An app for long attention

Quire is a reading application. Its competitors are, by revenue, engagement products — they are measured on session count and return frequency, and their interfaces are built accordingly. Quire is sold by subscription and measured on whether people finish things.

That difference decides every screen.

The interface is the page

At rest, the reading view contains the text and nothing else. No chrome, no progress bar, no floating controls, no bottom bar that appears on scroll. Controls are summoned by a deliberate gesture and dismissed by the absence of one. Getting there required removing eleven elements the previous design had considered essential, each of which had a stakeholder.

Typographic engine

The measure is not fixed and it is not a percentage. It is calculated from the chosen size and family to hold between 62 and 74 characters per line at every viewport, adjusting leading as it goes — the relationship a compositor would manage by eye, expressed as a function.

Six families are licensed, each with its own optical size axis, and each tuned separately rather than dropped into a shared scale. A serif set at 17pt and a grotesque set at 17pt are not the same size, and the engine knows it.

What is deliberately missing

There is no streak counter, no daily goal, no social layer, and no notification that a book has been left unfinished. Each was proposed. Each was declined in writing, with reasoning, which is now part of the product documentation so the argument does not have to be had again next year.
