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 inputs, imported rows, saved work records, comparison settings, and export history, plus images you select and optional site coordinates you deliberately attach remain in local app storage.
What are the limits?
Community metrics depend on sampling design and identification quality. Follow the protocol, taxonomy, permits, regional references, and agency or research requirements for the project.
