If you edit plain text files sometimes or just write notes and save them to your phone (tablet), take a look at Coastline text editor. It is lightweight, simple and minimalistic text editor for android. It supports basic text editing features:
  • Opening, editing and saving plain text documents
  • Changing font face and size
  • Changing line height
  • Autosave
  • Remeber last opened file
  • "Keep screen on" feature
  • Automatic .txt extensions
  • Dark theme
  • Sending text by email, sharing in social networks, transfering text to other apps.
  • Support both phones and tablets

Supported interface languages:
- English
- German
- Russian

There are some screenshots in attach.

The application is fast and clean (at least, we believe it is ). And we'll try to keep the editor as simple as possible.
Also, please, note that Coastline is not an office application or full featured note taking app.
Download it from Google Play Store: just search "coastline text editor" or "com.rumsunrise.coastline" in the Store.

Enjoy! Feel free to ask questions and give us any feedback

its a nice editor..
i like its lightweight & minimalistic design!

just a few suggestions..
- option to display line numbers
- option to word-wrap or not
- font sizes smaller than 16 (good for display on small mobile screens)
- undo/redo
- search within text

i consider the first 2 "should-have" features of all text editors..
for the others 3, "nice-to-have" features..

iamelton, thanks! It is nice to know you like the app.
We plan to add undo/redo and search. As for other features - maybe, but i cannot promise. Initially we did not plan to implement them.

Hi all!

We've released a new 1.5.5 version of the text editor. Well, what's new here:
  • "Keep screen on" feature. Switch it on if you want the screen to stay awake while the editor is running
  • Automatic .txt extensions. If you need something different - erase .txt and put something else
  • Dark theme
  • Last, but not least: some bugfixes

There is also a new translation - German.

Download new version, as usual, on Google Play Store. Enjoy!

I'm glad to announce new Coastline 1.6. This is an important update and we hope you'll like new app. In this version we basically focused on the new design and some UI improvements.
First of all, ver.1.6 supports Android 5.0 and Material theme. In general, we like new Material design due to its simplicity and clean minimalistic look. And, of course, you can use new editor both on android 4.x and android 5.

What's new:
  • New design, Android 5 support
  • Improved dark theme
  • Improved themes switching
  • Better Save and Open screens
  • Better Settings screen
Update your app or download new version of Coastline at Google Play Store.
Please, note: there is new permission - Internet access. We need this because we placed some links at the About screen.
