Quick answer: Pick by the job, not the category. Todoist and Microsoft To Do hold work that would otherwise be forgotten. TickTick covers tasks and habits in one app. Notion and Obsidian build systems you design. Loop and HabitNow track repeated behaviour with almost no setup. Structured lays the day on a timeline. Routinery runs a sequence with a timer. All eleven are compared below on price, platforms and what reviewers actually write about.
Most productivity roundups rank by a rating and stop. We had 32,022 public reviews sitting in a file, our own app included, so we looked at what people write, not only at the number they leave.
The ratings below come from official Google Play listings. Our own sample is used for themes only, and the section at the end explains why we drew that line.
The comparison: twelve apps at a glance
| App | Best for | Play rating | Price | Platforms |
|---|---|---|---|---|
| Loop Habit Tracker | Repeated behaviour, nothing else | 4.73 | Free, no ads | Android only |
| HabitNow | Habit tracking with more structure | 4.72 | Free tier | Android |
| Habitica | People who respond to game mechanics | 4.66 | Free tier, $4.99/mo | iOS, Android, Web |
| Todoist | Capturing work you would forget | 4.59 | Free tier, $6.99/mo | 9 platforms plus extensions |
| TickTick | Tasks and habits in one app | 4.59 | Free tier, $3.99/mo | 8 platforms |
| Microsoft To Do | Spending nothing at all | 4.58 | Free, no paid tier | iOS, Android, Windows, Web |
| Notion | Building the system yourself | 4.58 | Free tier, $11.99/mo | 7 platforms |
| Structured | Seeing the day as a timeline | 4.54 | Free tier, $2.99 to $6.99/mo | Apple and Web |
| Routinery | Being walked through a sequence, step by step | 4.52 | Free tier, $5.00/mo | Apple, Android |
| Habitify | Cross-platform habit tracking | 4.26 | Free tier | iOS, Android |
| Fabulous | Guided programmes | 3.89 | Free tier | iOS, Android |
| Productive | Habit tracking with reminders | 3.73 | Free tier | iOS, Android |
We make Routinery. It sits in the table on the same Play rating as everything else, which puts it ninth of twelve, and the section below says what it does badly as well as what it does well. Leaving our own app out would have made the table shorter without making it more honest.
How to choose: start from the job, not the category
You forget things. A task manager. Todoist runs on nine platforms plus browser extensions, which matters when the thing you forget happens at a desk you are not sitting at. Microsoft To Do costs nothing and has no paid tier, so there is no feature held back.
You remember and want the record. A habit tracker. Loop is free with no ads and no habit limit, and it is Android only. HabitNow covers similar ground with more structure.
Both, in one place. TickTick. It carries lists and a habit section and a Pomodoro timer, at $3.99 per month or $35.99 per year.
You want to design your own system. Notion or Obsidian. Both give you exactly what you build, and both charge you an evening of setup first.
You think in hours. Structured lays the day on a vertical timeline and includes a Pomodoro timer in its free tier. There is no Android app.
Points and levels work on you. Habitica. You will know within a week whether they do.
If you want the deeper comparison of what separates these categories, we cover it in habit tracker versus to-do list versus routine planner.
What reviewers write about: simplicity decides more than features
Across 32,022 reviews of these apps, the reviews that praise an app for being simple average 4.80 stars. The ones that call an app complicated average 2.72. The overall average is 3.96.
That gap is wider than any feature comparison in this article, and it splits the list cleanly:
| App | Praise simplicity | Complain of complexity |
|---|---|---|
| Loop Habit Tracker | 6.6% | 0.5% |
| HabitNow | 1.7% | 0.7% |
| Habitify | 1.6% | 0.9% |
| Microsoft To Do | 1.5% | 0.2% |
| TickTick | 1.3% | 0.9% |
| Todoist | 1.1% | 1.1% |
| Productive | 1.0% | 0.6% |
| Structured | 1.0% | 1.1% |
| Notion | 0.5% | 1.6% |
| Fabulous | 0.3% | 4.6% |
| Habitica | 0.2% | 1.4% |
Loop sits at one end with 6.6 percent praising simplicity against 0.5 percent complaining of complexity. Fabulous sits at the other with 0.3 percent against 4.6 percent.
A high rate does not make an app better. It reflects what that app's reviewers chose to write about, and apps attract different reviewers. Habitica users who enjoy the game are unlikely to use the word simple, and that is not a fault.
The direction matches what habit research reports. A 2026 preregistered reanalysis of 254 adults over 6 months found 6 of the 10 factors it tested were significantly associated with habit strength, and perceived difficulty was the only one with a negative association. It shows association rather than cause, and the sample was observational data gathered during the pandemic. An app that feels like work is difficulty arriving early.
The other half is what a daily log costs. In the SMARTER trial, 502 adults self monitored their diet for a year and average adherence was 51.6 percent (SD 39.3), with higher adherence associated with greater odds of losing at least 5 percent of body weight (adjusted OR 1.25, 95% CI 1.19 to 1.31). Logging works when it happens, and about half the time it does not.
