Habit tracker widgets, and the maths nobody does

The problem in one line

Nearly every habit widget on Android shows exactly one habit.

Loop Habit Tracker is the clearest example, because it is open source and you can go and count. It ships six widget types — Checkmark, History, Score, Frequency, Streak and Target — and every single one is scoped to a single habit. That is not a criticism of Loop; it is the convention in the category.

So do the arithmetic. You track eight habits. One widget each is eight widgets. A typical Android home screen is a 4×5 grid, and the smallest useful habit widget is 2×1. Eight of them is 16 of your 20 cells, before a clock, before a single app icon.

The three ways out

1. A stack that cycles

One slot, several habits, swipe between them. Loop's stack widget does this. It solves the space problem and creates a new one: what is on screen is whichever habit you last swiped to, so the glance-without-thinking property is gone. You are back to interacting with an app, just a smaller one.

2. Pick your three

Accept the limit and choose the three habits that most need the nudge. This is the option most people arrive at by accident, and it is genuinely fine — arguably better, since three visible habits beat eight invisible ones. Worth choosing deliberately rather than drifting into.

3. One widget for the whole day

Instead of one habit per widget, one widget showing today as a whole. A count, a ring, a plant that grows — the specific metaphor matters less than the property: fixed size no matter how many habits you track. Eight habits, twenty habits, same one widget.

The trade is precision. A summary tells you that four of eight are done, not which four. In practice that is the right trade, because the job of the widget is to make you open the app on the days you were drifting — not to be the app.

The other thing to check: can you tap it?

There are two kinds of habit widget and the difference is larger than it sounds.

Most widget screenshots in store listings are charts, because charts photograph better. Charts are the ones you stop looking at after a fortnight. The widget that earns its space is the one that removes taps on the days you nearly did not bother.

How to lay out a home screen you keep

1. Start with one summary widget, not five per-habit ones Put it where your thumb already goes. Its job is to catch the days you are drifting.
2. Add a control widget for the one habit you keep missing Not your easiest habit — the one you skip. One tap, no app.
3. Put the charts on the second screen, or nowhere Heatmaps and trends are for Sunday, not for Tuesday morning. They do not need prime space.
4. Give it two weeks, then delete whatever you stopped seeing A widget you have learned to look past is worse than no widget: it is occupying the spot a useful one could have.

Where Kaizenly sits, and the disclosure

Kaizenly is our app. It has four widgets, which is fewer than Loop's six, so take the following as description rather than a claim to win on count.

• Progress plant — the whole-day summary from option 3. A plant that grows as today fills up. Same size whether you track three habits or twenty.
• Single habit — a control, not a chart. Tick a habit, or start its stopwatch, without opening anything.
• Habit heatmap — a year at a glance. A chart, and we would put it on the second screen ourselves.
• Trend — where the line is heading. Also a chart.

If you want a per-habit widget for day-of-week frequency or a dedicated streak widget, Loop has those and we do not. The full comparison is here →
