Would you pay for a job tracking app?

I had the idea of a job tracking app similar to huntr.co, but focused specific on developers by aggregating company info. I had a few ideas of specific starting features, but curious to hear feedback from others.

Basic Kanban style tracking at first
Tie in https://www.levels.fyi/ salary info
teamblind.com company reviews
Job hunters could tie leetcode questions asked in their interview back to the comany

Does this seem useful? If so, what would want to see from a service like that if you are paying for it?
