Best Reminder App for iPhone in 2026: 10 iPhone Reminder Apps Ranked
The Short Answer
For most people the best reminder app for iPhone is Apple Reminders, which is free and already installed; Things 3 is the best-made alternative, Due is the one that keeps nagging, and the best reminder of all is the one that arrives somewhere you already look. Apple Reminders got materially better this month: iOS 27 shipped on 14 September 2026 and Reminders now takes plain-language input like "remind me to go grocery shopping at 2pm on Thursday", which used to be a reason to pay for Todoist. What it still does is fire a single banner. If a Focus mode is silencing notifications, or Scheduled Summary is holding them for a digest, that banner is late or invisible, and one swipe ends it. That gap is what the rest of this list fills: either with persistence, like Due re-alerting until you tick the task off, or by delivering the reminder as a message you can reply to rather than a notification you dismiss.
The Best iPhone Reminder Apps, Ranked
iPhone comes with a very good reminder app, so any list of "best reminder apps for iPhone" has to answer one question honestly: what does this do that Apple Reminders does not? Every entry below carries its US App Store rating, review count and, where relevant, chart position as of August 2026, plus a price re-checked on 23 September 2026, and the ranking weighs whether the reminder gets you to act above how many features it has.
| # | App | US App Store (Aug 2026) | Price (Sep 2026) | Best for | The catch |
|---|---|---|---|---|---|
| 1 | NagMeLater | No app, runs in WhatsApp | 7 days free, then $4.99/mo or $99 once | Reminders that arrive as messages and can nag until done, on iPhone and everything else | Needs WhatsApp (you have it); not free forever |
| 2 | Apple Reminders | Built in, 4.8★ (978K ratings) | Free with iOS | Free, Siri, shared lists, and plain-language input since iOS 27 | Apple devices only; one alert, then silence |
| 3 | Things 3 | 4.8★ (28K), #1 or #2 paid Productivity | $9.99 iPhone, $19.99 iPad, $49.99 Mac, one-time | The most polished personal task manager on iOS | Bought once per platform, Apple only, no nag |
| 4 | Todoist | Free / Pro, 4.8★ (128K) | Free tier; Pro $7/mo or $60/yr | Cross-platform power users, natural-language dates | Reminders are a Pro feature |
| 5 | TickTick | Free / Premium, 4.9★ (45K) | Free tier; Premium $35.99/yr, an offer against a $49.99 list price | Tasks, habits, Pomodoro and calendar in one | Free tier caps you at 2 reminders per task |
| 6 | Microsoft To Do | Free, 4.7★ (265K) | Free with a Microsoft account | Outlook and Windows-at-work users | Reminders stay inside the Microsoft world |
| 7 | Google Tasks | Free, 4.8★ (106K) | Free with a Google account | Gmail and Google Calendar households | Basic notifications, no nag, no natural language |
| 8 | Structured | Free / Pro, 4.8★ (164K) | Free tier; Pro is a subscription priced per region | Time-blocked visual day planning, ADHD-friendly | One notification per block; recurring and calendar need Pro |
| 9 | Due | 4.7★ (2.8K), #7 paid Productivity | $7.99 once, plus an optional Upgrade Pass for later features | Auto-snooze nagging until you mark it done | Apple only, bought per platform, can only nag you |
| 10 | Finch | Free / Plus, 4.95★ (741K) | Free; Finch Plus $9.99/mo or $69.99/yr | Habit and self-care streaks with a pet that grows | A game first; reminders are ordinary push alerts |
Prices re-checked on 23 September 2026 against each company's own pricing page, help centre or App Store listing. Structured publishes no single figure (it prices Pro by region), so this table says so rather than repeating a number from another roundup. App Store ratings, review counts and chart positions are from the US store in August 2026.
A note on what is missing. Fantastical (4.2★, calendar-first), OmniFocus (GTD power tool, small audience), Streaks (#1 paid Health & Fitness, habits only, 24-task cap) and Tiimo (Apple's iPhone App of the Year 2025, a neurodivergent-first planner) are all good, and all narrower than the ten above. Notion, Evernote and Trello can set reminders but are notes and boards first.
