Documentation
Open documentation about site features and product data.
Source code and data
The site's README covers local development, content, the audiogram flow, the device catalogue and tests. The product catalogue is available as JSON. The sitemap lists published pages.
About product details
The catalogue contains manufacturer, model, category, technical features, a source link and date of verification. Null in JSON means the detail is unverified or unspecified; it does not mean no. The audiogram is not used to rank devices.
