GaugeGate DC is a field tool for duct layout, build cards, leakage targets, and balance records. It is not the SMACNA standard, not engineering of record, and not an AHJ decision.
Verify every output with a competent person against the project spec, the governing standard and edition, and the AHJ. The third-party leakage test is the gate. GaugeGate DC does not declare a job complete.
The app stores run cards, balance entries, preferences, and export drafts on the device. Exports are field records created by the user and shared only when the user chooses an Android share target.
Pro is a one-time lifetime unlock for saved-card capacity, TAB persistence, and PDF, CSV, and ZIP export. On-screen calculations stay real and unblurred on the free tier.
