Women-first dating revolution

Tinder co-founder Whitney Wolfe says she wants to disrupt the world of online dating - and cut back on the amount of online harassment directed toward women.

She describes her company Bumble as a "feminist dating app" where men are typically more polite, because women make the first move.

The company says it has around a million users who spend an average of 75 minutes a week on the app.

Ms Wolfe left Tinder in 2014 and sued the firm for sexual harassment before the lawsuit was subsequently settled with no admission of wrong doing.
