Use case · Correlations
A habit tracker with correlation charts.
Habit Pocket has correlation charts: overlay any habit on any other, like bedtime against energy or workouts against mood, and watch what moves with what. Habit Pocket is a habit tracker that logs numbers, times of day and moods side by side, so you can see what your habits do to your sleep, mood and energy. Because it stores real numbers and times, not just checkmarks, the overlay shows the real values: steps climbing from 3,500 to 9,500 while weight starts a steady slide, on one timeline, with the exact values on hover.

Line charts and the candle overlay are Pro features. Free gives every habit a stats page with its stat cards and heatmap, which is enough to see how a habit is going before you decide to upgrade.
