In the style of a Trello board, I used https://huntr.co/ https://huntr.co/ for my last couple (within a short span) job searches. It was free at the time but I donated to the dev since I felt it was worth the amount of time it saved me from tracking elsewhere. You can customize your columns, add company info, notes, files, tasks (with scheduling), and it has a nice contact discovery feature for the companies it knows about. The Chrome extension is nice to have. I haven't used any of the mobile apps as they didn't exist when I was using it. The dev was very responsive to the one feature request I had which he was already working on. The free plan is enough to see if it fits you or not without too much work.
