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.

ProjectBoard — projects, tasks, notes, and files in one place. Everything a project needs lives together: the tasks, the notes, the files, and the conversation. No more scattering one project across four apps. PLAN YOUR DAY, NOT JUST YOUR LIST Drag a task onto the calendar to block time for it. Let Plan My Day pack your tasks into the gaps you actually have free — it reads your real calendar, so it schedules around meetings instead of pretending they don't exist. Start a focus session and work a block at a time. TASKS THAT MATCH HOW YOU THINK Subtasks for the steps. #tags across projects. Saved smart lists for the views you return to. An Inbox that catches anything you haven't sorted yet. WRITES THE BORING PARTS FOR YOU — ON DEVICE Smart Fill turns a sentence into a task with the right date, project, and priority. Your Daily Brief tells you what matters this morning. Smart Inbox Triage sorts what piled up. Search understands what you meant, not just what you typed. It runs on your device. ON EVERY SCREEN YOU OWN A genuine Mac app — split view, menu bar commands, keyboard shortcuts throughout. iPhone and iPad. An Apple Watch app for checking off work from your wrist. Home and Lock Screen widgets you can tap to complete a task. Shortcuts and voice for capture without opening anything. FILES WHERE YOU EXPECT THEM A ProjectBoard folder in Finder and the Files app, syncing both ways. Open documents straight in from Finder, or share them in from any app. Annotate with inline markup. BUILT FOR WORKING TOGETHER Share a project, chat alongside the work, and watch tasks and notes update live as your team moves. START FASTER Seven built-in project templates, or build your own with tasks that schedule themselves relative to your start date or deadline.
