Plingm (currently named Freephoo on Apple's App Store) launches a free mobile VoIP app with SuperHD sound on the Japanese market. With the app, users can make quality voice calls to friends all over the world and cut phone bills substantially.

Plingm is a highly rated Swedish mobile VoIP-app that allows users to make free- and low cost telephone calls from mobile devices such as smart phones, tablets and iPod Touch. Unique for Plingm is SuperHD, an outstanding sound quality with a bit rate that is three times higher than other VoIP apps available on the market. The SuperHD sound has a natural sound where all nuances of the voice are captured.

"Switching from a regular phone to a mobile VoIP app with superHD sound is like going from cassette tape to CD. The sound is crystal clear, you can hear a pin drop, and mistaking "f" for an "s" is a thing of the past," says Plingm co-founder Pandelis Eliopoulos.

With an impressive consumer rating on App Store, this mobile VoIP app combines high sound quality with user-friendliness. Instead of a username, the regular cell phone number is used to call and receive calls, and only one account is needed for all your devices.

All calls made to another Plingm/Freephoo user are free, regardless where they are in the world and there is no time limit. Calling with this service instead of a traditional operator will save consumers large sums of money, particularly on international calls. At a low fixed rate, consumers can also call friends not yet using Plingm/Freephoo. This app is one of the first applications on app store that enables the user to purchase premium minutes through Apple's own payment system (In-App-Purchase.

Plingm/Freephoo has held the overall Top 1 position on App Store in three countries, the Top 1 social app in thirteen countries, and also received recognition from media and experts. The name Freephoo, which currently is used in App Store, will change name to Plingm.

Plingm uses innovative technology to develop and offer people friendly and cost efficient ways to communicate. The company was founded by entrepreneurs from the telecommunications- and internet industry. Plingm is based in Stockholm and active in 120 markets. More info on plingm.com
