## What is TestDue?

TestDue is the offline test ticket for solo backflow testers.

Open an assembly, see next due, log this test on a gauge card. Fields follow RP, DC, PVB and SVB. Overdue tickets are the pipeline. Share the ticket face. Fully offline — no account, no server, not the city's filing portal.

Built for the book:
• One test ticket with a huge next-due date
• Gauge card: relief, check 1, check 2
• OVERDUE on the same ticket
• Share the ticket face (Pro clean)
• Search and filter across the book

PRIVACY
TestDue has no account and no server. Assembly data never leaves your device.

TESTDUE PRO
Free: 40 assemblies with the full ticket and gauge. Pro: unlimited assemblies, clean shared tickets, full test history.

Log only — not a filed test report.