What iOS 27 Changed (and What It Did Not)
This section is dated on purpose, because the answer changed nine days before this update. iOS 27 was released on 14 September 2026 (MacRumors, Macworld), and Reminders was one of the apps it touched.
- Reminders takes plain language now. You can type "Remind me to go grocery shopping at 2pm on Thursday" into Reminders or Calendar and it sets the right thing, and the metadata options moved into a box around the reminder you are editing (MacRumors, 9to5Mac). If "Apple Reminders cannot parse a sentence" was your reason for paying for a task app, re-check that reason.
- The rebuilt Siri is not all there yet. The version of Siri AI that would let you create a reminder from anywhere on the device without opening the app was not available at the iOS 27 launch, even on eligible iPhones. Treat it as coming, not shipped.
- The iOS 26 Apple Intelligence features carried over. Reminders can suggest tasks from content you share to it, such as action items from a mail message or ingredients from a recipe in Safari, and it can auto-categorise a long list into sections (Apple Support). These need an Apple Intelligence-capable iPhone, which means iPhone 15 Pro, iPhone 16 or later.
What did not change is the delivery. A reminder is still one notification, subject to Focus and Scheduled Summary, and nothing in iOS 27 makes it nag you a second time. That is the next section, and it is the reason this list is ordered the way it is.
How We Ranked Them
Same three questions as our Android ranking: does the reminder get seen, does it survive the platform, and how much friction to set one? On iPhone the platform question is different. Nothing kills apps in the background the way some Android skins do, but Focus modes and Scheduled Summary quietly delay or hide alerts, and one swiped banner is the end of most reminders. Persistence, whether the app keeps nagging, therefore counts for more here than on Android.
Review counts and paid-chart positions break ties. Every price was re-checked for this update, and two of our own figures moved: TickTick's annual plan is being sold at $35.99 rather than the $49.99 list price, and Due's $7.99 purchase now sits beside an optional Upgrade Pass subscription for features added more than a year after you buy. Where a competitor is better than NagMeLater at something, the table says so, and four of the ten are free forever while we are not.
Why iPhone Reminders Get Missed (Focus and Scheduled Summary)
Android eats reminders by suspending apps. iPhone does something subtler: it delivers the notification, on time, into a place you are not looking.
- Focus modes. A Focus lets you allow or silence notifications per app, and a reminder from a silenced app waits in Notification Centre instead of interrupting you (Apple Support). Work Focus at 9am is the single most common reason a 9am reminder "never fired".
- Scheduled Summary. Settings, Notifications, Scheduled Summary batches chosen apps into a digest delivered at times you pick (Apple Support). A reminder app in the summary is by definition a reminder that arrives at the wrong time. This is separate from the Apple Intelligence feature that rewrites notification text into a summary line (Apple Support), which came back with iOS 26 and can also flatten a reminder into something easy to skim past.
- One banner, one swipe. Most of the apps here post a single notification per reminder. Dismiss it on the lock screen while you are doing something else and the app has done its whole job, correctly, and you have still forgotten.
Two fixes. Either allow your reminder app through every Focus you use and keep it out of Scheduled Summary, or pick something that repeats itself: Due re-alerts on iPhone, and a WhatsApp message inherits whatever priority you already gave WhatsApp, which for most people is the highest one on the phone.
Apple Reminders: The Default, and Why It Is Hard to Beat
Apple Reminders (4.8★ from 978K US ratings) is free, preinstalled, syncs across iPhone, iPad, Mac and Watch, takes Siri dictation, supports shared lists, location triggers, tags and smart lists, sorts a grocery list by aisle, and since iOS 27 reads a typed sentence like "remind me to go grocery shopping at 2pm on Thursday". For a lot of people it is the right answer and this whole article can stop here. We had "thin natural-language parsing" listed as its weakness in the last version of this page; as of September 2026 that is out of date, and it is the clearest reason to re-check the app before paying for another one.
Where it still falls short is exactly where the rest of the list earns its place. It is Apple-only, so a partner or parent on Android cannot share your lists. Its notification is a single banner; if a Focus mode silences it or you swipe it away, it is gone (Apple: allow or silence notifications for a Focus). It never asks you again, and it cannot remind anybody else. Full comparison: Apple Reminders alternative.
