From Beauty Queen to Tech Advocate: Nancy Sumari Drives Change in Tanzania’s Classrooms


 DAR ES SALAAM: Former Miss Tanzania and Miss World Africa, Nancy Sumari, is redefining her public role by shifting from the pageant stage to championing education innovation and inclusive technology in Tanzania.

In an interview with the Daily News, Sumari said her experience in global beauty pageants did not alter her life’s purpose but instead strengthened her long-standing passion for teaching, children, and sustainable social impact.

“My purpose was already clear from a young age,” she said, recalling her early ambition to become a teacher and work closely with children.

That vision has since taken shape through her flagship innovation, the Kalimani App, a digital learning platform designed to support deaf and hard-of-hearing pupils in classrooms. The application recently earned international recognition after winning the Zero Project 2026 Innovation Award.

The Kalimani App features animated sign language tools and curriculum-based content aimed at improving access to education for learners with hearing impairments—many of whom often face systemic barriers in traditional classrooms.

Speaking in Dar es Salaam, Sumari explained that the idea behind the platform was inspired by her years of volunteering in primary schools, where she observed significant gaps in resources for children with hearing challenges.

“These students were not receiving the support they needed,” she noted, emphasizing the importance of practical and accessible technology for both school and home environments.

Currently used in at least 35 schools across the country, the app is being enhanced with artificial intelligence capabilities that can translate written text into sign language—an innovation expected to further advance inclusive education in Tanzania.

Beyond her work in education technology, Sumari also spoke about the challenges of balancing entrepreneurship, motherhood, and family life, describing it as a continuous process that requires resilience and strong support systems.

She also raised concern over increasing cases of online abuse, urging greater accountability and responsible behavior on digital platforms. According to her, values such as kindness must be nurtured at home, as online conduct often reflects real-life character.

Despite her demanding schedule, Sumari maintains a connection to music, particularly choir singing, which she described as a source of relaxation and personal grounding.

Her journey from beauty pageantry to social innovation reflects a broader commitment to impact-driven leadership, leveraging technology, education, and advocacy to expand opportunities for children and communities across Tanzania.
