Tim Cook has spoken about his time as boss of the tech giant Apple. Mr Cook will step down as CEO in September. He revealed which Apple products he thought were less than perfect. He singled out Apple Maps, calling it a "really big mistake". In 2012, he recommended what he thought were more reliable map apps from Apple's competitors. He said admitting this was hard. The original Apple Maps was criticised for guiding drivers to strange places. This was because of faulty data and mapping errors. The places included non-existent bridges and businesses in the ocean.

Tim Cook became Apple CEO in 2011. He replaced pioneer and co-founder Steve Jobs. Cook transformed Apple from a $350 billion company into a $4 trillion company. It continues to generate huge profits and growth through products like the iPhone. Apple's brand represents a superlative lifestyle choice. Roughly one out of five people on Earth has an Apple device. Apple products are highly integrated in our lives. Cook said his greatest achievement was the Apple Watch. He said: "Apple's greatest contribution … will be in the health and wellness area."
