FreePP

FreePP is a completely free instant messaging tool similar to LINE or Viber that lets you send text messages or call any of your contacts.

With FreePP, however, text messages and phone calls are just the tip of the iceberg. From its messaging interface, for example, you can send any type of file, such as videos, text documents or songs. You can also use fingertip handwriting and drawing tools included in the app.

As usual with messaging tools of this sort, FreePP offers a wide range of emoji and stickers you can use to decorate your conversations.

Another good thing is that you can use FreePP on both mobile phones and tablets. Once you create a FreePP password, you can use your account on any Android device.

FreePP is a powerful, comprehensive IM tool that not only offers more features than many of its competitors, but also has a simple and elegant interface.
