GasTest Log
Read full descriptionHide full description
Run the gas piping pressure test and hand the inspector a certificate. GasTest Log times the code-required hold, captures a start and end gauge photo as proof, and exports a one-page, code-cited PASS/FAIL report — right from your phone. It does NOT measure pressure. Your gauge does that. GasTest Log times the hold, documents what you read, and turns it into a clean certificate — so a missed inspector visit no longer means a re-trip. HOW IT WORKS • Pick a code preset: single-family 3 psi / 10 min, elevated 2-lb, commercial (IFGC — ½ hour per 500 ft³ of pipe), UPC 10 psi / 15 min, UPC welded 60 psi / 30 min, or custom. • Photograph the gauge to start a wall-clock countdown with haptic checkpoints — keep working, it holds time even with the screen off. • Photograph the gauge again at the end. Enter your start and end readings. • You attest PASS or FAIL. Export the certificate. THE CERTIFICATE • Date, address, permit, technician, license, and company. • Gas type, medium, required pressure and hold, your actual hold time, and start/end readings. • Side-by-side start and end gauge photos as tamper-evident proof. • The governing code citation (IFGC 2021 / IRC / UPC) and the AHJ acceptance line. BUILT FOR THE TRADE • Works fully offline. No account, no sign-in, no cloud. • Camera + optional location only. Your photos and readings never leave your phone. • No Bluetooth manometer required — use the mechanical gauge already on the pipe. A TOOL, NOT A CODE AUTHORITY Test pressures and hold durations follow the model codes (IFGC/IRC, or the UPC where adopted) — local amendments vary, so always confirm with your AHJ. The app does not measure pressure or decide pass/fail; you read the gauge and attest the result. PRO A one-time unlock — no subscription. Export the certificate PDF, add your company branding, and keep a saved history of every test. No ads. No tracking. No account. Time it. Photo it. Prove it.

Verdict
The clearest difference is in-app purchases: OneControl Auto at none against GasTest Log's 1. OneControl Auto also leads on update cadence (every 5 weeks vs every 3 months) and device support (3 vs 1). On price and ads there is nothing between them.
