What Trayzero is
Trayzero is a Getting Things Done app for capturing thoughts, processing an inbox, and organizing tasks and projects on iOS and Android. Its card-based Process Inbox helps decide whether an item is actionable, delegated, deferred, or dropped. Work can be arranged in Next Actions, Projects, Waiting For, Someday/Maybe, Calendar, and Reference lists, with contexts and Areas of Responsibility. A seven-step Weekly Review guides regular list checks, while next actions can be filtered by context, energy, and available time. Capture options include voice-to-text, sharing from other apps, a home-screen widget, and photo or voice-memo attachments. Local reminders include action buttons, and optional two-way system-calendar sync is available. Tasks remain in an on-device SQLite database; the maker says there is no account, task server, or cloud sync. JSON backup import and export are supported. The source is public under GPLv3. The Free plan costs nothing, with all features, no ads, and no account required.
