Customer Reviews

Very good but


I use nvalt on my Mac and wanted an iOS text editor that could work with my collection of notes on Dropbox. This seems to do everything I want but unfortunately I need the maximum font size to be bigger. Would be great if this could be changed!

As good as it gets for note-taking.


I have tried a number of markup based note taking/writing apps over the years and so far 1Writer is the only one that ticks all the boxes.

It has a clean, simple interface, which puts creation of a new note at the forefront, making it quick and easy to jot things down, but is also fast and simple to navigate the folders for filing notes.

Sync featues (I'm using DropBox) are fast, smooth, and so far reliable, but best of all it sync's/saves plain text files, meaning you can easily access the files created by 1Writer on other devices and platforms the app may not be avaiable on. The problem I had with alot of other mark-up editor products was that they either didn't support sync'ing or used propriatery librarys making access difficult outside the app.

The mark-up system is fairly standard and the keyboard shortcuts are well thought out. Another useful addition when comparing it to other products is in-line image insert. I'm not sure how this works without DropBox though as with DropBox sync enabled it uploads the image to DropBox and inserts a mark-up link to display the image.

Overall I would highly recommend it for note-taking, and on-the-go writing.



Having used several different text / note-keeping apps over the years I started using 1Writer about a year ago. I love it.

For a long while I used several text apps at the same time - partly because I was never entirely happy with any of them. 1Writer is perfect for me. It’s simple, quick, easy to use, and the dropbox syncing (I sync a folder using Dropbox that is shared with nvAlt on my Mac) has never let me down.

Whilst it can be very simple, it is also customisable with many extra actions and functions installed easily from the 1Write website web. These work in a way that adds functionality without complexity.

It looks great and works wonderfully well. And the ability to search within notes from the new iOS 9 spotlight feature is the icing on the cake!

I can’t recommend it highly enough.
