Zero
Shortform email. Swipe-first triage with AI-extracted action items. Built solo, internal beta — the trust ceiling kept it from market.
WHAT IT WAS
Shortform email · swipe-first triage
Zero is a shortform email app. Swipe-first triage, AI-extracted action items and deadlines, fast inbox processing. Built solo, shipped cross-platform to the App Store.
In parallel, I was building Heirloom — a recipe app to solve a personal frustration I called cooking math. Both apps were live for a stretch. After several rounds of feedback, Zero got sunset and Heirloom went all-in.

The work that came before the post-mortem
Two surfaces from the build, in order: an intent + action explorer that validated the classification space before the app, and the swipe-first triage build it grew into. iOS internal beta, then I pulled it — never reached the App Store.
POST-MORTEM · TRUST CEILING
Why Zero didn't ship
The decision came down to three questions:
- What are the consequences if the app fails?
- How much trust does the domain require before users will adopt it?
- Can a new product reach that bar?
Email failed all three. If an AI email tool misses a bill payment notification, someone could lose their mortgage. High stakes raise the trust ceiling, and a high trust ceiling means near-perfect reliability — a bar a solo studio can’t credibly hit.
So Heirloom got the green light. Recipes have a different equation: two testable pieces (ingredients and instructions), a low trust ceiling, and a personal connection that justified the build.
