Apart from the browser plugin, you can also use TimeCamp Power-Up in Trello. It will allow you to track time and generate time reports on any Trello card to know on which tasks you spent most of your time. Gain insights on projects without leaving Trello.
To work properly, integration with Trello must be enabled on your TimeCamp account first.
Add Trello power-up
To enable the Power-up first please open a board in Trello and click the Power-Ups menu and next Add Power-Ups.
Find Time Tracking by TimeCamp power-up on the list and click the Enable button.
Repeat these steps for each board, where you’d like to enable the time-tracking feature. Power-up must be enabled on every board separately
Track time with Trello power-up
To track time in Trello first open the card, that you would like to track time against. Next click the Track time button on the right side.
If you’re not signed in to the power-up yet please use the credentials of your TimeCamp account. If you are already signed in, you can click the Start timer button to start a new timer and click the Stop timer to stop it.
You can also put the number of hours in decimal format to add time manually and then click Add Time.
Modify tracked time
If you'd like to edit your tracked time please open the card, in which you would like to modify your time. Next, in the TimeCamp Time Report section find the time entry you would like to modify or delete and click on its duration. You'll be redirected to your web Timesheet where you can edit time entries. 
Add estimate
Under the TimeCamp Time Report section, you can find an option to add estimate time. This value will be automatically synced and imported as Budget to TimeCamp.
Click on the Add estimate option.
Next, input an estimated hours value for this task and click anywhere outside the field.
After adding estimates a small graph next to the tracked time will appear showing how many hours are already used.
