A new pilot study has found that a mobile application designed for young adults in the Philippines can significantly improve mental well-being and positive mood. The app, called LUNA, was created to address the country’s growing need for accessible mental health tools, particularly among those facing barriers to professional support. The findings were published in Psychreg Journal of Psychology.
LUNA combines three key features: mood tracking, mindfulness exercises, and journaling. Over a four-week period, 30 participants aged between 20 and 30 used the app daily. They were encouraged to record their mood, complete a short mindfulness activity, and write journal entries. By the end of the trial, results showed a moderate but statistically significant improvement in both mental well-being and positive affect, while negative mood levels remained largely unchanged.
The study was conducted in response to ongoing mental health challenges that worsened after the Covid pandemic. Filipino young adults have reported heightened stress, anxiety, and feelings of isolation, often compounded by cultural stigma and a shortage of mental health professionals. By using a smartphone-based approach, researchers aimed to provide a low-cost, scalable alternative that could reach users in both urban and rural areas.
Lyen Krenz Yap, a PhD researcher at Ulster University, said: “During the pandemic that, as we all know, led to a mental health catastrophe across the globe, one of my main sources of comfort was the mental health chatbot called Wysa. For my master’s degree, I was interested in the potential of mental health apps to improve mental well-being. After emailing dozens of mental health app companies publicly available for download, they either did not respond, admitted that their app was not evidence-based, or had conducted corporate-funded studies. I knew that I had to set out on this research endeavour: do mental health apps actually work?”
Feedback from participants revealed that the app’s simplicity and offline accessibility were major strengths. Users valued the uncluttered interface, absence of advertisements, and straightforward navigation. Many highlighted the journaling feature as a safe space for self-expression and emotional reflection, helping them recognise patterns in their thoughts and feelings. Mindfulness exercises were reported to bring calm and reduce stress, though some found them uncomfortable or difficult to engage with.
Reflecting on the study’s outcomes, Yap noted, “Three key takeaways from the LUNA study would be: the research protocol, which has implications for future researchers through the I-P-O-F Model of Application Development; LUNA being one of the first attempts at an evidence-based digital mental health intervention for Filipinos that has proven significant pilot effects on affect and well-being; and the finding that interrelated factors affect our relationship with DMHIs, with implications for policy and investment in Philippine mental healthcare.”
There were also calls for improvements. Participants wanted more flexibility in mood tracking, such as the ability to log multiple emotions in a day and edit previous entries. Some requested greater personalisation, including custom journal prompts, voice notes, and the option to adjust the app’s design. Technical suggestions included adding auto-save to journaling, downloadable mindfulness videos, and a calendar view to track progress over longer periods.
The app’s development followed a collaborative process involving a primary investigator, a freelance artist, and a developer. The team faced constraints that limited certain features but used iterative testing to refine usability before the pilot launch. Researchers noted that the most effective aspect of LUNA was not any single tool, but the combination of its three components working together.
Looking ahead, Yap shared, “I am about to start my second year of pursuing my PhD funded by Ulster University’s Research Scholarship. Here, findings from LUNA are helping inform research that takes a closer look at our relationship and engagement with DMHIs. I am grateful for the chance to work with Dr Edel Ennis and Professor Maurice Mulvenna, two of the biggest names making strides in DMHI research across the UK and EU. My research team has just recently published a research protocol. LUNA has come a long way, and I owe it all to my brilliant participants that dedicated their time to this study.”
While the study indicates promising results, the authors caution that the small sample size limits the generalisability of the findings. They recommend further testing with a larger, more diverse population and suggest that future versions of LUNA could integrate artificial intelligence to tailor mindfulness sessions or journaling prompts to individual users.
