Ever stuck for where to go for a late night drink or meal in London?

My friend Emma has the answer for you with her 24 Hour London app (available on iOS and Android). The idea behind the app is to provide people with information about bars, restaurants and clubs that are open late at night with the added bonus of special offers of discounts and even free drinks at some of the establishments listed.

The app is in early stages but is gaining a following and Emma's on a mission to capitalise on that. Londoners, if you're ever out and about at night, then do download the app - it's free and I expect you'll find it useful.

As part of Emma's initial marketing push, she's using Thunderclap to help spread the word about 24 Hour London in January. Thunderclap simply posts a tweet or a status update on your feed at the time and day allotted and that's it. It doesn't ask you to connect your contacts or spam your friends by email. It costs you nothing save for a few moments of your time.

Your assistance will mean more downloads for her and more footfall for the venues she works with and maybe free drinks for you and your friends if you use the app. Plus, you'll probably find out about places near where you live or work that you never knew opened late at night. I'm also really interested to see how this campaign works. I've never tried Thunderclap. If there's any insight from the campaign, I'll share it here in due course.
