Grindr is also a location-based dating app, strictly for the gay male community. Grindr has more than 2.3 million subscribers in 192 countries [source: Li]. Grindr works much the same way as Skout: Sign up, create your profile and browse a grid of photos of men in your area. You can expand the photo to learn more information and send a text message or instant message to whomever nearby interests you.
Grindr is free to download for the iPhone, but Grindr Xtra gives you many more features for a subscription fee each month. Grindr Xtra has no banner ads, allows you to see more users per search, uses push notifications when a new person is in your area, can quickly send photos and can switch between multiple chats with people. For the Blackberry and Android phones, Grindr gives you a free seven-day trial of Grindr Xtra, then switches to a $4.97 per month subscription rate [source: Grindr].
