# Iconic Product Comparison ## Docs - [Appearance, design, and theme](https://product-comparison-docs.geticonicapps.com/help-center/appearance-design-and-theme.md): Iconic Product Comparison keeps two design systems: one for specification tables and one for comparison tables. Use Settings, open each Customize editor, tune layout and colors, then use Add to your theme to return to the theme editor. - [Comparison tables](https://product-comparison-docs.geticonicapps.com/help-center/comparison-tables.md): Compare with is the main way to get the most relevant comparisons. If it is empty, the block can still use Shopify-related products. You need a linked specification table with Comparable attributes. Adjust the maximum number of products to show up to twenty. - [Getting started](https://product-comparison-docs.geticonicapps.com/help-center/getting-started.md): Install the app, enable the Iconic Product Comparison app embed, add the specification and comparison blocks in your theme, and follow the dashboard setup guide. Use Settings to open the theme editor when you are ready. - [Plans and billing](https://product-comparison-docs.geticonicapps.com/help-center/plans-and-billing.md): Iconic Product Comparison is free to use today. Open Pricing in the app to view your plan on the billing page. If billing is still linking for your shop, finish setup from the home screen first. - [Products and assignment](https://product-comparison-docs.geticonicapps.com/help-center/products-and-assignment.md): Search products, see which specification table applies, manage Compare with up to twenty products, and learn why a manual table choice on a product overrides automatic assignment rules from your tables. - [Specification tables](https://product-comparison-docs.geticonicapps.com/help-center/specification-tables.md): Learn how specification tables work in Iconic Product Comparison: create a table, set assignment conditions, organize groups and attributes, upload optional icons, and keep your storefront data clear and consistent. - [Storefront experience for shoppers](https://product-comparison-docs.geticonicapps.com/help-center/storefront-experience-for-shoppers.md): Shoppers see grouped specification rows, optional long-table controls, and a comparison grid with column headers and actions you configure. Options like hiding matching values help people focus on differences. - [Troubleshooting](https://product-comparison-docs.geticonicapps.com/help-center/troubleshooting.md): Tables missing on the storefront usually trace back to the app embed, theme blocks, product assignment, or missing Comparable attributes. Compare with is the main way to control comparisons; related products can still appear when Compare with is empty.
