is a geosocial networking mobile app geared towards gay and bisexual men, designed to help them meet other men in their area. Available for download from the Apple App Store and Google Play, Grindr comes in both free and subscription-based versions (the latter called Grindr Xtra).
The app makes use of a mobile device's geolocation, a feature of smart phones and other devices, which allows users to locate other users who are nearby.
Whether it's the early flirting stages or a long-term relationship, bisexual men and women on Reddit say they have noticed vast differences in their romantic encounters with people across the genders.
These range from how they show their emotions to what they are like in the bedroom - with one suggesting that sex with women 'tends to last longer'.
In January 2012, Grindr announced it was named the winner of Tech Crunch's 2011 Crunchies Award for Best Location Application at the Fifth Annual Crunchies Awards Ceremony in San Francisco at Davies Symphony Hall.
Separately, Grindr was crowned the winner of the 2012 i Date Awards in two of the 12 categories for Best Mobile Dating App and Best New Technology at the ninth annual Dating Industry & Internet Dating Conference in Miami.
The saying goes that men are from Mars, while women are from Venus.
And now, people who have dated both sexes have revealed that it sometimes really does feel like men and women are from different planets.

In January 2012, a software vulnerability potentially exposed the personal details of hundreds of thousands of users.
