article: Kim Kardashian is undoubtedly the queen of self-promotion, posting 'selfie' snaps to her millions of followers on a daily basis and even releasing a book filled with her self-taken pictures. And now, Kim's secret weapon to achieving the perfect photo has seemingly been revealed. Buzzfeed is convinced that the social media superstar has been using FaceTune to edit her selfies - a £2.99 photo editing app designed to help you edit your portrait photographs into 'perfection'. Scroll down for video . Spot the difference? Bianca London and Martha Cliff used FaceTune to edit their selfies. The £2.99 photo editing app is designed to help you edit your portrait photographs into 'perfection' - but the results were rather scary... and obvious . Not only can you remove spots, improve skin texture and enhance eyes, but you can also fix grey hair, reshape your face and even fill in bald patches. You can also whiten teeth, remove wrinkles and elongate or shorten a face entirely before instantly sharing the retouched photos to Facebook, Instagram, Twitter, Flickr or Tumblr, or via email. Most of the tools are easy to use and you simply have to zoom and pan, then use your finger to paint on the effect. FEMAIL's Bianca London, Anucyia Victor and Martha Cliff tested it out to trim down their figures - with quite startling results. Anucyia Victor, left, before, and, right, after, tested out the tools, which are easy to use - you simply have to zoom and pan and use your fingers to alter your waistline . The founders of the app - which FEMAIL tested: before, left, and, after, right - say they have a strong background in the academia, which they used to take the most exciting, state of the art technologies and integrated them into a product in the most user-friendly way . The 'reshape' and 'resize' tools let you modify your figure by lengthening your legs, sucking in your waist or trimming down your arms. It is, however, slightly obvious what you're up to. One look at the background of the image and you can see the wall has a curve and is slightly distorted. Countless celebrities - including Beyonce, Kendall Jenner and Kim Kardashian - have been called out on mishaps like this by savvy social media users. Not only can you remove spots, improve skin texture and enhance eyes with the app, but you can also fix grey hair and reshape your face. Martha Cliff, left, before, and, right, after using it . The app, which Bianca London, left, before, and, right, after, tried out, claims to give any user the ability to achieve high-end, realistic looking results, comparable only to what a professional can achieve on the desktop with Photoshop . The app's founders do, however, think they're onto something with their latest offering. 'Facetune is different,' said Zeev Farbman, Lightricks CEO. 'Unlike other apps, it gives any user the ability to achieve high-end, realistic looking results, comparable only to what a professional can achieve on the desktop with Photoshop.' He then explained how this was achieved: 'We have a strong background in the academia, which we used to take the most exciting, state of the art technologies, that were never seen on mobile devices, and integrated them into a product in the most user-friendly way. 'With the tiniest bit of effort, everyone can get great looking photos of themselves.' And it seems that our image conscious society are rushing to improve their cyber image because when it was released, it was the third most popular app on iTunes just behind What's App and the Catchphrase game. Photoshop master Peeje T told RadarOnline that shots of Kim and her pal Blac Chyna on Instagram may have been 'manipulated' to enhance the Keeping Up With The Kardashians star's shapely figure . Drawing the background of one of Kim's pics as an example, Peeje T. explained the slight curvature of the door frame could be proof that Kanye West's wife has been digitally doctoring her snaps . Kim often showcases her trim figure on her Instagram page via a series of selfies but some experts say her waist appears smaller in her selfie (left) compared with pictures later taken by the paparazzi (right) While some of her Kim Kardashian's Instagram snaps, left, have no apparent signs of distortion, she does appear slightly different - perhaps due to a filter - to paparazzi shots from the same event, right .
