Huge performance boost


This update provided a huge performance increase in my 10,000+ textfile journal. This app is a much better solution than IA Writer, primarily due to library and file management. IA relies on iCloud, meaning when you get on a jet you may or may not have a local copy of your files. With 1Writer you are sure you have everything, and that all the work you do offline will be loaded the next time you connect. Also: the #tag system is the best implementation anywhere, including Mac apps. If you are using any kind of zettlekasten system, like the FSIM, this is the perfect app. So much better than the old WriteRoom, which I loved, and as mentioned IA because of the library system and tagging.

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.

The best out there for IPhone.

KJAY on the Bay

I bought this app the first week it was on the App Store and I’ve been using it almost daily since. It’s got all the features most would want and since it’s release it has been updated almost continually by the Dev. If it doesn’t have a feature you think you might need, wait a month and it probably will. It’s easy to use and has a robust filing system searchable by title, date, sub file, or hashtag.
As I said, this is the best text editor currently available for IPhone . Well worth the price.
