If you had trouble locating your Uber app sometime today, it's because they released a new logo. Users will now see colourful geometric shapes, which unique for each market and if your are a drive or a rider. This new move is to reflect 'what Uber actually is -- a transportation network'

Now, the man behind it has revealed he has left the company.

In a Medium post, published just 24 hours after Uber's branding unveil, Andrew Crow explained that he is 'using our recent successes as a chance to take time off to rest, reflect, and recharge. '

'Today, I am moving on from Head of Design & Brand at Uber,' he wrote.

'I leave an amazing team who works to create great experiences, shaping the way people and things move through the world.

The new logo aims to reflect 'what Uber actually is - a transportation network', the company said.

But many have ridiculed the strange design for being nothing more than a corporate re-branding exercise.

'The old Uber was black and white, somewhat distant and cold,' Travis Kalanick, Uber's CEO and co-founder, wrote in a blog post.

'This belied what Uber actually is – a transportation network.'

The iconic 'U' is now a circle with a square in the middle set on a colourful background for riders.

If you're a driver, you will see a hexagon with a square in the center and again set on a colourful background.

All of the rebranding of the firm was done in-house and logos began as concepts instead of just icons

INSPIRATION FOR THE LOGOS During their brainstorming, the team focused on a blog post Kalanick wrote in 2013, 'Bits & Atoms', which compared Uber to bits and atoms. Bits is the firm's technology – Uber's mapping and dispatch software. And the atoms are a representation of the people. Another concept emerged in the drawing board of small square tiles, similar to the ones that line bathroom floors. The team agreed on a design and decided to use colours, patterns and images unique to each specific market. Uber says it was inspired by Mexican pink and patterns in the local tiles in Mexico. In Ireland, the Georgian architecture and lush greens will be highlighted. And in Nigeria, from the Ankara, which 'came up again and again because of its bright colours and beautiful geometric patterns'. Advertisement

In 2014, Airbnb was forced to defend its controversial new logo, claiming it will become as recognisable as the Nike swoosh. However, many believed it looked more like a vagina.
