10 Best To-Do List Apps for iPhone of 2026

Things 3 is the to-do app that feels most at home on an iPhone. Its structure is simple to learn: single to-dos with notes, tags and checklists, projects with headings for bigger goals, and areas for each part of your life. The Today and Upcoming lists put your to-dos next to calendar events, and a This Evening section keeps after-work plans apart. Cultured Code's App Store listing names the iOS hooks that matter: a Share extension for saving links as tasks, Siri, Shortcuts, widgets on the home and lock screens, import from Reminders and an Apple Watch app for checking off and dictating to-dos. Sync runs through the free Things Cloud service. The trade-offs are real. The iPhone app is a $9.99 one-time purchase, but the Mac, iPad and Vision Pro versions are sold separately, there is no Android or web app, and Things has no shared lists. If you plan alone on Apple devices, those limits rarely matter.

Apple Reminders is the best free to-do list app for iPhone, and it has grown well beyond simple alerts. Apple's App Store listing describes smart lists for Today, Scheduled, Flagged and Assigned to Me, custom smart lists built from tags, dates, locations, flags and priority, subtasks and section headers that can be shown as columns for a basic board. Reminders can repeat at custom intervals, fire when you arrive at a place or get in your car, and appear inside the Calendar app. Shared lists let others add and complete items, and you can assign reminders to people on the list. Grocery lists sort items into sections automatically, and templates save routines or packing lists for reuse. Natural language entry handles phrases such as jog every other morning. The limits are that it stays inside Apple's devices, and some Apple Intelligence features only work in certain languages and regions. For many households, it is all the task app they need.

TickTick covers more ground than any other app on this list at its price. The App Store listing describes a to-do app with checklists, four priority levels, tags, recurring tasks, email-to-task, attachments and shared lists, then adds a Pomo Timer, habit goals, countdowns and an AI Assistant. Reminders can fire by time or location, Siri can create tasks, and focus time syncs to Apple Health through HealthKit. The company says the app is always free, and Premium raises limits: 299 lists with 999 tasks each, five reminders per task, list sharing with up to 29 members, custom smart lists, calendar subscriptions and full calendar views. Premium costs $49.99 a year or $4.99 a month on the US App Store. TickTick also runs on Android and desktop, so it is a safer bet than Things if you might leave the iPhone. The cost of all that breadth is a busier interface than Things or Reminders.

Todoist is the best iPhone to-do app for people who do not live entirely in Apple's world. Its App Store listing highlights Quick Add, where typing a phrase such as submit report every Friday at 4pm #Work sets the date, repeat and project, and Ramble, which turns spoken descriptions into tasks. Projects can be shown as lists, boards or a calendar, with sub-tasks, sections, labels and priorities. Sharing is part of the core product: you can share projects, assign tasks, set deadlines and comment with file uploads. On iOS it supports Siri, widgets, the Apple Watch and location-based reminders, and it syncs to Mac, Android, Windows and browsers. The free Beginner plan gives 5 personal projects, 3 filter views and one week of activity history. Pro costs $5 a month billed $60 yearly and adds 300 projects, calendar and table layouts, custom reminders and deadlines. It is more expensive than TickTick Premium.

Microsoft To Do is a clean, free task app that makes the most sense if your work runs on Outlook. Microsoft's App Store listing centers on My Day, a personalized daily planner that suggests tasks from across your other lists. Tasks sync with Outlook, so emails you flag at work appear as tasks on the iPhone, and lists are stored in Microsoft 365. Personal lists can be shared with anyone, with notifications when someone adds, completes or removes a task. Each task can hold steps, notes and attachments up to 25MB, with one-time or recurring due dates. Lists can be personalized with themes, backgrounds and emoji. What it lacks is depth: there is no calendar view, no habits and no focus timer, and you need a Microsoft account. It is a calm, free choice for lists and daily planning, especially if Outlook is already your work calendar.

Structured is less a to-do list than a timeline for the day, and that is its appeal. The App Store listing describes a drag and drop day planner where every task, event and routine sits in order, with an inbox for capturing ideas and scheduling them later. The free version already includes sync across iPhone, iPad, Apple Watch and Mac, sub-tasks with notes, a Pomodoro focus timer, Live Activities, interactive widgets, color coding and accessibility features such as VoiceOver and a dyslexia-friendly font. Structured Pro connects your calendars and Apple Reminders, adds recurring tasks and routines, AI day planning, Replan for missed tasks and custom notifications. Pro is sold monthly, yearly or as a lifetime purchase, but the US App Store lists several yearly prices, so we have not quoted one. The developer reports 1.5 million active users. For people who think in hours rather than lists, it is easy to keep up.

Google Tasks is the plainest app on this list, and that suits some people. Google's App Store listing describes task lists with subtasks and details, due dates with notification reminders and drag and drop ordering. Its real strength is the link to Gmail and Google Calendar: you can turn an email into a task, see tasks in the Gmail side panel on the web, trace a task back to its source email and manage tasks created in Calendar from the iPhone. It is free with a Google Account. The listing does not mention tags, location reminders, shared lists or an Apple Watch app, and the app lists iPhone and iPad only. If your day starts in Gmail and your calendar is Google Calendar, it keeps tasks in the same place with nothing to pay. If you want an app that feels built for iOS, Things 3 or Apple Reminders fit better.

Any.do combines a task list, a calendar and a daily planner, and it leans toward households. Its App Store listing describes reminders by time or place, recurring reminders, sub-tasks, notes, attachments and voice entry, plus calendar views by day, week and month that pull in the phone's calendar, Google Calendar and Outlook. Shared lists let family members assign tasks and chat, and a grocery list can be shared so others add items in real time. You can also forward emails to do@any.do. On Any.do's pricing page the free Personal plan covers tasks, reminders, calendar and the daily planner, while Premium adds recurring tasks, WhatsApp reminders, AI features, color tags and location reminders for $4.99 a month billed annually or $7.99 monthly. A Family plan covers 4 members for $8.33 a month billed annually. The downsides are that useful basics such as recurring tasks sit behind Premium, and the App Store shows many promotional prices.

Due solves one problem better than any other app here: reminders you cannot ignore. The developer's App Store listing explains Auto Snooze, which keeps re-alerting you about a missed reminder every 1, 5, 10, 15, 30 or 60 minutes until you mark it done or reschedule it. Critical Alerts get through silent mode and Focus, and Prominent Alerts on iOS 26 ring like an alarm. Twelve customizable quick times and natural date parsing make setting and postponing fast, recurring rules handle patterns such as every third Wednesday, and countdown timers cover tasks like laundry. It has an Apple Watch app, widgets, Control Center buttons and Shortcuts. There is no account, the developer says it cannot access your reminders, and sync runs through iCloud or Dropbox. The $7.99 purchase includes every current feature and a year of new ones; an optional $4.99 annual Upgrade Pass covers later additions. Due is not a project manager, so many people pair it with Things or Reminders.

OmniFocus 4 is the deepest task manager on the iPhone and the hardest to justify for casual use. The Omni Group's App Store listing describes a unified interface across Mac, iPhone, iPad, Apple Watch and Vision Pro built around a task outline, where tasks are organized with projects, tags and dates. The Perspectives Bar, Quick Open and back and forward history help move around large lists, and the Pro tier adds Focus to show only certain projects or folders. Omni runs a free sync service with end-to-end encryption, and version 4 is sold as one universal license for every Apple device: Standard costs $74.99 and Pro $149.99 on the US App Store after a two-week free trial. That is a lot more than Things, and the app's 4.0 rating from 346 reviews is the lowest here. If you manage dozens of projects and want custom views, it is worth the trial.