Inside the simplicity reviews, what people mean is mostly visual. The screen or interface comes up in 31.1 percent of them. Having few features comes up in 1.1 percent. People are not asking for less capability, they are asking not to see all of it at once. The habit tracker roundup goes through what each tracker actually shows on that first screen.
Who stayed: reviews that mention months or years
We also counted reviews where someone mentions using the app for months or years.
Loop leads at 2.8 percent, then TickTick at 2.4 percent, Todoist at 1.5 percent, Habitica at 1.4 percent and HabitNow at 1.3 percent. At the bottom, Structured and Fabulous sit at 0.4 percent.
Treat this loosely. Most long-term users never mention how long they have used something, so these are floors and the differences between neighbouring apps mean little. The gap between 2.8 and 0.4 percent is the part worth noticing.
Routinery: what the rating doesn't tell you
We make Routinery, so read this against the links rather than against our word for it.
What the 4.52 hides. A Play rating is one number for twelve very different jobs, and ours is dragged around by people who wanted a habit checklist and got a timed sequence instead. The job it actually does is running the routine while you do it. Each step has its own duration, the app counts it down, and it cues the next one by voice or by push notification, so it can run silently if a talking app is wrong for where you are.
When that helps. When you already know what to do and still don't start. The gap between knowing and starting is the only thing this app addresses, and none of the eleven others target it directly.
When it doesn't. Capturing one-off work with a deadline, which is what Todoist and TickTick are for. Building your own system, which is Notion. Or tracking a bare habit with nothing around it, which Loop does for free and does well. Our roundup of routine planner apps covers the rest of that category.
What it costs. Two routines with unlimited checklists on the free tier. Paid access is $5.00 per month or $36.00 per year.
Method: why the ratings and the themes come from different places
The ratings in the first table are the official Google Play numbers, read on 2026-08-23. The theme percentages come from our own sample of up to 3,000 recent reviews per app, 32,022 in total, covering 2018-12-22 to 2026-08-19.
We kept those separate on purpose. When we compared our sample's average rating against the official rating, every one of the eleven apps came out lower in our sample. Loop was almost identical at 4.73 against 4.72, but Todoist was 4.59 against 3.81, Microsoft To Do 4.58 against 3.70, and Fabulous 3.89 against 2.86.
Eleven out of eleven pointing the same direction is not eleven apps getting worse. It is a biased sample. People write reviews when something annoys them, and satisfied reviews accumulate over years, so a slice of the newest reviews drops most of the second group.
That makes our sample useful for what people talk about and useless for ranking. So we ranked with the official numbers and used our own data only for themes.
Other limits: Android only, because the Apple review feed returned empty for every app we tried in August 2026. Phrase matching misses reviews that describe something in wording we did not anticipate, so every theme count is a floor.
Frequently asked questions: choosing productivity apps
What are the best productivity tools for busy professionals?
It depends which of three problems you have. If work falls out of your head, a task manager solves it, and Todoist covers the most platforms at nine plus browser extensions while Microsoft To Do costs nothing. If you already capture everything and want repeated behaviour to stick, a habit tracker is the right category, and Loop is free with no ads. If you know what to do and still do not start, neither category helps and a timed routine runner is the closer fit. Check which of the three you already own before adding a fourth.
Which productivity app has the best rating?
Loop Habit Tracker at 4.73 on Google Play from 63,072 ratings, followed by HabitNow at 4.72 and Habitica at 4.66. Ratings across this category cluster tightly, though, with seven of the eleven apps between 4.5 and 4.8, so the number separates them less than it looks. Loop is also Android only and deliberately narrow, which is part of why it rates so well and also why it will not suit everyone. Read the rating alongside what the app is trying to be.
Is a free productivity app good enough?
Often yes. Microsoft To Do is completely free with no paid tier and no in-app purchases on either store. Loop is free with no ads and no habit limit. Both rate above 4.5. Paid tiers in this category mostly buy calendar integration, unlimited projects and cross-device sync, so the question is whether you need those specifically. Start on a free tier for a week and upgrade when you hit an actual wall rather than in advance.
Why do these apps rate lower in recent reviews?
They mostly do not. When we compared our sample of recent reviews against official ratings, all eleven apps came out lower, which is a sign of how the sample was drawn rather than a change in the apps. People write reviews when something annoys them, and years of satisfied reviews sit outside a slice of the newest ones. This is why we ranked the apps with official store ratings and used our own review data only for what people write about.
Should I use one app or several?
Several, with clearly split jobs, is a common and workable setup. A task manager for work and a routine runner for the fixed sequences at either end of the day covers two different failures without either app doing both badly. What does not work is running two apps in the same category, which turns into deciding where something goes every time you capture it. If you already own three productivity apps and use one, delete the other two rather than looking for a fourth.
Method notes: sources, sample and limits
Ratings. Official Google Play listings, read 2026-08-23.
Themes. 32,022 public Google Play reviews across the apps above, our own app included, up to 3,000 newest per app, covering 2018-12-22 to 2026-08-19. Each review matched against fixed phrase sets. A review counts once per theme.
Limits. Android only. Recent-review samples skew negative against lifetime ratings, so they are not used for ranking. Phrase matching undercounts.
