What apps actually help you understand your productivity, not just plan it?

I’ve tried tons of productivity tools, Notion, ClickUp, and Todoist, and they’re great for organizing tasks, but I feel like they don’t tell the story behind my performance. Some days I get a ton done, other days I crash, and I’d love to know why. Recently found the Grooves app, which tracks habits alongside mood and focus data. It claims to show how your routines impact energy or stress. Looks promising, but seems pretty new. Has anyone here tested it or found similar tools?
