Precipitation monitoring is fundamental for understanding climate variability, environmental planning, and water resource management, especially in regions with irregular rainfall regimes. This study aimed to develop and apply an educational application for recording, organizing, and analyzing pluviometric data in the municipality of Pinheiro, Maranhão, while promoting student engagement in scientific and technological practices. The Rain Observer application was developed using the Flutter framework and integrated with Google Forms and Excel Online, enabling automatic data storage and the creation of a continuous rainfall database. Daily precipitation measurements were conducted from January to August 2025 using a conventional 150 mm rain gauge installed at the Federal University of Maranhão, Campus Pinheiro, following GLOBE program protocols. The results indicate that the application improved data standardization, reliability, and recording efficiency, reducing errors associated with manual notes. The analysis revealed an average precipitation of 9.1 mm/day, with high temporal variability and rainfall events concentrated between January and April, typical of tropical climates. From an educational perspective, the project contributed to the development of scientific thinking, digital literacy, and environmental awareness, demonstrating the potential of educational applications for local climate data production and learning promotion in school environments.
