Does it work offline?
Yes — completely. There is no login and no internet requirement. The AQL calculator, defect log and PDF reports all work with no signal.
Which standard does the calculator use?
ANSI/ASQ Z1.4 (ISO 2859-1) single-sampling, normal-inspection tables. Enter a lot size, inspection level and AQL to get the sample-size code letter, sample size (n) and the Accept/Reject (Ac/Re) numbers.
Where is my data stored?
Entirely on your device. Nothing is uploaded to any server. See our Privacy Policy for details.
How do I share an inspection report?
Open the inspection and export it as a PDF, then use your device's share sheet to send it by email or messaging app. You choose where it goes.
How do I back up my inspections?
Export the reports you want to keep as PDFs and store them wherever you like. Because data stays on-device, removing the app removes its data.
