Build Notes

What I’m learning while shipping

Technical write-ups, product decisions, distribution experiments, and honest field notes from building iPhone apps, SaaS products, and AI tools.

Latest

New from the build log

Long-form notes with enough context, evidence, and technical detail to stay useful after the timeline moves on.

Writing themes

What I write about

These are the recurring themes behind Build Notes. As the library grows, themes with published articles will become browsable collections.

Engineering

iOS development

MVP boundaries, implementation tradeoffs, App Store details, bugs, and the unglamorous work around the core feature.

Agent-native products

AI & MCP

Tool contracts, permissions, reliable outputs, agent workflows, and what changes when a dashboard is no longer the primary interface.

Distribution

ASO & Apple Ads

Keyword assumptions, App Store conversion, small-budget acquisition tests, and what happens after the traffic arrives.

Business

SaaS experiments

Pricing hypotheses, narrow customer definitions, manual validation, operating costs, and criteria for continuing or stopping.

Shipping

Launches & postmortems

What shipped, what was deliberately cut, what users noticed, and what I would do differently on the next release.

In public

Numbers & lessons

Honest progress before the metrics look impressive: results, failed bets, changed minds, and the next measurable experiment.

Published notes appear above. Topic navigation will activate as each collection grows.

KS

The publishing approach

Experience first, article second

Short observations usually appear on X while an experiment is still running. Build Notes are the durable version: enough context, evidence, code, screenshots, and reflection to be useful after the timeline moves on.

The library will grow with the products. Until each long-form note is ready, follow @kovsmakesapps for the work in progress.
