Just2Test
Documentation and designs for the online research platform and mobile application
About Just2Test and our task
Just2Test is a charitable project of the Centaurus Foundation. Funds raised from the project will be used to support its statutory activities, namely helping animals.
Just2test will be a platform enabling low-cost concept, product, and advertising research worldwide. Just2Test aims to work on two levels: an online platform for commissioning and conducting research for Researchers, and a mobile app for Donors (people who dedicate their time and help animals by participating in research). The name Just2Test was intended to symbolize the key assumptions of the project: Donors spend only 2 minutes a day on the test, and the Researcher receives results within 2 days.
Our responsibilities included providing advisory support for the project (including developing a project business plan, preparing the organizational structure and processes) and developing documentation for the online platform enabling research and a mobile app for Donors.
Our task was to develop comprehensive implementation documentation and graphic designs for the J/ust2test platform using JAVA technology and a mobile application (IOS and Android). Given the project’s global scope, pre-implementation work included addressing language versions of the Donor views and panels for managing the study implementation process.

About the Centaurus Foundation
For 18 years, the Centaurus Foundation has been helping animals in Poland and around the world. To quote the Foundation’s website: “It’s difficult to count how many animals we’ve helped, but after all these years, we’re certain that our work rescuing animals will never end. There will always be an animal somewhere in the world that needs saving. Together, we can save and care for countless lives.”
Analysis of user roles
and system architecture
Together with the eFresh development team, we analyzed user roles, developed functional assumptions, and then translated them into descriptions of key views, user paths, and interface structure. The resulting documentation became the basis for preparing low-fidelity mockups that streamlined the entire system and allowed for a smooth transition to designing the final layouts.
Key roles defined on the platform:
Group A: Time Donors (Mobile App Users) – people supporting the project, donating their time = respondents/participants from many countries.
Group B: Centers: Content Creators – Animal Caregivers showcasing their daily work and sharing their experience caring for animals from around the world.
Group C: Animality Team – screenwriters, video editors, Center Caregivers – all those who process content and operate the platform.
Group D: Animality Managers – the team managing processes on the platform and making key decisions.
During the analysis stage, we devoted considerable attention to developing the system architecture and the principles of communication between its individual modules, taking into account the needs of individual user groups.

List of views and functionalities
The analysis and conceptual work resulted in a userflow document, which described the processes occurring on the platform, user registration and login algorithms, and the operational assumptions for individual views. A document over 600 pages long was created for the video streaming platform, which served as the basis for the design phase and the creation of clickable mockups.
To organize subsequent work, we developed a list of views (unique and complementary) in the Monday software, along with guidelines for designers. With a large number of views, careful planning is essential to avoid gaps and contradictions.
This step created the framework for the entire platform: from registration and login screens, through onboarding and startup views, to returning user scenarios and detailed views of video content and account settings. Each screen had its role and place in the application’s architecture – nothing was left to chance.

Conceptual designs and key views
After completing the UX work, our design team took over the task and prepared the first conceptual designs of the most important views, from the project owner’s perspective. At this stage, we presented sample home views (illustrating, among other things, the researcher’s flow) and preliminary views of the application (time donor).


Development of a design system for the platform
A crucial element of our work, especially in complex projects, is developing a coherent Design System – that is, the principles for creating grids (the arrangement of individual views), designing and using buttons, building sections, and creating illustrations. A well-designed Design System significantly simplifies the development team’s work and helps avoid many errors during the implementation phase.
Researcher mocking up prototypes of web desktop versions
In this phase of development, we transformed previously defined functionalities and views into specific, interactive mockups for the desktop version of the platform from the researcher’s perspective. We focused on ergonomics, intuitive navigation, and clear layout to ensure the best possible user experience and ease of use. We introduced a tutorial module to facilitate study setup for inexperienced users.

Time Donor mobile application
Although the Just2Test mobile app is functionally very similar to the web version for mobile devices, its mockups required a separate approach. This allowed us to better leverage the native app’s features, such as push notifications, quick access from the home screen, and offline functionality. Our mockups focused on user experience and intuitive navigation, adapting the layout and interface elements to the specific needs of Android and iOS mobile devices.
We designed the mobile app views in light and dark modes for user convenience. Graphic design work on the mobile app layouts included creating all necessary views: those essential for the proper functioning and use of the mobile app, as well as auxiliary and additional views.
Extensive J2T team process management panel
A key element of the platform was our extensive ERP system, developed and designed by us, supporting platform processes divided into individual departments: Marketing (promotional activities, mailings, traffic control), Customer Service Office (Customer-Researcher Service), Research Department (creating and publishing new types of research), and IT and accounting.
The developed system enabled intuitive and easy work planning, task control, information exchange between departments, and monitoring, for example, how problems reported by Time Donors and Researchers were resolved.

The process of creating a study for the researcher
When developing the researcher’s process, we emphasized making it as easy to configure as possible and requiring no specialized research knowledge. Subsequent steps included selecting the characteristics of the study group and geographic scope, and constructing the survey. We offered a wide database of sample, ready-made surveys tailored to various industries, as well as a flexible configurator. The researcher prepared the service/product description in the form of a video, for which a tutorial was also created. For professional clients (large companies), we created a module for survey preparation by a J2T consultant.

The Time Donor Participation Process
The time donation was based on the donor’s use of their “free time,” such as on the bus, tram, or at lunch. When joining the project, the donor specified their preferences (donating on specific days of the week or simply on one selected day). J2T prepared a video and a survey for the selected time, taking no more than 5 minutes per day. Immediately after completing the survey, the donor received a video message and a thank-you note from the specific animal caregiver who benefited from their donation.

Platform Results Reporting Module
An important module we developed for J2T is an advanced reporting system divided into several views: the General Report (key platform results, available to the J2T team), and the Management Report (focused on the platform’s financial results). Obtaining reliable results in these reports required designing detailed algorithms for downloading data from the platform live.

Desktop implementation of the J2T platform
The implementation work took 12 months and was divided into 24 sprints (each sprint was 10 business days), including: 8 business days for developers, 4 hours for QA testing, and 4 hours for client-side testing. Each sprint included 1 day for improvements; if the project was completed faster, we would start another sprint.
Management and progress control:
- In the Monday.com system, we maintained a board accessible to the client and the team, where we monitored project progress.
- The client reviewed a given sprint and provided feedback in sprint comments.
- Sprint closure, acceptance protocol, and work settlement were all handled entirely remotely.
We conducted the testing based on the description of the so-called business test scenarios provided by the client

Desktop implementation of the J2T mobile application
An essential element of the entire project was the creation of a mobile app where donors could support animals by devoting just two minutes a day. The platform’s goal was to attract large groups of donors from various countries to ensure the credibility of the research being conducted.
