Writing apps for long stretches of text
Writing on a phone has always been fine for a paragraph and miserable for a chapter. The difference is not the keyboard — it is how much of what you have already written you can see while you write the next bit.
Prose is the one thing on this site that reflows perfectly, so the fold does nothing to the words themselves. What it does is restore context. A writing app on a phone shows you the sentence you are typing; a writing app on a larger screen shows you the sentence you are typing and the three paragraphs it has to follow from, plus wherever it sits in the structure of the thing. That is the entire argument of this list, and it is why the long-form apps are at the top and the quick-capture ones are at the bottom.
A keyboard is assumed throughout. Nothing here gets better because of the unfolded screen if you are typing with two thumbs on the cover display, and the apps built for drafting on a train are the ones that care least.
Order runs from apps built for manuscripts to apps built for getting a thought out of your head before it escapes.

Scrivener
Literature & Latte Ltd
The one built for things long enough to get lost in: a manuscript split into pieces, with the structure of it as a first-class object. The binder down the side is the feature, and on a phone the binder is a screen you leave the writing to visit. Unfolded, it is a column you glance at.

Ulysses: Writing App
Ulysses GmbH & Co. KG
A writing environment where the library, the sheet and the export sit in one continuous system across the Mac, iPhone and iPad, by the developer's own description. Three-pane apps are the clearest case on the site: the design exists, the phone just has nowhere to put the first two panes.

iA Writer: Get Focused
Information Architects AG
The strictest of them, and the one that has made deliberate decisions about what a screen of text should look like. Its whole proposition is a comfortable measure of type with nothing beside it, which is a proposition that benefits from a screen wide enough to leave margins on purpose rather than by accident.

Bear Markdown Notes & Journal
Writing · Shiny Frog Ltd.
Markdown with no account to create and a sidebar organised by tags rather than folders. Tags only help if you can see them while you write; folded, the tag list is a place you go, and going there is the friction the tag system was meant to remove.

Obsidian - Connected Notes
Dynalist Inc.
Plain Markdown files in a local folder, with links between notes as the organising idea. Writing from your own research is a two-pane job by nature — the note you are writing and the note you are drawing on — and one pane is why that workflow has stayed on desktops.

Day One: Daily Journal & Diary
Bloom Built Inc
Journalling, where the entry is short but the archive is the point: photos, audio and past entries on this day. A longer page means an entry and its photographs at once rather than in sequence, which is closer to how the thing is actually read back.
- 7
Pages: Create Documents
Apple Distribution International
A word processor in the proper sense, where layout is part of the document and the document has a page size that is not the screen's. Everything laid out for A4 or Letter is a zooming exercise on a folded phone; unfolded, rather less so.
- 8
Microsoft Word
Microsoft Corporation
The format everyone else sends you, which is reason enough for it to be here. Tracked changes and comments are the parts that need width — a comment in a margin requires a margin, and a phone has no room for one.
- 9
Google Docs
Google LLC
Collaborative editing, where the document is shared and the other people are visible in it. Suggestions and comments have the same margin problem as Word's, and the same fix.

Drafts
Agile Tortoise
Last, and deliberately: this is the app for text that starts somewhere and goes somewhere else, captured fast and sent on. It is designed around the phone being in one hand, and that is a design the fold does not improve. It is here because it is the app the others hand off to.
The selection and the order are ours. Each entry is written from that app’s own App Store listing, linked beside it, and this page from Apple's iPhone Duo product page. Drafted with AI assistance and checked back against those sources before publishing; the disclosure page explains how. The iPhone Duo has been on sale since 23 October 2026 and nothing here has been seen running on one, so what each entry says about the fold is an argument rather than a test.
