About
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.