Things 3, Todoist and TickTick: The Serious Task Managers
Things 3 is the most beautifully made personal task manager on any platform, and it sits at #1 or #2 in paid Productivity most days. Its Today/Upcoming/Anytime structure is the model everyone else copies. It is bought outright, once per platform: $9.99 for iPhone and Apple Watch, $19.99 for iPad, $49.99 for Mac, with Things Cloud sync included rather than sold as a subscription (Cultured Code's pricing page). There is no Things 4: Cultured Code is still shipping updates to Things 3. It is Apple-only, and its reminders are ordinary notifications with no nag (details).
Todoist (4.8★, 128K US ratings) is the cross-platform pick: type "pay rent every 1st at 9am" and it understands, and it runs on every device you own. Reminders and calendar sync require Pro, which is $7 a month, or $60 a year, about $5 a month billed yearly, after the increase that took effect in December 2025 (details).
TickTick (4.9★, 45K) is the highest-rated of the three and bundles habits, a Pomodoro timer and a calendar; if you want one app for all of it, TickTick is the one. Its upgrade page is currently selling Premium at $35.99 a year, labelled a limited offer against a $49.99 list price, so treat $49.99 as what you may pay at renewal. The free tier is usable but capped, and one of the caps is reminders: 9 lists, 99 tasks per list and 2 reminders per task (details).
Microsoft To Do and Google Tasks: Free and Cross-Platform
Both are free, both are on iPhone and Android, and both are the right choice if your work already lives in their ecosystem. Microsoft To Do (4.7★, 265K) inherits Wunderlist's DNA and integrates with Outlook tasks; it is the best free option for people on Windows at work and iPhone at home (details). Google Tasks (4.8★, 106K) is a plain list next to Gmail and Google Calendar; minimal by design, no nag, no natural language (details).
Structured, Due and Finch: The iPhone Specialists
These three are what makes the iPhone list different from the Android one. Each is loved on the App Store and each does one thing Apple Reminders does not.
Structured (4.8★, 164K, #63 free Productivity) turns your day into a time-blocked timeline, which is why it is so often recommended for ADHD and time blindness. It is a planner, not a nagger: each block sends one notification, and recurring tasks and calendar sync are Pro features. We are not quoting a price for Pro, because Structured does not publish one figure: its own documentation says the price depends on your region and currency and tells you to check your app store, and the third-party roundups quoting it disagree with each other (Structured on its pricing, our comparison).
Due (#7 paid Productivity) is the opposite kind of app: a small one whose whole point is auto-snooze, re-alerting at an interval you choose, as often as every minute, until you mark the reminder done or reschedule it. It is $7.99 on the App Store, with an optional Upgrade Pass subscription if you want features added more than a year after your purchase. It is Apple-only, bought per platform, and it can only nag you, never anybody else (details).
Finch (4.95★ from 741K ratings, the highest-rated app here) is a self-care game where completing goals feeds a bird. The app is free, including the journalling and goal tracking most people come for; Finch Plus is $9.99 a month or $69.99 a year and mostly buys cosmetics and extras. It is wonderful for building habits, less good the day the game stops being fun, and its reminders are ordinary push alerts (details).
The One That Needs No App: NagMeLater
NagMeLater is a WhatsApp contact rather than an App Store download. Message it "remind me tomorrow at 9am to call the bank" and a WhatsApp message arrives at 9am tomorrow. Recurring reminders, habit streaks, to-dos, notes and group reminders for family all work by typing a sentence, in English, Hindi, Hinglish and dozens of other languages, and its nag mode re-sends every 30 minutes until you reply done.
On iPhone the practical differences are these. The reminder arrives as a WhatsApp message, so it gets whatever priority you already gave WhatsApp in your Focus settings, and it sits in the chat rather than vanishing when swiped. There is nothing to install on a phone with no storage left, and no Scheduled Summary exception to remember. It works identically on your partner's Android, your work phone and WhatsApp on the Mac. And it can nag other people: "remind @Mom sunday 5pm to take the tablets" lands on her phone, which no app on this list can do for someone outside its own ecosystem. The honest catch: it needs WhatsApp, and after 7 free days it costs $4.99/month or $99 lifetime, while Apple Reminders is free and already on your phone.
No app, no account. Save the number, send a message, done.
