Paper, spreadsheet, or app: choosing a habit tracker

Every habit tracker does the same job. You record whether you did a thing on a given day, and later you look at what those records add up to. A notebook does it. A spreadsheet does it. So does an app.

Because the job is identical, comparisons based on features are close to useless. What separates them is how each one breaks, and which kind of breaking you personally are prone to. So this is organised around failure, not features.

Fair warning about bias: this is published by a habit tracking app. I have tried to be straight about where paper wins, because a reader who picks the wrong tool and gives up in five weeks is no use to anyone.

Paper

A grid in a notebook. Habits down the side, days across the top, a pen.

The advantage is not aesthetic, though people talk about it that way. It is that paper has no other functions. Opening your phone to tick a box puts you one notification away from twenty minutes of something else, and that tax is invisible but real. A notebook cannot do anything except be a notebook.

The second advantage is friction in the right direction. Drawing next month's grid by hand takes about ten minutes, and during those ten minutes you decide, deliberately, which habits are worth writing down again. An app carries everything forward silently, which is convenient and quietly lets dead habits ride for months.

Where paper breaks: it cannot answer questions. Ask which day of the week you drop your gym habit and the honest answer is that you would have to count it by hand across four pages, so you will not. Anything longer than about two months is effectively unqueryable. It also cannot survive being left at home, and it does not sum anything for you.

Spreadsheet

A grid in a spreadsheet, usually with conditional formatting turning cells green and a few formulas totalling the columns.

This is the most capable option on this page and it is not close. You can compute anything: completion by weekday, rolling averages, correlations between two habits, a chart of any shape you want. Nothing here or anywhere else will match a spreadsheet for answering a question you did not anticipate.

It has two failure modes and they are both well known to anyone who has done it.

The first is that the spreadsheet becomes the hobby. An hour goes into the conditional formatting, then another into a summary tab, then the file gets rebuilt in February because the January layout was wrong. That hour is enjoyable and it is not habit tracking.

The second is phone entry. Every spreadsheet app on a phone is unpleasant to use for tapping one cell, and habit logging happens on a phone far more often than people plan for. Twenty seconds of pinch-zooming to find the right cell is enough friction to lose the habit of logging, which then loses the habit.

App

One tap, sums itself, works on a phone, does not need setting up each month.

The real advantage is that the cost of logging approaches zero, and low logging cost is what determines whether you are still tracking in March. The secondary advantage is that questions get answered without work: completion rates, streaks, weekday patterns are computed whether or not you were curious enough to build them.

Where apps break: they make it too easy to add habits. Adding a row costs one tap and no thought, so lists grow to twelve, and a twelve-row grid is the most reliable way to abandon habit tracking that has been discovered. Paper's ten minutes of manual grid-drawing is a feature that apps have optimised away.

They also carry lock-in. Your two years of data are in someone else's product, and if it shuts down or starts charging for something that used to be free, your history is the hostage. Check whether an export exists before you commit, and check what it actually contains: an export that only hands back a proprietary blob is not portability.

Side by side

So which one

A recommendation, since a comparison that refuses to reach one is a waste of your time.

• One or two habits, and you already keep a notebook: paper. Nothing else will beat the thing already open on your desk.
• You want to answer a specific question, like whether your running days follow your good sleep days: spreadsheet. Build it, answer the question, then move on.
• Four or more habits, logged mostly from a phone, and you want to still be doing this in six months: app.
• You have abandoned tracking twice before: app, with three habits. The logging cost is what killed the previous attempts, and that is the variable an app changes.
• You want to query the data in ways the tool never anticipated: spreadsheet, and accept the phone friction as the price.

The most common mistake is picking on capability. Spreadsheets are the most capable and they lose more people than either of the other two, because capability is not the constraint. The constraint is the ten seconds after you finish the habit.

Pick the tool that is open at the moment you need it. Everything else is preference.

The hybrid that works

One combination is worth mentioning because it sidesteps the worst of each. Log daily in whatever is fastest, and once a month spend fifteen minutes with the data somewhere you can think.

In practice that means tapping boxes on a phone all month, then at month end looking at the completion rates and the weekday breakdown and writing two lines somewhere about what to change. The daily loop stays cheap. The thinking happens somewhere the interface is not fighting you.

The cost is that you are doing the analysis a month behind, in a copy of the data rather than the live thing. If you want to poke at it continuously, use a spreadsheet as the primary record instead.

The short version

• All three record the same thing. Choose on how each one fails, not on features.
• Paper: no distractions and healthy friction, but it cannot answer a question.
• Spreadsheet: most capable, worst on a phone, and it becomes the hobby.
• App: lowest logging cost, which is the variable that decides month six, but it makes over-adding habits frictionless.
• One or two habits and a notebook on your desk? Use the notebook.
• Want to slice the data in ways nobody planned for? Use a spreadsheet and accept the friction.
• Abandoned tracking twice already? Use an app and cap yourself at three habits.

Whichever you pick, the decision that matters more than all of this is how many rows you put in it. Three, in any of the three tools, beats twelve in the best one.
