Most habit trackers punish a single missed day, so Neohabit lets you build routines that happen X times in Y days, like three workouts in five days or one deep-work session every three days, and adjust the target mid-streak as the habit gets easier. Your progress renders as GitHub-style contribution heatmaps in three styles: monochromatic grids for simple check-ins, numeric grids that record values such as calories, spending, reps, or hours up to two billion, and fractured grids that split each period into up to sixteen segments for habits done many times a day. Related habits group into projects with a one-dimensional daily view, and skill trees let you plan progressions, for example raising a reading target from twenty minutes to an hour in planned steps. You can ease into a new routine by starting at once in four days instead of daily, track things you want to reduce as well as build, hover any cell for period details, and rearrange projects and habits by dragging them. Multiple accounts, light and dark themes, keyboard shortcuts, and a polished mobile browser interface round out daily use, and a single command brings the whole thing up with prebuilt images ready to go.
