Services

Design and engineering. One team, from the first sketch to the App Store.

Sebastian and Andres lead every project, with designers and engineers we have worked with for a decade. The people who design your app also build it, so nothing gets lost between the two.

01 · Product design

Apps people keep.

Brand, interface, motion and film, made by the people who will build it. A collectible app with a million creatures, a puzzle cast in four materials, a game you play with your face.

  • Brand systems and characters
  • Interface and interaction
  • Motion, film and the launch site

02 · Native engineering

Fast, private apps for Apple devices.

Native apps in Swift for iPhone, Apple Watch, Vision Pro and the Mac. Bluetooth that reconnects, graphics that stay smooth, and AI that runs on the device instead of a server.

  • iOS · watchOS · visionOS · macOS
  • Bluetooth, sensors, real time
  • Metal and on-device models

03 · Connected health

Health apps that cannot fail quietly.

A decade of building medical alerts taught us what goes wrong between a sensor and a person: phones that sleep, sensors that drop out, alerts that never sound. We build for all of it, with the documentation regulators expect.

  • Sensors, alarms and delivery
  • IEC 62304, IEC 60601-1-8, Section 524B
  • Inside your quality system

04 · Lightline films

Your hardest idea, explained.

A film in one drawing: a single light acts out your product, device or discovery while the reader scrolls. Narrated, cut for social, and delivered in two weeks.

  • Scroll film · 60 to 90 seconds
  • Narration · 3 to 5 social cuts
  • $12,000 · two weeks

The offer
How a project runs
WhoSebastian or Andres, on every project. Designers and engineers we have worked with for a decade join when the work needs them. You talk to the people doing the work.
ProjectsA new product, a redesign, or one of us in your team. From the first sketch to the App Store, or in your codebase from your next release.
TestingReal devices from the first week. Every demo runs on the device it will ship on, not only in a simulator.
PriceFixed fees for scoped work. Monthly for one of us in your team. We do not bill by the hour, and there are no change orders on a fixed scope.
Regulated workWe sign your agreements and take part in your audits. NDA, MSA, quality agreement, and a remote audit of how we build software. The details for your quality team are on the company page.
StartTell us what you're building. One of us reads it and replies within one working day.
Questions
Do you design the app, build it, or both?+

Both. The people who design your app also build it, from the first sketch to the App Store, so nothing gets lost between the two.

How long does a project take?+

It depends on the product. Sign of Love took nineteen weeks from sketch to the App Store, Yep took three, and a Lightline film takes two. Every fixed scope comes with a schedule.

Do you only work on health apps?+

No. Most of our apps are not medical: games, a music player, private chat, a daily collectible. Health is where we learned to build things that cannot fail quietly, and that habit comes with every project.

Can we start with just an idea?+

Yes. Plenty of projects start as a sentence. Send it, and we will tell you what we would build first and what it would take.

Do you use AI?+

Yes, for the routine work. A person reviews every change and tests it on a real device, generated code gets more review rather than less, and no client code goes to an outside AI model without your written permission.
