Compute the 1.5x design-pressure basis, stress-ratio correction, gauge range sanity, and lowest-component cap from values the crew keys off the approved package.

Built For The Manifold
Compare held pressure against the expected temperature-driven band so a cooling line does not send the crew chasing a phantom leak.
Capture readings, hold timing, gauge calibration, optional photos, witness signature, and local PDF/CSV exports.
Field-aid limits
HydroTest DC does not measure pressure, measure temperature, approve a system for service, design a pneumatic hazard plan, or replace the approved test package. The calibrated gauge or recorder is the instrument of record, and the witness or project authority decides acceptance.
FAQ
Does it qualify or approve the test? No. It records readings and computes field-aid math from user-keyed values. Your approved test package and witness remain the authority.
Does it work offline? Yes. Records, signatures, photo captions, timers, thermal verdicts, and exports are local. Purchase and restore require RevenueCat-backed Google Play.
What is Pro? Two sections are free. Pro is a $9.99 one-time unlock for the full local ledger and export workflow.
