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. TestDue Pro is an auto-renewing subscription: $12.99/month or $79.99/year (with a 7-day free trial on the annual plan). Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Terms of Use: https://jmarrr.github.io/dueflow/terms.html Privacy Policy: https://jmarrr.github.io/dueflow/privacy.html
