Apps peoplewant to use.
Guavalin is a small studio designing and engineering iOS products that earn a place on the home screen. Made carefully, shipped patiently — one app at a time.
Approach
Software,
held to a higher standard.
Most apps feel like they were built by committee — for the quarterly review, not the person holding the phone. We're trying to do the opposite. Fewer products, more attention. Sharper taste, smaller surface area.
- 01
Useful first.
Every product starts with a real problem worth solving — not a feature, not a trend. If it isn't useful on day one, we don't ship it.
- 02
Made with care.
Type, motion, copy, latency, empty states. The thousand small decisions that separate software you tolerate from software you reach for.
- 03
Owned by the maker.
Independent, self-funded, no committees. Decisions are made by the people doing the work. That's why the work is good.
Selected Work — 2024 to 2026
Four products,
one philosophy.
Each project below was designed, engineered, and shipped by the same hands — no agency, no outsourcing. Some are live, some are still becoming.

Sue the Sous Chef
Cooking, finally simplified.

Services
Selectively
available for outside work.
Most of our time goes into our own products. The rest goes into a small number of consulting engagements with teams we admire. If that's you — let's talk.
- I
Product engineering
End-to-end iOS and web product builds. Native Swift / SwiftUI, React Native, and full-stack on TypeScript. From zero to App Store, or from prototype to production.
- II
Design partnership
Interface design, motion, and brand systems. Embedded with your team — or steering the ship — for a sprint, a launch, or a quarter.
- III
AI integration
Pragmatic, production-grade LLM features. RAG, agents, evals, cost optimization. The unsexy parts that make AI products actually work.
