Zesty.co.uk launched this time last year as an online portal for booking last-minute dentist appointments at clinics across London. While it's no doubt been useful for anyone that needs an emergency (and likely extortionately priced) filling, the site has now expanded to help you access other healthcare services at short notice. Whether you're in need of a chiropractor, osteopath, physiotherapist or sexual health professional, you can use Zesty to check for open appointments in your local area. You can even book in to see a GP, but only at private clinics -- for a short-notice slot at your own NHS surgery, we're afraid you'll still have to be on the phone by 7am. In its quest to "make healthcare appointments as easy as ordering a pizza," Zesty plans to go almost UK-wide later this year and release a native app to compliment its mobile-optimised site. Before you get the wrong impression from Zesty's strange tagline and accompanying imagery: your pizza delivery guy is not qualified to give medical advice.
