Trayzero brings David Allen's Getting Things Done (GTD) method to your phone. Free, open source, no ads, no account, no sign-up. Your data lives on your device. Always.
THE FIVE GTD STEPS, BUILT IN
Capture — one tap, anywhere.
A floating Capture button on every screen. Share anything from any app straight into your inbox. Voice-to-text for hands-free thoughts. A home-screen widget for the fastest possible "add to inbox."
Clarify — the killer flow.
Process Inbox runs you through your captures one at a time, card-stack style. Each card walks the full GTD decision tree: actionable? Two-minute rule? Delegate? Single step or a project? When? Where? You hit inbox-zero faster than you thought possible.
Organize — the canonical GTD lists.
Inbox, Next Actions, Projects, Waiting For, Someday/Maybe, Calendar, Reference. Plus a real Project type with outcome, next-action warning, and Active / On Hold / Someday / Done / Dropped status. Seven default @-contexts you can extend (@phone, @computer, @errands, @home, @office, @anywhere, @waiting). Areas of Responsibility for the higher altitudes.
Reflect — a Weekly Review wizard.
A seven-step review walks you through the canonical GTD pass: clear inbox, review next actions, check waiting-for, scan calendar, review someday/maybe, look at projects, set next week's intentions. Daily review supported too.
