Is Badoo same as blendr?

Blendr is an online dating application based on geosocial networking for Android, IOS and Facebook. Blendr claims to be powered by Badoo but largely appears to be the same service.

What does hide on Badoo mean?

If you dont want to use your Badoo account for a while, you have the option to hide it. When your account is hidden, you will not appear in People Nearby or the Encounters game. Those who you have been in contact with before will still be able to see you in their inbox and can send you messages.
