Two productivity apps become expensive when both own the same task. Every rename, date change, and completion then requires reconciliation, and the copies eventually disagree.
Assign ownership before entering data
Choose one task source of truth. It owns the task title, notes, dates, project membership, and completion state. Choose one window-context owner only if needed. It may record which current macOS windows belong to the project, but it should not become a second schedule.
Write this division in one sentence: “Things owns commitments; Wallo groups the windows used to carry them out.” If you instead use Wallo’s built-in to-dos, do not copy those same commitments into another personal list.
Test changes, not just creation
Rename a task, mark it complete, close a working window, and reopen the project. Observe which tool changes. Without an explicit integration, assume nothing propagates. A pasted link can provide navigation, but it does not create shared state or conflict resolution.
Remove unnecessary copies
Delete duplicate tasks after preserving any unique notes. Use a project name or short context clue in the window tool, not a full mirrored checklist. Review the ownership rule whenever an app adds an import or sync feature; verify direction, supported fields, and failure behavior before relying on it.
Wallo does not automatically detect duplicate tasks or synchronize Things, Reminders, or Todoist. Its goal can contain both Wallo to-dos and windows, but that convenience does not require reproducing an external task list.
