worked correctly. It would be 4 1/2 to maybe five stars.

### 3/5 — Fix the Location issues!

*2025-11-30, version 11.5*

Allow us to just fill in the location - whatever is currently feeding the location field is giving me cities that are actually neighborhoods in my area. Also just randomly doesn’t work, so I can’t list a new encounter.

### 3/5 — Great App, Lacks Stability

*2025-09-19, version 11.5*

The app is incredible well thought out and designed. It’s unfortunate you never know if the app will be working when you go to use it or not.

### 5/5 — Always improving

*2025-09-01*

This app is exactly what I want. Feature requests are honored and bugs get fixed. I wouldn’t go with any other.

### 3/5 — Broken

*2025-08-26, version 11.5*

Used this and was glitchy and it broke. Then they updated it and it was better than ever.  Ow broken again. No response from developer after submitting logs.
22May2025:
They just updated it again, but the weight category is artificially limited to 63 kg for some reason. Glad it works again, sad it’s still glitchy.
Update:26Aug2025: still needs work: height area broken, place area broken for some basic places; if you leave app, it often throws away data (doesn’t auto-save), opening a closed file often has app throw away data. Needs lots of basic work

### 4/5 — App is great if it would stay that way would be great

*2025-08-20, version 11.5*

App is great in idea and fills a great need. Unfortunately, app has crashed twice in the past couple of years and support was unavailable. Backup to iCloud did not work. App has been running well since May. I hope that the crashing and loss of info will be a thing of the past. I love this app - I’ve started over 3 times so that shows something. The app has so many customizable features that make record keeping great with statistics and health tracking. Fingers crossed app will continue to be outstanding.
