Insights
Notes from building operational mobile products: how frameworks are actually chosen, what things really cost, and what breaks once an app is in the field rather than on a laptop. Written by the people doing the engineering.
Straight answer
Stable since 2023, officially supported by Google since 2024, Compose for iOS stable since 2025: the timeline, who runs it in production, and when it is worth it for your app. With sources.
Real prices
Published prices from $12,000 to $35,000, why adding iOS adds 35 to 55 percent rather than doubling the bill, the seven things that move a quote, and the costs that sit outside it.
Engineering for the field
The five parts every offline-first app needs, three ways to settle a conflicting edit, and why offline has to be designed in from day one. From apps we have shipped.
Choosing a framework
Flutter shares the interface and draws it itself. Kotlin Multiplatform shares the logic. What that means for cost, native feel and offline work, where each one breaks, and four questions that settle the choice.
Choosing a framework
React Native shares the interface. Kotlin Multiplatform shares the logic. That one sentence explains almost every practical difference between them — cost, hiring, performance, and the kind of bug you will spend your evenings on. Includes four questions that settle the choice in ten minutes.

Bring the product and the constraints. Fifteen minutes is usually enough to tell you what you are actually choosing between — and if the answer is that you do not need us, you will get that straight.
