[APP][4.0+] "CMX" Crowd.mx -- chat and leave notes where you are... anonymously!

Hello XDA!

I'd like to present crowd.mx or CMX as we've started calling it. It's a location based anonymous chat / note dropping app. We've been working on it for some time and we think it's really cool and would like to share it with the community here at XDA.

CMX has 3 simple functions one on each tab:

[Tab 1] CMX connects you in a chat room with the nearest CMX users. We literally mean nearest. If it's late at night and nobody is on, it will get people from all over the world for you to chat with. If you're at a concert with a lot of users nearby or on at a busy time, you will only see chat that's happening nearby. You have your own personal 'chat sphere' that re-sizes itself for you to have people to talk with. That way, there will always be someone on for you to chat with. If you want to talk more privately, like most chat apps, you can select users and send them private messages.

We think Tab 1 is really frickin cool.

[Tab 2] If you like Tab 1, this tab is even cooler. Here you can leave public notes at different locations. The notes persist at that spot and can be seen in a 100m radius around where you dropped it. You can have a group meet you on top of Mt. Everest and have a private conversation there. You can leave a suggestion at a restaurant *in* the restaurant for people who eat there later. You could announce to your neighbors that you have a BBQ coming up. You don't just have to leave public notes, we even allow you to leave hidden notes which are only visible to the user you selected... even if that user is yourself. You could drop a note with your locker number over your locker or leave love notes for your wife. There are a lot of crazy interesting things you can do with this. Like many social apps, this aspect of our app really needs lots of users to be cool. That's why we made Tab 1... to keep you entertained in the mean time!

[Tab 3] This tab has two purposes. It mainly functions to let you control where you are. So if there's a major event going on somewhere in the world, you can go there and chat directly with the people there.

This tab also serves as a place where you can 'make an announcement.' Announcements are a premium service that you have to pay for. They're kinda like the big-brother to the notes in Tab 2. You can choose what radius you want them to be seen within and they will re-broadcast themselves to people chatting in the area.

Finally,

We've worked really hard to make this service as anonymous as we can. There's no login. No usernames. No facebook. No anything. You can get on and start chatting/dropping notes right away.

We welcome you to come join us in the chat, drop silly notes around town, and give us feedback so we can keep working to make this app cooler and more fun for everyone.

More Questions for the curious:

Q: Who made the app?

A: Myself and a friend, both of us recent physics phds... novice app developers!

Q: Where did the app come from?

A: A few years ago, we had a vision for a news app that would let the people report the news around them. While finishing our degrees, we worked on the infrastructure for the app in our spare time. Along the way, we came up with some pretty cool algorithms for indexing information by geography and other stuff. After we graduated, we set out to make that news app, but it was too big! So we looked at all the cool stuff we made for the backend and decided use it in a social app instead. So here's that app! We hope it's the first of many apps.

Q: What do you mean by anonymous?

A: Well, we really mean that we're committed to trying not to save or collect info from you. BUT, we have also taken extra measures to encrypt transmissions, encrypt data in the database, and discard information as soon as we don't need it. We'll continually work to improve on these as we get more experience. If CMX sees any success, we hope to hire experts far more proficient than us! If you're interested in more information about our security measures, we invite you to read our technical description on our message board. You can find the link in the playstore or in the app.

Q: Can I post anything?

A: Well, our hosting service does not allow porn. So you can 'report' people who have posted porn. And we can ban people who have posted porn. Also, we have protections in place to protect us from bot-spam.

Q: How can you ban someone for posting porn, if you don't track them?!

A: It's complicated. You should probably read the technical description mentioned in the anonymous section.

Q: How long will the app be in Beta?

A: Uhh, tough question!

Q: Why does it not show all the chat from when I was last on?

A: The messages sent to the Chat tab are *NOT* stored on our servers. They are redirected to the clients within range. So if your client loses its connection to our servers, you will not receive those chats. If your phone gets low on resources, it may close the service. We chose to do this to further protect people's identity.

Thanks! I hope you enjoy it.
