For the time being, the application allows users to send a voice note, as well as small audio clips. However, it has been announced recently that the new function will work similarly to Skype. The announcement also stated that the voice-calling function will be available within a few months. It has been revealed that iPhone and Android users will be the first ones to get the feature, after which it will be gradually rolled out to Windows Phone and BlackBerry versions.
WhatsApp is a free application which can be downloaded to any smartphone that supports Internet and users have to pay for the Internet connection only. People who use the app have to watch the tariff when they go on a holiday, as one has to be aware of the roaming costs.
The app is free of charge during the first year and after the trial period users have to pay a subscription fee of 69p on a yearly basis in order to continue using it. This is a lot cheaper than what users pay for a single text message. However, they have to keep in mind that deleting and re-installing the app will not renew the subscription.
