Built for LeakHunter devices, the app makes it easy to run professional airtightness tests to the ISO 9972 standard. Follow the test in real time, watch live pressure and flow values, and generate precise reports on the spot. Perfect for contractors, energy consultants and inspectors who need reliable results immediately.
