Every app with a page.
Each one is written from the app’s own App Store listing and carries the figures the store returned when they were last fetched. The shortlists are the editorial layer on top: which apps are on one, and in what order, is a decision rather than a query.

Amazon Kindle: Reading App
Reading
The page is the format that gains most from more glass, and for most people the pages already live in Kindle.

Bear Markdown Notes & Journal
Writing
Markdown notes with no account and no sign-up, in a sidebar that has spent years pretending it is not really an iPad layout.

Darkroom: Photo & Video Editor
Photo editing
RAW editing with the filmstrip, the histogram and the photograph itself all on screen at once, which a phone has never allowed.

Flighty – Live Flight Tracker
Travel
A flight tracker with an honest use for each screen size: the gate number on the small one, the whole trip on the large one.

Goodnotes: AI Notes, Docs, PDF
Notes & PDFs
Handwriting, PDFs and an infinite canvas: three things that have never fitted on a phone at a size you could work at.

Ivory for Mastodon by Tapbots
Social
Tapbots' Mastodon client, from the team behind Tweetbot, and the kind of timeline app that historically grows a second column the moment you give it room.
Lake: Colouring for Adults
Drawing
An Apple Design Award winner from 2017, built on hand-drawn pages by independent artists, whose developer says the current version is reworked for the iPhone Duo's unfolded canvas.

LumaFusion
Video editing
A multi-track video editor you buy once, built around the one piece of interface that cannot be made taller instead of wider.

Overcast Podcast App
Podcasts
The honest entry. The screen changes this one least, and it is here for what happens on the other half of it.
