Glance, which serves media content, news, and casual games on the lock screen of Android -powered smartphones, has amassed 100 million daily active users, it said today.

The subsidiary of ad-firm InMobi Group reached the milestone in 21 months in what appears to be the shortest duration for any popular internet service to gain their first 100 million daily active users, said Naveen Tewari, founder and chief executive of InMobi Group, in an interview with TechCrunch.
