Common Questions
Does the app need an account, subscription, or in-app purchase?
No. It is a one-time paid download with no account, advertising, analytics, subscription, or in-app purchase.
Does it work offline?
Yes. Core features and bundled material work without a developer-operated service.
Where is my information stored?
Your editable workspaces, parameter values, imported records, comparison settings, notes, and export history remain in local app storage.
What are the limits?
Measurement and planning aid. Verify regulated broadcast or mastering deliverables with calibrated, validated tools and the applicable delivery specification.
