Secret signals for your closest friends.

The basics
What is a Bro Book?
A Bro Book is your group's shared list of secret code words. Each entry pairs a phrase your friends will recognize with the private meaning behind it. Here are a few to get the idea.
Call me in 2 minutes.
Abort the plan. Stop talking.
I'm uncomfortable — check on me.
Give me an excuse to leave.
These are just examples. In the app you write your own — as goofy or as practical as your friendship needs.
Features
Everything your crew needs to stay in sync
Built to feel private and fun — a little secret language that travels with you.
Your own Bro Book
Build a shared dictionary of code words with your friends — each one maps a phrase to a private meaning and a suggested action.
Quick Signal
One tap fires a code word to your whole group. They get the signal — and the agreed meaning — without anyone outside the crew having a clue.
On-device Decypher
Paste a message and Decypher scans it for hidden codes right on your phone. No text is ever uploaded — the matching happens locally.
Works offline
Look up a code or decypher a message with no connection. Your Bro Book is cached on your device, so signals never depend on signal bars.
Private by design
Start anonymously — no phone number, no real name needed. Your codes live only in your group, and we never sell or share your data.
Free to use
BroCode is free for you and your friends. We keep the lights on with unobtrusive ads — never by selling what you say to each other.
How it works
From zero to secret signals in three steps
Create or join a group
Spin up a Bro Book in seconds and share the invite code, or hop into a friend's. Your crew, your rules.
Add your code words
Agree on phrases everyone will remember — "Pineapple", "Red Card", inside jokes — and give each one a meaning and an urgency.
Signal or decypher
Fire a Quick Signal to the group when you need it, or paste a message into Decypher to reveal any codes hiding inside.
On-device Decypher
Hide a message in plain sight
Slip a code word into a normal text. Your friend pastes it into Decypher and the hidden meaning pops out — all without leaving their phone.
