HerSmile is an online dating site and app launching on International Women's Day, which aims to make sure users' intentions are sincere.
Female users pay a monthly subscription of £12 ($17), while men buy introductory credits. Men have to spend one of their credits to send their first message to a woman, and if she's not interested then the credit is returned. The site claims this will prevent women from being bombarded with messages, as men have to commit their credits only to people they're genuinely interested in.
"By protecting women online and ensuring men aren't misled we can considerably reduce the time taken for both sexes to meet a genuinely suitable partner," explained Cosmo Currey, the site's founder, in a press release.
