This app does not attempt to automatically diagnose equipment. Results are for field reference only and should be checked against the equipment nameplate, manufacturer documentation and actual site conditions. Electrical, high-pressure and flammable refrigerant work should be performed by qualified technicians following applicable safety rules.
All data is stored locally on your device. Repair records are not uploaded. The app can be used in airplane mode.
