] | ### TL;DR
Don't think "time tracking." Think "cycle time" instead.
### Kanban Should Measure Cycle Time
Generally, Kanban is not about measuring "activities" at a granular level; it is about measuring cycle time for a pull through the entire system.

] | Disclaimer: I am related to Eylean board development
There is a precise match solution launched instead of Eylean which covers the idea of using both Cycle time and time tracking as part of Kanban System. If it is still relevant option you can consider reviewing [Teamhood](https://teamhood.com)

It seems to me that you need a virtual Kanban board with build-in time tracking and reports.