Which One Should You Pick?
- You are all-Apple and want free: Apple Reminders. Seriously, and more so since iOS 27 taught it to read a typed sentence.
- You want the best-designed task manager and do not mind paying: Things 3, at $9.99 for the iPhone app.
- You want power and cross-platform: Todoist for structure at $7 a month, TickTick for everything in one at $35.99 a year on its current offer.
- You want free and cross-platform because work lives elsewhere: Microsoft To Do for Outlook, Google Tasks for Gmail and Google Calendar.
- You plan visually or have ADHD: Structured for the plan, plus a nagger for the follow-through, because a timeline does not chase you.
- You want to be nagged until you act: Due if you are Apple-only, NagMeLater if you also have Android in your life or want to nag someone else.
- You want habit streaks and enjoy the game: Finch, free, with Finch Plus optional.
- You want reminders that reach you as messages, on any phone, with nothing to install: NagMeLater.

Frequently Asked Questions
What is the best reminder app for iPhone?
Apple Reminders, for most people. It is free, already installed, syncs to iPad, Mac and Watch, and since iOS 27 it understands a typed sentence like 'remind me to go grocery shopping at 2pm on Thursday'. Pay for something else when you want a specific thing it does not do: Things 3 ($9.99) for the best design, Todoist ($7 a month) for cross-platform structure, TickTick for habits and a calendar in one app, Due ($7.99) to be re-alerted until you tick the task off, or NagMeLater if you want the reminder to arrive as a WhatsApp message you can reply to and to be able to nag someone else.
What is the best free reminder app for iPhone?
Apple Reminders. It is preinstalled, syncs across Apple devices, works with Siri and supports shared lists. Microsoft To Do and Google Tasks are the free cross-platform options, and Finch is free if you want habit streaks with a game attached. NagMeLater is free for 7 days, then $4.99 a month or $99 once.
Does Apple Reminders understand natural language?
Yes, since iOS 27, which was released on 14 September 2026. You can type something like 'Remind me to go grocery shopping at 2pm on Thursday' into Reminders or Calendar and it sets the right date and time. On an Apple Intelligence-capable iPhone (15 Pro, 16 or later) it can also suggest reminders from content you share to it and sort a long list into categories. The rebuilt Siri that would create reminders from anywhere on the device was not available at the iOS 27 launch.
Is there an iPhone reminder app that keeps nagging until I do it?
Due ($7.99, Apple only) re-alerts at an interval you choose, as often as every minute, until you mark the reminder done or reschedule it. NagMeLater's nag mode re-sends the WhatsApp message every 30 minutes, up to three times, until you reply done or snooze, and works on Android too. Apple Reminders fires once and stops.
Why do my iPhone reminders not show up?
Usually a Focus mode is silencing the app, or Scheduled Summary is holding its alerts for a digest delivered later. Check Settings, Focus, and Settings, Notifications, Scheduled Summary. On an Apple Intelligence iPhone, notification summaries can also compress a reminder into a line that is easy to skim past. Reminders that arrive as WhatsApp messages inherit whatever priority you already gave WhatsApp.
How much does Things 3 cost on iPhone?
$9.99 as a one-time purchase, which covers iPhone and Apple Watch. The iPad app is $19.99 and the Mac app is $49.99, bought separately, and Things Cloud sync is included rather than sold as a subscription. There is no Things 4; Cultured Code is still updating Things 3.
What is the highest-rated reminder app on the App Store?
By average rating with a large sample, Finch (4.95 stars from about 741K US ratings, August 2026), though it is a self-care habit game rather than a plain reminder app. Among classic reminder apps, TickTick (4.86) and Apple Reminders (4.83, 978K ratings) lead.
Which iPhone reminder app also works on Android?
Todoist, TickTick, Microsoft To Do, Google Tasks, Any.do and Finch all have Android apps. Apple Reminders, Things 3, Due and Structured (in any complete form) do not. NagMeLater runs in WhatsApp, so it is the same on both.
Can I set a reminder on iPhone without installing anything?
Yes, two ways: Apple Reminders is already installed, or message NagMeLater on WhatsApp with 'remind me at 5pm to call mom' and the reminder arrives as a WhatsApp message.
