JuntoScope is an open-source, anonymous scoping tool developed by OpenForge to facilitate accurate project scoping in software development teams, addressing common challenges like peer pressure and estimation difficulties faced by developers. Built using the Ionic V3 framework, Firebase, and a serverless architecture, the app enhances communication and transparency within teams by offering a seamless experience across platforms. The development process, led by the dev team for the first time, involved innovative design strategies and a feature-oriented file structure, and allowed the team to explore Function as a Service architecture via Firebase. Despite facing challenges like adapting to API changes and handling unexpected marketing requirements, the project was completed in about 383 hours, providing valuable insights into app design and performance without the need for further optimization. JuntoScope is available on both Google Play and the App Store, offering a 10% discount through Teamwork Projects, and the tool's success has prompted discussions of potential integrations with other project management tools like JIRA and Basecamp.
