Offline-first bespoke data collection apps from Open Data Ensemble

Republished from GitHub / F-Droid by the Zapstore main account.

Formulus is the mobile data collection client of the Open Data Ensemble (ODE) platform. It allows organizations, research teams, and public sector institutions to build their own bespoke data collection applications based on structured forms defined using the JSONForms specification. Forms and application logic are defined externally, meaning the same Formulus app can host many different data collection projects without requiring app updates. Key features include: • Flexible form-based data collection using JSONForms • Offline-first operation for use in the field • Secure bi-directional synchronization with an ODE Synkronus server • Support for complex data structures and validation • Designed for long-term maintainability and open standards Formulus is particularly suited for environments where reliable data collection is needed under challenging conditions, such as: • field research • public health surveillance • environmental monitoring • humanitarian and development projects • decentralized data collection initiatives The app requires access to an ODE Synkronus server for synchronization and project management. Organizations typically run their own Synkronus server to host forms, manage users, and collect submitted data. If you do not yet have access to a Synkronus server but would like to explore the application, a public demonstration environment may be available. See the project website for details. Formulus is part of the Open Data Ensemble ecosystem, an open-source initiative focused on building interoperable tools for decentralized, standards-based data collection.

  • Oct 1, 2026 1.4.0
    ## ODE v1.4.0 This release brings two major additions to ODE, alongside a broad set of improvements across Formulus, FormPlayer, ODE Desktop, documentation, security, and developer tooling. ### Multiple profiles in Formulus Formulus can now manage **multiple profiles on the same device**, each with its own custom app and Synkronus connection. This makes it much easier to use one device across different projects, studies, deployments, or environments without repeatedly reconfiguring Formulus. Profiles can be created and switched directly from within the app.

    ### First-class support for AI agents in ODE Desktop ODE Desktop now exposes ODE directly to **AI agents** through two complementary interfaces: - a rich command-line interface for working with ODE data and functionality - a local **MCP server**, allowing MCP-compatible agents and development environments to interact with ODE natively This is an important first step toward making ODE not just a tool people use directly, but also a platform that AI-assisted workflows can safely build upon. You can control what your local AI agents have access to from within the profile settings in ODE Desktop: <img width="1101" height="292" alt="image" src="https://github.com/user-attachments/assets/f9202661-497f-4af0-adb9-ae2d174aaf02" /> ### And, most importantly: the community This release also includes contributions from a growing number of new contributors across Formulus, FormPlayer, ODE Desktop, documentation, testing, CI and release tooling. A huge thank you to everyone who contributed code, testing, documentation, reviews, ideas, and time. **The people contributing to ODE are what make the community worth our combined effort.** Welcome to all our new contributors, and thank you for helping make ODE better ❤️ ##
