One of the problems with the sheer number of ways there are of keeping in touch with friends, family and colleagues is that it can be hard to remember who is using which platform. Some of your contacts may like to use WhatsApp, while others prefer to stay in touch via text message or Facebook Messenger. This can mean that when you want to get in touch with someone it is difficult to track down their contact details – and this is something that TellyFon aims to help with.

At its heart, this is a unified contact list which pulls together your address books, phone number lists, contacts and more into one place. It means that there is no need to launch a messaging app just to see if the person you're trying to get hold of is using it. All you need to do it launch TellyFon, browse to the entry for the person in question, and you will see in an instant exactly which platforms they are active on. More than this, you can then click on their contact details for a particular platform to get in touch with them via the appropriate app.

The process of getting TellyFon up and running is largely automated as the app will – assuming you grant it the relevant permissions – pull in information from the various address books and contact lists you have littered across your phone. You may find that once all of this data has been collated into one central contact list, you have a fairly lengthy list of contacts. To help cut this down to size and for things to be more manageable on a day-to-day basis, you can mark individual contacts as favorites and add them to a VIP list for ease of access.

Platform support is impressive. In addition to phone calls and SMS, TellyFon also supports email, Facebook, YouTube, WhatsApp, Messenger, WeChat, Instagram, Twitter, LinkedIn, Skype, Kik, Viber, Line, Duo, Telegram, hike and Google accounts. Everything stored in the app if fully searchable so you can jump to a contact by searching for various pieces of data associated with them.

Perhaps one of the most useful features of the app is the message history function which can be used to track your communication with people across several messaging platforms.
