It’s 11:40 at night. You have a Reddit thread open in one tab, two Play Store listings in the others, and a quiet conviction that the right to-do app is the missing piece. TickTick has a timer and a habit tracker built in. Todoist looks calmer. One commenter says TickTick changed their life. The next says the same about Todoist.
Maybe you’ve run this loop before. You installed one, spent a happy Sunday building lists and color-coding them, and by Thursday the icon was sitting on a small pile of overdue tasks you’d stopped wanting to look at.
So this isn’t a feature shootout. Both apps are good. The useful question for an ADHD brain is narrower: which one fits the specific way your days fall apart, and which one will you still be opening three weeks from now?
What actually matters in a task app when you have ADHD?
Start with an uncomfortable number. Quettra’s data shows that the average app loses 77% of its daily audience within three days of install. That’s everyone, not just people with ADHD. But ADHD adds a twist: the setup is the fun part. A new app is shiny, and building the system feels like progress. Using it on a dull Tuesday is the actual job.
So whichever app you pick, three things decide whether it survives the honeymoon.
How fast a thought gets in. If adding a task takes more than a few seconds, you’ll start keeping things in your head again, and your head is where they get lost. In a 2021 set of lab experiments with 172 people each, making it more effortful to offload information meant people offloaded less, and their performance on the task in front of them dropped.
Whether you see it again. A list you have to go looking for is a list you’ll forget exists. Both apps offer a widget for your home screen, and it’s the first thing to set up.
What happens to the things you didn’t do. This is the one that sneaks up on you. Both apps mark a dated task overdue once its day passes. Todoist’s own help center warns against letting overdue tasks “snowball from one day to the next”, and TickTick’s help pages have a name for the pile: “zombie tasks”. Once opening an app feels like opening a bill, an ADHD brain finds reasons not to. Anything that keeps score makes that worse, which is why we’re wary of streaks and points in task apps.
TickTick vs Todoist at a glance
| App | Price (US) | Ads | Account | Focus timer | The catch |
|---|---|---|---|---|---|
| TickTick | Free plan; Premium US$49.99/yr | No | Free account, for sync | Yes, Pomodoro-style | So many modules that setup can become the task |
| Todoist | Free plan; Pro US$60/yr or US$7/mo | No | Yes | No | Calendar layout and custom reminders are Pro |
| Noodl | Free | No | No | Yes, 5 to 120 min | Android only, no sync, far fewer features |
Prices are from each company’s pricing page, October 2026. Neither TickTick’s nor Todoist’s Google Play listing carries the “Contains ads” label.
Which is better for ADHD, TickTick or Todoist?
Neither wins outright, and the reason is useful. Psychologist Carey Heller, writing in CHADD’s Attention magazine, says that putting a calendar, task list and notes in one app “can be very useful for some individuals,” but that “some people find an all-inclusive app to be overwhelming.” TickTick is the all-inclusive app. Todoist is the focused one. Which half of that sentence describes you matters more than any feature list.
TickTick: everything in one app, if you can resist tinkering
TickTick’s pitch is that you never have to leave. Its beginner’s guide lists tasks, a calendar, an Eisenhower Matrix, a Pomodoro timer and a habit tracker as built-in modules. For an ADHD brain, fewer apps means fewer places for a task to slip through, and the timer sits one tab away from the list. If you struggle with time blindness, the free plan’s basic calendar view lets you see your schedule by day and month, while Todoist keeps its calendar layout for Pro.
The free plan is generous where ADHD tends to need it: two reminders per task, nine lists of 99 tasks each, and five habits. Premium is US$49.99 a year at the time of writing and mostly adds room: 299 lists, five reminders per task, and more calendar views.
The catch is the same thing that makes it appealing. There’s a lot here: lists, tags, filters, the matrix, habits, countdowns, themes, focus statistics. An ADHD brain that loves a fresh system can lose a whole evening configuring it and call that productivity. If you go with TickTick, open the tab bar settings, switch off everything you won’t use this week, and add things back only when you miss them.
Best for: ADHD brains who lose the thread when they switch apps, and want the timer, habits and calendar next to the list.
Todoist: the calm inbox, if capture is your weak spot
Todoist is built around getting things in fast. Its Quick Add reads plain language, so typing “Submit report every Friday at 4pm #Work” (Todoist’s own example) sets the date, the repeat and the project in one line. On Android you can add tasks from a Quick Add tile or a home-screen widget, and Ramble lets you say a task out loud instead, with limited sessions on the free plan.
The free plan is deliberately small: five personal projects, task reminders and three filter views. That cap can be a quiet gift if you’d otherwise build 40 projects on day one. According to Todoist’s pricing page, Pro is US$60 a year in the US, or US$7 if you pay monthly, and adds the calendar layout, custom task reminders, task durations and deadlines.
There are two catches. First, there’s no focus timer, so the starting part happens somewhere else: another app, or a browser tab running our free focus timer. Second, Karma. Every finished task earns points, hitting daily or weekly goals builds streaks, and you lose Karma points when tasks are five or more days overdue. That last rule lands on exactly the weeks ADHD makes hardest. You can switch Karma off completely, or set your daily and weekly goals to zero. Our full look at whether Todoist is ADHD-friendly goes deeper on both.
Best for: ADHD brains who mostly forget things before they’re written down, and would rather keep the list plain and bring their own timer.
Noodl: if both sound like more app than you want
If you read the last two sections and felt a bit tired, that’s worth noticing. Noodl is the app we make, so weigh this accordingly: it’s free, Android-only, and has no account and no ads. Today shows only today’s tasks, everything else waits in Plan, and a task that slips simply waits there instead of turning red. The focus timer runs from 5 to 120 minutes, and a five-minute start counts. It does far less than either app above, with no sync, no recurring tasks and no sub-tasks. For some brains that’s the point. For others it’s a dealbreaker.
Best for: people with ADHD who want a short list for today and a timer, without building a system first.
How do you make the one you pick actually stick?
Whichever app you choose, the first two weeks decide it.
Judge it in week two, not day two. The honeymoon is real, and so is the drop-off after it. Decide now that you’ll give it 14 days before you shop for another app.
Capture only, for the first week. No projects, no tags, no color scheme. Just get things out of your head and into the app. If something needs organizing, it will still need it next week.
Only give a date to things that really have one. The dentist gets a date. “Sort out the garage” doesn’t. A task without a date can’t go overdue, so the pile stays smaller. In Todoist, undated tasks stay out of your Today view, which keeps that screen honest.
Do a two-minute sweep once a week. Pick a day, open the app, and move anything overdue to a new date or delete it. No reviewing, no reflecting. Deleting a task you’re never going to do counts as finishing it.
What to try tomorrow
Pick the app whose catch you can live with, not the one with the longest feature list. If building systems is your trap, Todoist’s small free plan protects you from yourself. If switching between apps is where you lose the thread, TickTick keeps everything in one place.
Then tomorrow morning, before you open anything else, put three things in it. Just three. If by Friday you’re opening it without having to remind yourself to, you’ve found your app.
