Almost there


I appreciate the adoption of iOS 11 files features but wish it went further. Specifically I still find it a bit confusing and cumbersome figuring out the different ways this app interacts and syncs with storage.

I very much like the Pages interface. I’d like to just browse and view files through a Files interface like that, and not have to deal with special folders and a custom UI and direct Dropbox integration and so on. I open the app, I browse my file system, and I can choose to create a new file in any arbitrary folder. That is the ideal. Open-in-place comes close but is not quite there.

Fantastic Customer Service


I originally downloaded this app as a replacement for Plaintext 2, who went out of business and stopped supporting the app. I had some issues with the .txt files I saved pulling up in other programs showing symbols instead of quotes. I shot an email to them when I was just about to give up, and quickly received a personalized response and fully detailed answer to my question (basically turn off Smart Quotes and Smart Dashes in 1Writers Settings).

Fantastic App
Awesome Customer Support

Fantastic text and markdown editor.


I was looking for an iCloud Drive based text & markdown editor with Open In Place support (so I could open files from other folders or other app containers through the Files app). This is exactly what I was looking for.

I have only a couple feature requests:

1. In the Keyboard toolbar, always show a “hide Keyboard” button instead of only on one of the pages.
2. Enable quick access to edit mode: if in preview mode and you double tap in a document, it should switch to edit mode and move the cursor to where you double tapped.

Great work! Looking forward to future updates, but it’s already exactly what I needed 👍
