Nanu, an ad-supported app for Android which lets you make free app-to-non app calls has launched an enhanced 2.1 version with a group messaging feature which enables its users to connect simultaneously and collectively from their phone.

The group messaging feature will allow the users to send messages over Wi-Fi or mobile internet connection helping them save on sms charges.
With the latest upgrade, we are giving our users a holistic, end-to-end service that encompasses free and multi-dimensional connectivity in a simplified manner," said Martin Nygate, Founder and CEO of Gentay Communications, the firm behind nanu.

"Our commitment ensues towards building a better future by empowering people in emerging economies to enjoy free voice calls and messaging to anywhere in the world, irrespective of whether they have 3G connectivity or not," he added.
"We believe that the best things in life are free, and communication should be too.
The credits are equivalent to ten minutes of talk time for calls made to landlines or mobile phones within India, or 20 minutes of talk time for calls made to phones in the US.
Users will have 24 hours to utilise the credits.
During the Holiday period from 24 December 2015 to 2 January 2016 this will be increased to 40 free credits per day.
The app can operate seamlessly on 2G networks.
It also functions on ultra-low bandwidth and utilizes only 105 kb of data per minute, substantially less than rivals such as Skype and WhatsApp, which consume 875 kb and 740.
This has made nanu a huge success with consumers in countries like India where 3G connectivity continues to remain an issue.
In just a few months of its launch, nanu has attracted more than 1.6 million users in India.
