I'm not sure what you want to track but I'd recommend becoming a stationary nerd . Experiment with different notebooks, paper quality, try fountain pens, pencils, pastels... Pick the combination that brings you joy. If you find pleasure in the tactile act of putting ink (or graphite) on paper, you'll never want to quit journaling. Believe me.

I'm only half joking. Physical, handmade artefacts beat everything else, and will outlive whatever tracking app is currently trending.

Start on YT and go down the rabbit hole.
