Read full description

Task It is a realtime coordination app designed for small crews and teams. Start collaborating instantly with zero registration friction—simply create or join a room using a nine-digit code and password. Key Features: • Task Reading Tap any task to hear it read aloud. The app speaks the due date, time, assignee, and full task content using text-to-speech. If a voice note was recorded, it plays automatically after the summary. Perfect for busy work environments where you can't look at your phone. • Instant Collaboration Join rooms immediately with anonymous worker profiles. No upfront registration required—decide later if you need a permanent account. • Role-Based Permissions Work efficiently with clear roles: Owners have full control, Managers handle day-to-day operations, Participants execute tasks, and Virtual Assistants serve as placeholders for delegation. • Flexible Task Capture Create tasks with typed instructions or voice recordings. The read-aloud feature makes it easy to review tasks without stopping your work. • Realtime Synchronization All updates sync instantly across all devices.
