We make software

we're proud of

A tiny studio with unreasonable standards. We make our own apps, design brands, and build software for people who notice the difference.

We are nerds.

We build for awe, not engagement. For moments of clarity, not hours of scrolling. We want our apps to make your day a little better.

We believe your data is yours. It stays on your device, not our servers. We don't track you. We don't sell you. We don't even want to know who you are. We just want to make something useful for you.

We build software that lasts. No subscriptions that hold your data hostage. No growth hacks that prioritize metrics over people.

We optimize for stories, not profit. For the person who tells a friend, not the metric that impresses investors. We'd rather have a thousand people who love what we make than a million who feel trapped by it.

We're small on purpose. No investors. No growth targets. No trend chasing. Just two friends building software we'd want to use. That's it. That's the company.

Services

From idea to App Store

Strategy, design, and development from people who've done it themselves, without the agency overhead.

Strategy Most first versions try to do too much. We help you find the idea inside the idea, the version that ships fast, teaches you something, and gives you a foundation to grow from.

Design We design software that works, then make it beautiful. Fast cycles, constant testing, no pixel-pushing for its own sake. The goal is software people understand the moment they open it.

Branding Your product needs a face before it needs a marketing team. We create identities that are clear, simple, and built to last longer than your first pivot.

Development From Figma to Xcode, same hands. We implement our own designs in native Swift, no separate dev team reinterpreting your product. The follow-through is the point.

Websites Your site should feel like your product. We design and build marketing sites, landing pages, and docs that match your software: fast, clear, and conversion-ready.

AI & Machine Learning We build AI that actually helps. Our app Whistle is an AI fitness agent, it plans, adapts, and coaches. We bring the same approach to client projects: ML that solves real problems, not demos.

Technologies

What powers our apps

We'd rather own our stack than depend on someone else's. When something matters, we build it ourselves. Full control, no surprises, no waiting on someone else's roadmap.

IntelligenceKit The agent layer behind our AI features. Orchestrates models, handles memory, powers interactions from subtle prompts to complex autonomous workflows. Built for real products, not demos.

FeatherKit Our design system. Components, patterns, and primitives that make apps feel consistent from day one. Born from our own products, refined with every release.

RevenueKit Subscriptions, paywalls, referrals. We built this so we'd never have to think about StoreKit edge cases again.

InsightsKit Anonymous, privacy-first tracking that tells us what's working, without harvesting user data. A/B tests included.

FitKit The health intelligence behind Peaks and Whistle. Sleep stages, training load, recovery metrics, circadian rhythm, all processed on-device, all ready to use.

The messy middle

Building software is full of wrong turns and hard calls. Here's what that actually looks like.
