This list is narrower than most productivity-app roundups. It isn't task managers (Todoist, Things, Linear all do that better than any generalist app), and it isn't calendar tooling (covered separately). It's the specific category of goal-and-habit tracking — the apps that help you stay on a multi-week or multi-month commitment without losing the thread. The category matters because most productivity failures aren't planning failures; they're follow-through failures, and the tools that close that gap look different from the tools that schedule the next hour.
Four of the six below have free tiers that are genuinely usable rather than demo-grade. The two that don't (Streaks and Way of Life) are one-time purchases under $5, so the lifetime cost is still trivial compared to a single month of most subscription productivity tools. The whole stack, if you ran every one, would cost less than a Netflix subscription.
The honest meta-point: app-switching is itself a habit failure. Picking the one that fits the way you naturally check in with yourself — daily, weekly, ritual-based, data-curious — matters more than picking the technically best one. Test one for a fortnight before adding a second.
1. Notion (free)
Notion belongs at the top of this list less because it's the best dedicated tracker and more because it's the one most people will actually keep using. The reason is the same one that made it the dominant doc tool of the last five years: it bends to your workflow rather than imposing one. A weekly review template, a monthly goals page, a habit grid, an annual reflection — all live in the same workspace as the rest of your thinking, so checking in doesn't require opening a separate app you'll forget about.
The trap is over-building. The Notion templates marketplace will sell you a "second brain" system with 40 interconnected databases that takes six weeks to configure and you'll abandon by week seven. Start with one page: today's plan, this week's three priorities, this quarter's two goals. Add complexity only when the simple version proves insufficient.
Best for: people who already use Notion for documents and want goals to live in the same place. Free tier covers personal use; Plus at $10/month adds Notion AI and unlimited file uploads.
2. Habitica (free)
Habitica gamifies habit tracking by turning your daily routine into a role-playing game: complete a habit, gain XP; skip it, take damage; level up your character, unlock equipment, join parties with friends who also lose health when you skip your morning run. The mechanic sounds frivolous and works better than most "serious" trackers because it bypasses the willpower question entirely — you do the thing because your party will lose the boss fight if you don't.
The model isn't for everyone. Some users find the game layer charming, some find it distracting from the underlying habit. The honest test: install it, run it for two weeks, and notice whether you're checking in for the game or for the habit. Either answer is fine; both produce the desired behaviour.
Best for: people who genuinely enjoy game mechanics, and the socially-motivated who'll do for a party what they won't do for themselves. Free, with optional cosmetic upgrades.
3. Streaks ($4.99 one-time)
Streaks is the iOS app that won the "habit grid" category by being ruthlessly simple: pick up to twelve habits, complete them daily, watch the streak counter grow, lose the streak if you miss two days in a row. The two-day grace period (rather than punishing a single miss) is the design decision that makes the app sustainable rather than demoralising — the streak you've built becomes worth defending without becoming brittle.
Integration with HealthKit is unusually deep: a "10,000 steps" or "30 minutes of mindfulness" habit auto-completes when your watch logs the data, so the streak isn't dependent on remembering to tap the app. The result is closer to a passive check-in than active maintenance.
Best for: iOS-only users with health and fitness habits who want a grid view of the month at a glance. $4.99 one-time, no subscription.
4. TickTick (freemium)
TickTick is best understood as Todoist + habit tracker + Pomodoro timer in one app, at a notably lower price point than running the three separately. The habit tracker is the part most relevant here: schedulable habits with reminder times, weekly/monthly views, and integration with the task list so a habit naturally becomes a task that recurs.
The reason to choose TickTick over standalone tools is the integration. The artificial separation between "tasks" and "habits" dissolves once both live in the same view, and the daily plan starts to look like what it actually is — a mix of one-off work and recurring routines competing for the same hours.
Best for: people who want one app instead of three, and don't already have a task manager they love. Free tier covers most personal use; Premium at $35.99/year unlocks calendar views, custom filters and richer habit analytics.
5. Way of Life ($4.99 one-time)
Way of Life is the oldest app in this category and still one of the cleanest. Each habit is a coloured square per day — green for done, red for skipped, yellow for partial, grey for unmarked — and the resulting grid view across a month is one of the most honest representations of behaviour over time available in software. The data is exportable as CSV, which the data-curious will appreciate.
It deliberately doesn't gamify, score or rank. The interface is closer to a journal than a game. For users for whom gamification feels infantilising, Way of Life is the antidote — the app gets out of the way and presents the data, and the response to that data is left to the user.
Best for: users who want quiet, data-rich habit tracking without game mechanics or social pressure. $4.99 one-time on iOS and Android.
6. Strides (freemium)
Strides differs from the others by supporting four distinct goal types in one app: yes/no habits, quantitative targets ("3000 steps daily"), milestones with a deadline ("finish first draft by July 1"), and average targets ("average 7 hours of sleep this week"). For people who naturally think about goals in different units, this flexibility is the killer feature.
The free tier limits you to a small number of tracked items, which for many users is exactly right — the discipline of choosing your five most important commitments is the value. Pro at $4.99/month or $29.99/year removes the cap and adds richer reporting.
Best for: people whose goals don't fit a simple "did/didn't" frame and need quantitative or milestone-based tracking. Free for up to five trackers; Pro from $4.99/month.
How to actually pick
The honest sorting:
- If you already live in Notion: stay there. Don't add another app.
- If you respond to games: Habitica.
- If you want quiet, visual, data-rich: Way of Life.
- If you want one app for everything: TickTick.
- If you want passive auto-tracking from your Watch: Streaks.
- If your goals are quantitative and varied: Strides.
The deeper observation, after watching hundreds of people try and fail to make habit tracking stick: the app is the smallest variable. The two larger ones are the cue (what triggers the check-in — usually a fixed time and place, like "after morning coffee, sit on the couch and open the app for 60 seconds") and the review (an honest weekly look at the grid, ideally written down, asking which habits are holding and which are quietly dying). Without both, no app will save the practice. With both, almost any of these six will work.
A second pattern worth naming: the practitioners who get the most from habit tracking are the ones who use it for a small number of habits — usually three to six — rather than trying to track every behaviour at once. The mind treats fifteen tracked habits as a chore; it treats four tracked habits as a focus. The discipline of choosing the four that genuinely matter this quarter, and ignoring the others until the chosen four are automatic, is the practice underneath the app. Most app-shopping is downstream of that choice not having been made.
The third pattern is that habit tracking has a natural lifespan per habit. A new habit benefits from being tracked for roughly 60 to 90 days, after which the behaviour is either established (and the tracking becomes ceremonial) or it isn't (and the tracking is hiding the failure). The healthy move at the 90-day mark is to either drop the tracking on that habit (it's now automatic) or be honest that it isn't working and either change the habit or accept that this isn't the right season for it. Tracking the same habit for years without it being established is the symptom of a different problem than the tracking can solve.
Habit tracking is the execution layer on top of a goal-setting practice, which is itself the execution layer on top of a values-clarification practice. The apps above handle the first; the books in our best productivity books roundup and our positive psychology reading list cover the underneath layers. For the broader productivity toolkit, our 55 productivity tools roundup extends to the work-execution side, and the full archive lives at the productivity topic page.
