Trayzero is a faithful Getting Things Done (GTD) application designed to help you capture anything, process your inbox with guided decisions, and keep your projects moving forward. It operates entirely on-device, ensuring your tasks never leave your personal storage. With no account required and no cloud synchronization, Trayzero prioritizes your privacy and control over your data. The app guides you through David Allen's five GTD steps: Capture, Clarify, Organize, Reflect, and Engage. It offers features like a one-tap capture inbox, a card-stack flow for processing your inbox according to the GTD decision tree, canonical lists for organizing tasks, and a guided Weekly Review wizard. You can engage with your tasks by filtering them based on context, energy level, and available time. Trayzero is available on both Android and iOS, offering a strict GTD implementation with a local-first approach, all for free.
