Pipfitter (iOS field tool)

Offline iPhone app for pipe fitters: Stabila-style level with REF calibrate, searchable fitting take-offs (threaded / socket weld / butt weld), and Run Builder cut math.

Body

Pipfitter — product ecosystem entry

Status: M1 workspace bootstrap (2026-07-03) Platform: iOS 17+ (Xcode on MacBook-Air) Authority: Local repo /root/pipfitter; Explorer catalog is source of truth for ops memory.

Vision

Pipfitter is an offline iPhone field tool that combines:

  1. Level — spirit level with reference calibrate (REF) and tolerance-band audio lock
  2. Handbook — offline searchable take-offs by joint type (threaded, socket weld, butt weld)
  3. Run Builder — CTC in → cut length + allowance band out

Positioning: PipeFit Pro math depth plus pocket Stabila level UX. Primary wedge vs PipeFit Pro: no level sensor.

Audience

  • Journeyman pipefitters, plumber-steamfitters, apprentices, maintenance millwrights, HVAC rough-in

Monetization (planned)

  • Free tier: level + limited handbook rows + basic offset
  • Pro: $6.99 lifetime IAP (no subscription)
  • Fixed cost: ~$99/yr Apple Developer only; break-even ~17 sales
