Calmly Writer

Calmly Writer is a free online writing app that provides a distraction-free writing environment. It has a simple, unobtrusive and easy-to-use user interface that allows you to focus on what you want to tell. Calmly Writer is designed to help you write without any distractions and includes only the necessary features for writing such as formatting text. You can use it online or try and buy the application (cross-platform).
Calmly Writer is a great alternative to traditional word processors that include dozens of options for formatting text, distracting you from what really matters: writing. It has a minimal and neat design that makes it easy to use. However, it does not offer as many features as other writing apps.
