Researchers in Ecuador developed an app called Mikuy that scored 83.75 out of 100 for ease of use and received high acceptability ratings (4.60+ out of 5) in testing with 99 community members. According to research reviewed by Gram, this smartphone tool helps community health workers prevent childhood malnutrition by working offline, supporting Spanish and Kichwa languages, and tracking home visits in rural mountain areas where internet is unreliable. While the app shows strong promise in design and usability, studies proving it actually reduces malnutrition in children are still needed.
Researchers in Ecuador created a smartphone app called Mikuy to help community health workers prevent malnutrition in young children. The app was designed with input from 99 people, including pregnant women, mothers, and health workers in rural mountain communities. The tool works offline, supports both Spanish and the local Kichwa language, and helps health workers track home visits and give families nutrition advice during a baby’s first 1000 days of life. Testing showed the app was easy to use and people liked it, making it a practical solution for areas with limited internet access.
Key Statistics
A 2026 user-centered design study of 99 participants in rural Ecuador found that the Mikuy mHealth app scored 83.75 on the System Usability Scale, indicating excellent ease of use for community health workers and mothers.
According to research reviewed by Gram, the Mikuy app achieved acceptability scores of 4.60 or higher out of 5 across multiple measures, with participants rating it as useful for supporting families during the first 1000 days of a child’s life.
A 2026 study of 99 rural Ecuadorian participants identified offline accessibility as the most critical feature for mHealth tools, with the Mikuy app designed to function without internet connection in areas with limited connectivity.
Research from 2026 involving 84 mothers and 15 community health workers in Ecuador showed that language switching between Spanish and Kichwa was essential rather than optional for reaching indigenous families with nutrition education.
The Quick Take
- What they studied: Can a smartphone app help community health workers prevent malnutrition in children living in rural Ecuador?
- Who participated: 99 people from rural mountain communities in Ecuador: 84 pregnant women or mothers and 15 community health workers who provide basic medical care in their villages.
- Key finding: The app, called Mikuy, scored 83.75 out of 100 for ease of use and received high marks for acceptability, meaning people found it helpful and wanted to use it.
- What it means for you: If you live in a rural area with limited internet, this app could help health workers give you better nutrition advice for your baby during the critical first 1000 days of life. However, the app is still new and needs to be tested in real-world use to prove it actually prevents malnutrition.
The Research Details
Researchers used a ‘user-centered design’ approach, which means they asked the actual people who would use the app what they needed. The study happened in three stages over time. First, the team talked to pregnant women, mothers, and health workers to understand their challenges and what would help them. Second, they designed the app’s content and how it looks on the screen based on what people told them. Third, they tested the app with real users to see if it was easy to use and if people liked it.
The researchers used two main ways to gather information. Qualitative methods included focus groups (small group discussions), design workshops where people helped create the app, one-on-one sessions where users talked through what they were doing, and watching people use the app. Quantitative methods meant giving people surveys with scoring systems to measure how easy the app was to use (called the SUS score) and whether people thought it was useful (called the TAM score).
This approach is important because apps designed in offices without talking to real users often fail in developing countries where internet is spotty and people speak different languages. By involving the actual community health workers and mothers, the researchers made sure Mikuy would actually work in real life.
Community health workers in rural Ecuador are the main connection between families and healthcare, but they struggle with paperwork, tracking visits, and remembering all the nutrition information they need to share. A well-designed app could reduce their workload and help them focus on teaching families. This study matters because it shows how to create technology that actually fits into people’s lives instead of forcing people to change how they work.
This study is reliable because it involved the people who would actually use the app from the very beginning. The researchers tested the app multiple times and made changes based on feedback. The high usability score (83.75 out of 100) is a strong indicator that the app is genuinely easy to use. However, this study only tested whether the app works well, it didn’t yet prove that using it actually reduces malnutrition in children. That would require a larger study following families over time.
What the Results Show
The app Mikuy scored 83.75 on the System Usability Scale (SUS), which is considered ’excellent’ for ease of use. This means the 99 participants found the app straightforward to navigate and understand. On acceptability measures, the app scored 4.60 or higher out of 5, indicating that health workers and mothers believed the app would be useful for their work and lives.
During testing, participants identified several critical features that made the app work in their context. The most important was offline accessibility, the app works even when there’s no internet connection, which is essential in rural mountain areas. The app also switches between Spanish and Kichwa (the local indigenous language), making it accessible to all community members. Other key features included the ability to map household locations and a system to track when health workers visit families.
When researchers watched people use the app and listened to their feedback, they made improvements to how the app looks, how people move through it, and the language used. These changes came directly from what real users said was confusing or difficult. The final version reflected these real-world adjustments.
Beyond the main usability scores, the research revealed that connectivity was the biggest barrier to using health technology in these communities. Participants emphasized that any tool must work without constant internet. The study also showed that cultural appropriateness matters enormously, having the app in Kichwa wasn’t just nice to have, it was essential for reaching indigenous families. Health workers noted that a system for tracking home visits would help them remember which families they’d visited and what advice they’d given.
Previous research has shown that mHealth tools often fail in developing countries because they’re designed without input from the communities that will use them. Gram Research analysis shows that this study follows best practices by involving users from the start. Most health apps designed in wealthy countries assume reliable internet and don’t account for language diversity. Mikuy addresses both of these gaps, making it more likely to succeed than typical health apps tested in similar settings.
This study tested whether the app was easy to use and whether people liked it, but it didn’t yet prove that using Mikuy actually prevents malnutrition in children. That would require following families over months or years to see if their children grow better. The study involved only 99 people in one region of Ecuador, so results may not apply to other countries or even other parts of Ecuador. The app was tested in controlled situations, not in the messy reality of daily health work. Finally, the study didn’t measure whether health workers would actually keep using the app after the initial excitement wore off.
The Bottom Line
If you’re a health organization working in rural areas with limited internet, Mikuy shows promise as a tool to help health workers support families during pregnancy and a baby’s first 1000 days. The app’s design specifically addresses real challenges in developing countries. However, wait for larger studies that prove the app actually reduces malnutrition before making it a centerpiece of your program. Use it as a support tool alongside existing health services, not a replacement. Confidence level: Moderate, the app works well in testing, but real-world effectiveness still needs proof.
Community health workers in rural Ecuador and similar areas should care about this research. Pregnant women and mothers in these communities could benefit from better support. Health organizations and governments working to reduce child malnutrition should pay attention. People in other developing countries with similar challenges (limited internet, multiple languages, rural communities) might adapt this approach. This research is less relevant for wealthy urban areas with reliable internet and established health systems.
If a health program implemented Mikuy today, health workers could start using it immediately since it works offline. However, it would take 6-12 months to see whether it actually improves nutrition outcomes in children. Real benefits in reducing malnutrition would likely take 1-2 years to measure, since children’s growth is a slow process.
