Best so far; wish I could “select line.”

I’m a writer and I’ve been through a number of text editors for iOS. When my last favorite one wilted and died due to lack of support, I set out to find a really good one. Various sources steered me to 1Writer, and I discovered I’d already bought it in the past but never used it. I reinstalled it, set it up to sync with Dropbox, and have been happy ever since. My previous text editors would often not allow me to create new files unless I was online or had a data signal (because I had them set to sync with Dropbox), but 1Writer doesn’t give me that trouble.

The one thing I really miss from my last, now dead, text editor was the option to “select line” when you touch and hold and get the usual “select” and “select all” options. Often, it would be convenient to select a line or paragraph without having to drag the beginning and ending markers hither & yon using a touch screen. So pleeeeeeeeease add that, okay? Thanks!

Love this app; much cleaner than Drafts. In-place editing not ready yet.

Have been really enjoying this app so far. I started experimenting with TextExpander and one thing I would really like to see is better support like Drafts has. For example, when expanding a snippet with placeholders, Drafts actually opens up the TextExpander app so that you can fill in the placeholder and then returns to completed text to the Drafts app.

Also, trying to edit in place inside Dropbox seems to be buggy. It constantly tries to update the file while it's still open, which has caused me to lose some work. I haven't bothered with that since first trying it. I do appreciate the Dropbox integration. One thing I would like is the ability to create the new files inside a Dropbox folder of my choice so that they are available on all devices. What's the point of saving something locally? Maybe this feature is there and I just haven't found it yet.

EDIT: thanks for the response. To clarify, I meant setting the default location of NEW files to Dropbox. In other words, having the new files when I open the app automatically save to Dropbox instead of to the device.

EDIT 2: Well, this feature is already there. Never mind!! Thanks for the response once again.

Overall a five star app; improved TextExpander support would really make it nice for composing emails with templates and placeholders. Please add it!

Thank you so much for the 5 star review! You can change the default folder in 1Writer > Settings > Default Folder.

Remains awesome

Prior to getting this app, I had tried around 30 “mark down-capable, cloud-connected“ iPhone apps to integrate with many notes stored in many folders on dropbox.

I first tried Simplenote and some others, I think 2011-ish, because I was unhappy with Evernote‘s lock-in of my text notes, and I had heard Merlin Mann and some other respected tech folks explain plaintext and markdown.

Over the years, some apps would work for a while, then not.

I switched to 1Writer in 2016 or 2017, and I liked the interface, the favorite folders, and the tag support.

After having years of problems with apps not being able to handle dropbox synchronization without bogging down, crashing, duplicating data, etc., I was prepared for this app to eventually fail as well.

Good news for me – it did not fail, and the synchronization has been amazingly good – no crashes or duplicates, no need to restart the synchronization all the time.

Even if I don’t synchronize for a while, then go back into the app and rubber band to refresh, and then leave the app, when I return, everything is synced up nicely.

I have no time to write reviews, but my sense of gratitude for this great app compels me to share the goodness, so there you go :-)
