Dada - Your Circle app for iPhone and iPad

Dada aims to change the way you meet with new friends. It allows you to connect with strangers that you can see up to 200 feet away from you, with no Internet or cellular network needed. Whether you are, be it in a classroom or a library, in the subway or at the boarding gate, in a restaurant or at a bar, at a game or during a show, in a conference or in the air, Dada helps you connect and chat with people around through Bluetooth on your phone. After the first encounter, you can add your new friends as Dada contacts and keep in touch.

NEARBY USER:
Dada connects you with all Dada users nearby, even if their phones are in the pockets or bags. As long as nearby users are within reach of 200 feet, Dada uses Bluetooth to connect all of them in no time!

PUBLIC PROFILE:
Public profile is visible to Dada users. You can configure your own profile and only reveal the information you want people to know. Get to know other people by browsing their profiles before chatting!

TWINKLE:
Twinkle is a function that secretly expresses your interest in someone you see. If he/she happens to twinkle you back, you two will become friends automatically. The other person will only know your interest in him/her when he/she twinkles back. Otherwise it will be a secret forever.

PRIVATE CHAT/GROUP CHAT:
You can have one-to-one conversation with any Dada user, or chat with all of them in one giant chat room! With Dada, you can broadcast your messages to nearby users in the chat room or share pictures to certain people by creating your own groups!

FRIENDS/TAGS:
You can keep in contact with people you met after adding them as Dada friends. Dada groups all your friends by tags so you know who they are and how you met them. Once you become friends you can chat with them anytime, anywhere, without any distance limit.

DURABILITY:
Dada requires Bluetooth, which requires minimal battery consumption.

ALWAYS FREE:
No annual subscription fee or any hidden fee. Absolutely free.
