# RaveGang **Find your gang in the dark.** An offline proximity finder for festivals and crowds. Free, Android, no account, and it never touches the internet. - Website: https://ravegang.com - Download (Android APK, v0.1.0, 5.4 MB): https://ravegang.com/assets/ravegang-0.1.0-30cac82d.apk - Privacy: https://ravegang.com/privacy - Made by AGENSUM, LLC — https://agensum.com — hello@agensum.com ## What it is A radar for your crew that runs on nothing. Your phones find each other directly over Bluetooth, and other phones in the crowd relay the encrypted traffic they cannot read. There is no cell signal, no SIM, no Wi-Fi, no server, no account and no tracking involved in finding someone. Up to 16 people can be in one gang. ## The problem it solves At a festival, everything you would normally use to find a friend needs the internet, and the internet is the first thing a festival takes off you: - **Data is a rumor.** Full bars, nothing moves. Forty thousand phones on one cell tower at drop time. Your message sends at 4 AM on the walk home. - **Live location isn't live.** Every share-my-location app is a round trip to a server. No server, no dot — just a pin frozen where they stood an hour ago. - **Meet-at-the-flag never works.** Someone's at the wrong flag, someone's in the bathroom line, someone went home. ## How you use it 1. **The ceremony.** One person starts the rave standing at the venue and holds up a QR code. Everyone scans the same code. Each phone that joins glows its own color, so you can name your friends while they're standing right there. Not together yet? Send them the invite instead. 2. **The radar.** Everyone is a diamond on a wireframe field. The color is who they are, the ring is how many hops through the crowd their signal took, the glow is how fresh it is. Statuses: VIBING, SUPPLY RUN, ON MY WAY, CAMP, COME TO ME, TOILET, SOLO (private), CAMP, FINALE. 3. **The arrow.** Tap a name and the screen becomes one arrow and one distance. Hold your thumb on the reticle and sweep — it ticks in your palm when you're pointing the right way, so you can find someone without reading anything. ## How it actually works - **Off the grid on purpose.** No towers, no Wi-Fi, no back end, nothing to log into. Put the phone in airplane mode with Bluetooth on and the radar carries on exactly as it was. - **Sealed to your gang.** The encryption key is generated on your phone and never uploaded. The only copy that leaves is the invite you hand your friends. - **The crowd is the range.** Strangers running RaveGang relay your sealed traffic without joining anything or seeing anyone. The busier the field, the further you reach. - **Built for hour nine.** Deliberately frugal with the radio — a finder that flattens your phone by midnight is not a finder. - **It forgets by itself.** A rave expires on its own, and calling the FINALE ends it early: one shared RAVE COMPLETE, then it is gone from every phone. - **One optional download.** You can pull an offline street map of the venue before you go. That checkbox is the only moment the app uses the internet. Reach depends on bodies, not on a spec sheet. Across an open field it is a long way; a wall of people between two phones eats a lot of it. That is what the relay is for — your reach is the crowd's rather than one phone's. It is also why the radar counts hops instead of meters: it will not invent a number it cannot measure. ## For festivals and events The denser the crowd, the better it works. Nothing goes on site: no beacons, no Wi-Fi, no back end, no data deal. Coverage grows with how many attendees have the app rather than with what you spend on hardware. - Spare phones become relays — an old phone on a charger at the info tent, the bar or the camp gate carries sealed traffic for everyone, joins no gang and reads nothing. - There is no attendee database to hand over, because there is no server. - When the cell tower folds at headline time, this is the one thing on site that does not notice. No festival has run it yet. To be the first: hello@agensum.com ## Getting it - **Android 8.0 and up.** Bluetooth and location permission are required, because Android hides every Bluetooth scan result without location permission. Your location is not uploaded anywhere. - **Not on Google Play yet.** The download is the same signed build the makers run themselves, served from this site. Android will ask you to allow the install because it did not come from a store. - **iOS is in development.** No date is being invented. There is an email waitlist on the site: one message when it ships, then silence. - **Free, no ads, no subscription, no account.** There is no data to sell because none is collected and the app has nowhere to send it. If it ever earns money it will be from festivals and events, not from users. ## FAQ **Does it really work with no signal?** Yes, and that is the only way it works. Nothing in the finding path touches the internet: phones talk straight to each other and hop through other RaveGang phones nearby. Airplane mode with Bluetooth on is a perfectly good way to run it. The one optional exception is the venue street map, downloadable in advance. **How far does it actually reach?** It depends on bodies. Across an open field it is a long way; a wall of people between two phones eats a lot of it. The relay is what makes your reach the crowd's rather than one phone's. The radar counts hops instead of meters because it will not invent a number it cannot measure. **Who can see where I am?** The people holding the key you handed out, and nobody else. Everything on the air is sealed with a key made on your phone, so the strangers relaying it cannot read a thing. There is no account, no server and no log, so there is no copy of your night anywhere. Set yourself to SOLO and your position stops going out at all while you still show as present. **What does it do to my battery?** It is built for hour nine at 8%. It sips the same kind of power earbuds and watches live on all day, and spends more only when it has to. Plug a phone in and leave it still and it becomes an anchor that quietly boosts the gang. **Do all my friends need it installed?** Everyone you want on the radar, yes. There is no phone number to look up, so the app on their phone is the only way yours can hear them — one scan of one QR at the gate. Strangers with the app help you without joining anything. **Why isn't it on the Play Store yet?** Because it is not finished being tested in the one place that counts, which is a real crowd. The download is the same signed build the makers run themselves. Android's install warning is Android doing its job, not a sign something is wrong. It goes on Play when field testing says it is ready. **When is the iPhone version out?** It is being built, and no date is being invented. The waitlist on the site sends one message when it lands. Until then, one Android in the group can hold the gang together for everyone standing near it. **Is it free? What's the catch?** Free, no ads, no subscription, no account. There is no data to sell because none is collected. If it ever earns money it will be from festivals and events.
