This "evaluation method" is the biggest challenge of the remote work era. Time-logs are the most important information for evaluating work correctly, and Timeboat records them. ▼Features & Differences from Similar Apps▼ [Half is Schedule] Half the screen displays schedules and the other half displays logs, allowing you to compare actual time spent with the planned schedule.
