We need a simple app, with an interface similar to Grindr.
Overall, it requires the following few features.
1.) The user should create a profile, that can be accessed from any device (iPhone, android, or PC).
2.) There will be specific chat rooms (rather grindr rooms) and people will only be able to see those in the same virtual room as them.
3.) A person needs his own password (randomly generated QR code or string of characters) to access the rooms. These passwords must have a settable expiration date.
4.) QR codes/passwords will be different for each person to enter a room (not one password for each room).
We need this for Web, Android, and iPhone. Willing to hire a person for each one, if you can do any of this, contact me for the specific details.
We have to be able to communicate perfectly, so you must speak perfect english or Russian.
