The team and I are building HourStack - https://hourstack.com. We are focused on scheduling and tracking time at the task level, which works well with billable hours. We also integrate with task, event, and issue platforms so you can drag existing tasks onto your calendar to schedule and track time against them.

This can be quite nice when working with clients across different platforms like Asana, Trello, and GitHub.

As for downsides, we are a young company and don’t have the full feature set built yet. We are working hard though and making great progress.
