Ballast gives you one short reading each morning, then asks you to score how the day actually went in four areas: Focus, Love, Money and Energy. After a few weeks the wheel shows which part of your life you are quietly starving. Four spokes, each a 30-day average, with today's score as a ring on it. The area you have ignored longest is drawn faint, so the thin side of your month is the first thing you see. Drawn from your own numbers, and it only moves when they do.
