Construction-plan complexity reshaped into one field board.
An iPhone-first workspace that keeps a complete construction plan set intact while letting a person assemble the drawings, checks, and notes needed for the work in front of them.
05 / proof surface
01 / The challenge
Start with the operating tension.
Large construction PDFs are authoritative but awkward at the point of work. The product needed to create a focused field view without corrupting the source or pretending to be a full project-management platform.
02 / The approach
Shape the system around the constraint.
FieldStack uses field-informed problem framing and a deliberately bounded product contract: import the source, preserve it, create focused boards, and store checks and notes in a separate local layer.
03 / The working system
What exists.
- 01
Complete plan-set reading, navigation, and search
- 02
Focused boards assembled from selected drawings
- 03
Structured checks, notes, status, and handoff state
- 04
Local-first storage with source and overlay separation
Capabilities demonstrated
Transferable judgment, shown in context.
04 / What the evidence supports
Proof on the page.
- FieldStack 1.0 is available on the App Store for iPhone.
- A substantial iPhone codebase, tests, product documentation, and release records exist.
- The public product page reflects the current bounded product contract.
- The architecture separates imported source PDFs from app-owned field overlays.
Claim boundary
Where the evidence stops.
- Company-wide distribution remains owner-reported and is not claimed here.
- No recipient count, adoption, time saved, or business outcome is asserted.
- Early App Store units are owner-observed; retention and field outcomes are not yet measured.
