Helped by strong growth in number of users in India, phone directory app Truecaller said it has crossed the 100 million userbase milestone.
Truecaller allows users to identify unknown numbers, block unwanted calls, and search contact information among people and businesses.
The app has also doubled its daily new users in less than three months, Truecaller said in a statement.
As of November, India accounted for over 45 million users and 600,000 new users are being added every week from the country.
The Stockholm-based firm said it has also updated the app to focus on predictive style features, suggesting who to contact based on call history, time of day, and place.
The app has been fully redesigned to provide easier discovery and simpler navigation, and rebuilt to make it much lighter in terms memory consumption, it said.
"This is the first step we are taking to make Truecaller more intelligent and personal. We've made these advancement to save time for our users and make their lives less complicated when they want to get in touch with someone," Truecaller co-founder and CEO Alan Mamedi said.
In October of this year, the company received USD 60 million in funding from VC firms Sequoia Capital, Atomico, and Kleiner Perkins Caufield Byers.
In February, it had received USD 18.8 million in funding, led by Sequoia Capital, bringing the total investment in the company to more than USD 80 million.
Truecaller also runs another app, Truedialer, to offer users details of a person before the outgoing call is connected. Launched in October, Truedialer already has more than two million users.
