AuditPro
A TightnessPro app by Audit-Pro Ltd
TightnessPro guides qualified gas engineers through structured tightness testing, strength testing, direct purge and installation-volume workflows — on domestic, commercial and industrial installations alike — then produces clean, branded PDF records with captured signatures, all from your phone or tablet.
Step through a structured tightness testing workflow with guided routing and a clear pass/fail outcome to record against the job. On commercial work the test duration and allowable movement are calculated for the installation, and strength testing is included where the job calls for it.
Run a direct purge workflow with the calculations handled for you, capturing the details needed for a complete record.
Calculate installation volume from pipe sections and meter volume, with the pipe sizes and meters that suit the installation type, ready to feed into your test and reporting.
Choose the installation type at the start and the app follows the right procedure for it — the test parameters, the pass criteria and the paperwork all change with the size of the job.
Natural gas in a home. Pipework up to 28 mm bore, operating pressure up to 21 mbar, standard domestic meter.
Natural gas, installation volume up to 1 m³, pipework up to 150 mm bore and operating pressure up to 40 mbar. Test duration and allowable movement calculated from the volume and your gauge.
Any supported gas, larger volumes, pipework above 150 mm bore or pressures up to 16 bar. Adds pipework area assessment, leak-rate criteria, strength testing with its safety controls, and routes for plastic pipework and higher-pressure installations.
Clear, step-by-step screens that work without a signal on site. A short offline grace period keeps you working if connectivity drops.
Apply your company name, logo, and operative details so every exported report carries your branding.
Collect the engineer signature, and an optional gas-user signature, directly on the device before export.
Your company details, job data, and reports are stored only on your device. We do not run a server that collects your data.
Generate a PDF and open, print, or share it with your own tools. Files are named by date and site for tidy record-keeping.
A responsive layout designed for everyday use on the devices you already carry to the job.
Each tightness test and purge can be exported as a structured PDF record that includes your company details, the site address, the captured signatures, and the relevant test details — ready to hand to the customer or keep for your files.
Commercial records show the working, not just the answer. A corrected reading, a governing criterion or an allowable limit appears alongside what it was derived from, so anyone reading the record later can check it rather than take it on trust.
TightnessPro is a calculation and reporting aid for qualified gas engineers. It supports, but does not replace, your professional judgement, applicable gas safety requirements, manufacturer instructions, and your own working procedures. You remain responsible for verifying results and for the safety and compliance of any work.
TightnessPro is available on an annual subscription with a 7-day free trial for new subscribers. Billing is handled by the App Store or Google Play, and you can manage or cancel any time in your store account settings.
