GROWLr is the dating app released by the dating service with the same name. If you're not familiar with this social network, it works similar to Badoo but it's only for men seeking men.
This app is completely secure and discrete with its users. All the information is kept private, and only other users can view your profile. After you create an account, you can browse through other user's profiles and start conversations.
GROWLr also has a great instant messaging service, where you can exchange messages and photos in real-time with other users. So if you're getting to know someone, you can send them photos directly, without having to upload them to your profile.
GROWLr is a great app for men interested in meeting users of the same sex. In theory, this app has over eight million users, so you're sure to find a bear near you no matter where you are.
