Get your in-tray to zero with Trayzero, a private, offline task manager built around the Getting Things Done (GTD) method. Capture loose thoughts, turn them into clear next actions, and choose what to do next. Your tasks, notes and attachments are stored on your device. No Trayzero account is required. Every feature is available without a purchase, and there are no ads. Capture what is on your mind Add tasks from anywhere in the app, share text and links into your inbox, or use the Home Screen widget. Dictate a thought with your device's speech recognizer, and attach photos or voice memos. Clarify your inbox Process Inbox guides you through each item: Is it actionable? Can you do it in two minutes? Is it a next action, a project, something to delegate, or something for later? Empty your inbox by deciding what each item means. Organize your commitments Keep Next Actions, Projects, Waiting For, Someday/Maybe, Calendar and Reference in dedicated lists. Give projects an outcome and see which ones need a next action. Use contexts, tags and Areas of Responsibility to organize work and life. Choose the next action Filter actions by context, available time and energy. Build a daily plan and find work that fits the moment, whether you have five minutes at home or an hour at your computer. Keep your system current A guided Weekly Review helps you capture loose ends, clear your inbox, and review actions, waiting items, projects, your calendar and Someday/Maybe. Save your progress and continue later. Remember what matters Set due dates, deferred actions, waiting-for follow-ups and repeating tasks. Reminder notifications offer actions such as Done and Snooze. Optional system-calendar integration works with the calendar you choose. Notification delivery depends on your device permissions and settings. Bring your tasks with you Import supported exports from Todoist, TickTick, Nirvana, Google Tasks, Things 3 and OmniFocus, or paste a plain-text list. On iPhone and iPad, import selected Apple Reminders lists, or connect to Microsoft To Do for a one-time import. Preview before importing and undo an import if needed. Export formats and supported fields vary by source. Own your backups Export and restore portable JSON backups, including attachments. Enable automatic backups to a folder you choose. Backups are unencrypted; if you choose a cloud-synced folder, its provider handles synchronization. Trayzero does not provide cross-device task sync. Privacy with clear choices Your task content is not sent to a Trayzero server. Optional Microsoft imports, system-calendar integration, speech recognition and shared backups use the services you choose. Store builds use RevenueCat for anonymous purchase checks and purchase/customer analytics; your tasks are not included. See the privacy policy for details. Free and open source Light and dark themes, adjustable appearance, and accessibility support are included. Optional tips and a supporter subscription help the independent developer; they do not unlock features. Explore the source at github.com/roman10/trayzero.

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.
