Learning Journey
Learning Journey
Our team learned the fundamentals of mobile development using MIT App Inventor. A major technical challenge was synchronizing our health unit list with the correct Google Maps URLs. We overcame this by studying list indexes and configuring the Activity Starter with Android Intents to automate navigation. Non-technically, we faced the challenge of keeping the design intuitive. We learned to prioritize a simple, accessible interface over complex visual features. By collaborating and testing, we successfully connected TinyDB for logins and external maps, turning our idea into a functional prototype.
Information Legitimacy Description
To ensure our project’s information was legitimate, we combined direct user research with official data validation. First, we conducted surveys and interviews with the community to understand their real difficulties in locating regional healthcare units. This primary research validated the actual problem and user needs. Then, to guarantee the accuracy of the data within the app, we cross-referenced the health unit locations and names with official municipal health records and verified the coordinates on Google Maps. By combining community feedback with official public sources, we ensured our app provides reliable information.

When developing our app, ethics were central to our approach, prioritizing user privacy, safety, and accessibility. First, regarding data privacy, we utilized TinyDB for local storage, ensuring that login credentials remain on the user's device rather than being collected or exploited on external servers. Second, we prioritized accuracy. During our research with 24 community members, we realized that providing incorrect healthcare locations could have serious consequences. Therefore, we ethically committed to cross-referencing all health unit data with official municipal records and Google Maps to prevent misinformation. Finally, we focused on inclusivity. Knowing that 95.8% of our respondents struggled to find medical help, we designed a highly simplified, clutter-free interface. This ensures that users of all technical skill levels, especially vulnerable populations seeking urgent care, can navigate the app without technological barriers.
