A goal tracking app and a habit tracker sit in the same App Store category, cost about the same, and look almost identical in screenshots. They compute different things. One answers "how far am I from the number, and will I get there by the date?" The other answers "did I show up today, and how often lately?" Most people install one, discover six weeks later that it can't answer the question they actually had, and blame themselves for not being consistent when the tool simply wasn't built to do that arithmetic.
This is the tooling version of the question. For the underlying argument about which one deserves your attention in the first place, habits vs goals is the concept post; this one is about what the software has to be able to calculate.
What a goal tracking app has to compute
Four things, and a habit tracker does none of them by design.
- A target quantity. Not a checkbox — a number you're accumulating toward. 24 books. 6,000 saved. 180 hours of practice.
- A deadline. Without a date, remaining time is undefined and everything below is uncomputable.
- Partial progress. Today added 40 pages, not "done". The unit is the increment, not the day.
- Pace, derived from the other three. Where you should be by now, where you actually are, and what the required rate is for whatever is left.
The fourth is the whole reason the category exists, and it's the one people don't realise they're missing until the year is nearly over.
A worked example, with the arithmetic done
Say the goal is 24 books this year. You track "read 20 pages" as a daily habit, and by 12 August — day 224 — your tracker shows 143 done-days. The heatmap looks genuinely good: a 64% completion rate over seven and a half months, no gap longer than five days, a couple of proud stretches in April.
None of that tells you the thing you needed. You've finished 10 books. Straight-line pace for 24 puts you at 14.7 by day 224, so you're nearly five behind. The projection is worse than the gap: 10 books in 224 days is one every 22 days, which lands the year at about 16. Hitting 24 now means 14 more in 141 days, one every 10 days, more than twice the rate you've actually managed while looking consistent.
The habit tracker is not lying to you. 143 done-days is real, and it's the input you control. But nothing in it can produce the number 16, because the tracker holds no target, no deadline and no idea how long a book is. That mismatch between "my heatmap looks healthy" and "I'm going to miss by eight books" is the most common way people get ambushed by a goal in November.
Where a habit tracker is the wrong tool
Being honest about this saves people a lot of friction. A habit tracker is the wrong choice when:
- The outcome isn't in your control. "Lose 8kg" depends on sleep, hormones and a scale with opinions. You can log a perfect month of done-days and watch the number sit still, which reads as failure and isn't.
- The thing is a project, not a repetition. Ship the app, pass the exam, renovate the kitchen. These have phases and dependencies, not a daily row.
- Partial credit is the point. Saving up for something means the total matters and the individual deposit doesn't. A streak of transfers tells you nothing about whether you'll make it.
- The deadline is real and external. An exam date doesn't care about your completion rate. It cares about how much is left.
For those, a purpose-built goal tracking app earns its slot. Strides is the long-standing one, built around targets with deadlines, running averages and multi-step projects. Griply goes further and hangs every habit off a goal inside a life area, so today's checkbox has a visible reason above it. Both are genuinely better than a habit tracker at the arithmetic in the section above, and worse at the thing below.
Where a goal tracker is the wrong tool
The mirror failure is subtler and hits harder. A goal tracker pays out once, at the end, and does nothing for you on an ordinary Wednesday in March. The habit-formation research is unromantic about this: the classic study on automaticity found repetition in a stable context was what built the behaviour, somewhere between 18 and 254 days of showing up. Setting a target doesn't shorten that. Only the repetitions do.
There's also a failure mode specific to the format. Goal trackers make it very easy to watch a progress bar move slowly and feel worse each time you open the app, because the bar is honest about a gap you can't close today. That's a real cost, and it's why the goal-first apps tend to be abandoned by people who were actually doing fine.
How to set up a goal in a habit tracker
You can get most of the way with a habit tracker alone if you do the translation deliberately.
- Write the target and the date somewhere outside the app — a note, a whiteboard. That's the compass, and it doesn't need to be in the tracker to work.
- Convert the target into a per-day or per-week quantity, then check that the number is survivable. 24 books works out at roughly 20 pages a day. If the converted number reads as impossible, the target was the problem and no amount of consistency was going to fix it.
- Track the action as a number with a unit rather than a checkbox — pages, minutes, kilometres, amounts saved — so a partial day counts as a partial day.
- Schedule it honestly. If the plan is five days a week, set it to five days a week so the two rest days don't register as misses. Weekly habits covers that setup.
- Once a month, do the pace arithmetic by hand: progress ÷ days elapsed × days in the period. Two minutes, and it's the number the daily view will never show you.
The practical setup most people end up with
After a year, the arrangement that survives tends to be lopsided. One or two real goals, written down somewhere unglamorous and reviewed monthly. Five or six habits tracked daily, none of which mention the goal at all. The tracker holds the actions because that's what daily attention should be spent on; the goals get looked at rarely enough that a slow week doesn't feel like a verdict.
If you want to read your own record properly when the monthly check comes round, what a habit tracker with statistics tells you covers which numbers are worth trusting. And if the goal in question is the reading one from the example above, building a reading habit has the sizing advice that makes 20 pages a night something you'd actually do on a Wednesday.
FAQ
What is a goal tracking app?
An app built around a target quantity and a deadline, so it can show progress toward the number and how far ahead or behind pace you are. That's the distinguishing feature: a goal tracker computes distance to a finish line, where a habit tracker counts the days you showed up.
Can a habit tracker be used for goals?
Yes, if you translate the goal into a repeatable action first and do the pace arithmetic yourself once a month. Track pages, minutes or amounts rather than checkboxes so partial days count. What you won't get automatically is a projection, which is exactly the number that tells you in August whether the year is going to land.
Which is better for weight loss or fitness targets?
Track the action, not the outcome, whichever app you pick. Sessions per week, steps, kilometres — things you fully control — belong in a habit tracker; the weight itself is an outcome that moves on its own schedule and makes a terrible daily metric. Check it monthly at most.
Does init.Habits do goal tracking?
Not in the target-with-deadline sense, and it's better to say so plainly. init.Habits is a habit tracker: checkbox, counter, number-with-unit, timer and Apple Health tracking modes, per-habit streaks with earned streak freezes called shields, and a GitHub-style heatmap of the whole year. If you need required-pace projections against a deadline, pair it with a note or a dedicated goal app.
