In today’s digital era, smartphones capture thousands of photos, but users often forget to delete unwanted, duplicate, or blurry images. This leads to cluttered galleries and wasted storage space. The Smart Gallery Declutter Application aims to solve this problem by providing an intuitive and intelligent mobile solution that lets users clean up their gallery with simple gestures. By swiping right to keep and left to delete, users can quickly manage their photos. Additionally, AI-powered suggestions, batch deletion, and cloud backup features further enhance the usability and smartness of this tool. The app is developed using Flutter and Dart, ensuring smooth performance on both Android and iOS platforms.
