Trayzero brings David Allen's Getting Things Done (GTD) method to your iPhone. Free, 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 Friday 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. Engage - do now. The Engage tab filters Next Actions by Context, Energy (low / medium / high), and Time Available (under 5m / 15m / 30m / 1h). Pull up the actions that match the moment you're in. REMINDERS THAT ACTUALLY WORK Due-date, defer-until, waiting-for follow-up, and weekly-review nudges fire as system notifications with action buttons - Done, Snooze, Move to Next Actions. Calendar two-way sync mirrors dated items into your system calendar. VOICE, PHOTOS, AUDIO Capture by voice. Attach photos or voice memos to any item. PRIVACY YOU DON'T HAVE TO THINK ABOUT - 100% on-device. SQLite under the hood. - No account, no servers, no analytics. - Crash reporting is opt-in and off by default. - Backup/restore as plain JSON: you own your data, you can take it anywhere. WHO IT'S FOR - GTD practitioners who want a clean, focused app that respects the method. - Anyone tired of cloud-syncing personal task data through someone else's servers. - People who want their tasks where their phone is - and nowhere else.
