What is a task tracker, taking into account the time spent?

Question

Time Management

Greetings!
The topic has already been raised more than once, but among the answers I did not find what I needed.
And you need a task manager for freelancing to take into account the actual time spent.
1. Mandatory:
1.1. division of tasks by projects
1.2. accounting for time spent on a task. Both by the timer (sat down for the task - turned on the timer, walked away - paused, finished - stopped), and manually - if you forgot to turn on the timer in time, plus there should be the possibility of pausing the timer.
1.3. subtasks or task branching
1.4 task cost: fixed, in hours
1.5. reports on time and finances in total and separately for projects and tasks.
1.6. Russian interface
2. Very desirable:
2.1. the ability to quickly add tasks
2.2. lightness
2.3. saas, the presence of a free version for the test, well, even better if free
I came across the primaerp.com service, but it is still very raw.
