FlowSavvy mentions (1)

  • Task management app
    Since you mention also wanting to plan your schedule better, FlowSavvy might be worth a look (I helped build it). You throw everything in the todo list, and it'll do the planning into your calendar for you. Then if anything comes up, it automatically reschedules. Definitely makes scheduling tasks less tedious.

  • Show HN: General Task, a free task manager for builders (beta)
    This is a solid take on task management. We've got some similar features in https://hourstack.com with dragging and dropping tasks from other platforms into a calendar (team or personal).

    I would take a look at Plan (free), Hourstack (paid) or Sunsama (paid). Source: almost 5 years ago
  • Ask HN: How do you track your billable working hours?
    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... - Source: Hacker News / about 5 years ago
  • Be happier with your time by tracking how you spend it...
    Calendars - newdaynew.me or hourstack.com- calendar tracking is useful, but does make things rigid and remove some flexibility or freedom to how you spend you day - like putting in your calendar 3 hours of X when you may not be in the best mood to do that. Source: over 5 years ago
