Careful software for everyday life.
Eiderlane is an independent software studio. We design and build apps for iPhone and the desktop, and the websites that go with them.
A studio that ships whole products.
Eiderlane LLC takes a product from the first sketch to the store listing: the design, the app, the website, the pricing and the support that follows. Every product gets the same team from start to finish, and we keep looking after what we ship.
Design and engineering, under one roof.
Apps
Native iPhone apps in Swift and SwiftUI, and desktop apps for macOS and Windows. Built to work on the device wherever they can, with nothing sent anywhere it doesn't need to go.
Websites
Product sites, learning platforms and online stores that load quickly, read clearly and work on every screen, from a phone to a wide desktop.
Product design
Interface and experience design, from the first wireframe to a finished design system, with accessibility built in from the start.
Products and sites we've made.
Our own app, Ruminate, and a selection of products and websites we've designed and built.
Ruminate
Our private voice journal for iPhone, built so that what you say stays with you. In testing now, and coming soon to the App Store.

Private by default
Our apps keep your data on your device wherever they can. Ruminate has no server at all.
Plain language
Clear prices, clear policies and no dark patterns. If something has a cost or a limit, we say so up front.
Built for everyone
VoiceOver, Dynamic Type, Reduce Motion and readable contrast are part of the work, not an afterthought.
Looked after
We answer support email ourselves and keep fixing and improving what we ship.
Notes on design and the craft.
Essays on how we think about privacy, interfaces, typography and the business of making software.
Privacy is a design decision
The most private data is the data you never collect. Why we decide where data lives before we draw a single screen.
ColorAccessible color without the guesswork
How perceptual color spaces and contrast checks turn a palette from a matter of taste into something you can test.
