On December 10, 2018, it was announced that Google is acquiring startup Sigmoid Labs. Our readers in the U.S. might not be familiar with that name, but if you live in India, you're likely very familiar with Sigmoid and their popular app "Where is My Train."

Where is My Train is used for tracking Indian Railway Trains and can be used entirely offline without any need for GPS or an active internet connection. It can be used in eight different languages, offers features like destination alarms, and is rated as the best travel app in all of India.

Commenting on the news, Sigmoid Labs said:

We can think of no better place to help us achieve our mission, and we're excited to join Google to help bring technology and information into more people's hands.

It's unclear exactly how much Google paid for Sigmoid Labs, but a report from ET back in August suggested that the search giant was looking to pay around $30 to $40 million.
