Time management:
You can plan your day, work on projects etc. It’s easy to change order and duration of tasks, times are calculated on each change and it’s saved (automatically) by the system. So if you change a previous task, there’s no need to change all other tasks succeeding this one, like you usually have to do with calendar apps.
Pricing:
You can set hourly price for each task in freelancer mode. Task price is then calculated based on duration and hourly price. At the bottom of the table you can see sum of all duration and task prices.
Event planning:
Event planning can be easily done with changing order and duration of events and adding new and deleting deprecated events.
