D3.5 – VeriFish Prototype of the web & mobile App - final release

The VeriFish app represents a key milestone in making seafood sustainability information accessible to European consumers and stakeholders. This document presents a concise description of the final release of the VeriFish web and mobile application D3.5 Prototype of the web app - final release - DEM, marking the completion of the prototype development cycle initiated with D3.2 VeriFish web app requirements & specification document and D3.4 Prototype of the web app - initial release. The application is now publicly available as a web-app at the address https://app.verifish.info/ and is being published on both the Apple App Store and Google Play Store during May 2026.

The final release builds on all core functionalities developed in the initial release  -species factsheets, multilingual search, sustainability indicators, nutritional data, and provenance information-  and introduces a significant architectural upgrade: the migration of the backend data layer from Firebase/Firestore to Supabase. This change was driven by the need for more expressive and flexible query capabilities, enabling richer data filtering, more efficient joins across species data, and better support for structured analytics that the application's growing data model required. This release also addresses the feedback received during the two feedback gathering sessions organised on 20 November 2025 during the VeriFish Workshop at the Catch Welfare Platform Conference 2025, and on 11 March 2026 in conjunction with the VeriFish final event (both sessions are further reported in D3.6 Communication, stakeholder engagement final report)

In addition, the final release introduces major enhancements to usability and performance, including a fully redesigned user interface based on expert feedback, simplified navigation, integration of new data sources such as the dataset from EU’s STECF, and an expanded set of socio-economic, environmental, and aquaculture indicators’ data.
