Feedback by users

This app looks very simple, but at the same time is quite customizable. It’s so convenient to use, I enjoy it very much. All your notes are stored as basic files and you can define the folder structure yourself. If you want, you can easily setup an external synchronization service to sync the notes to your computer. I think Markor really helps to stay organized. It is totally free and also open-source, which is great! Thank you so much for such a nice app. – Maryna K.

This is an incredible app. Being able to designate a file as a quick entry (grocery list file in my case) and a todo file (my todo.txt file) plus a share receiver that lets you choose recent files, make a new file, or whatever you like to add the text is outstanding. I didn’t know it did any of this when I downloaded it, I just wanted a good markdown editor and it is great at that. The other stuff was a surprise and perfectly fits my workflow.

The root folder of your files! Markor starts with this folder at the main screen and allows you to browse files. You can work at any (accessible) file & location with Markor.

What is ToDo?

Your main to-do list file in todo.txt format. You can access it by swiping once at the main screen, by selecting todo.txt at Notebook, or by using the dedicated launcher. You can also open it from Notebook or other apps! You will also have the option to create a to-do task when sharing text into Markor when the text is just one line. The location of this file is freely choosable and independent from the Notebook directory.

What is QuickNote?

The fastest and easiest way to take notes! QuickNote is a file in Markdown format with a freely choosable file location. You can access it by swiping twice at the main screen, by selecting QuickNote at Notebook, or by using the dedicated launcher.

A launcher is a “start menu option” in your devices launcher (=appdrawer / start menu). When Markor is installed you have the start menu option for Markor. When the Markor settings option “Launcher (Special Documents)” is enabled, you get the additional start menu options for ToDo and QuickNote. Note that a device restart is required when you change this option.

Format: Markdown

Most Markdown applications use URL encoding for links, so does Markor. This means replace every space with %20. This ensures that your Markdown content is compatible with most other Markdown applications.

Markor has a dedicated button for adding links and file references, which automatically applies this appropiate format. Take a look at this video to find out where the file reference button is located and how to use it.
