With the growing number of seniors affected by dementia, early prevention and mental stimulation are becoming crucial public health priorities. Many older adults lack accessible, motivating tools to keep their minds active and delay cognitive decline. Our startup idea focuses on developing an intuitive mobile application designed to support seniors in maintaining cognitive health. The platform offers personalized brain-training exercises, memory games, and emotional well-being modules. Using gamification and adaptive algorithms, it encourages regular engagement while collecting anonymized data to monitor cognitive trends over time. We are currently at the concept stage, building the first mock-ups and consulting healthcare experts. The next phase includes prototype development and pilot testing with local senior communities.
