The Best Reminder App in 2026: 7 Ranked, Free and Paid
The Short Answer
The best reminder app in 2026 is the one whose reminder you actually notice, and for most people that is not one more app icon. Our pick is NagMeLater, which delivers reminders as WhatsApp messages you answer with a single word, with nothing to install. If you want a real task manager underneath the reminders, Todoist is the strongest of the app-store options (Pro is $7 a month, or $60 a year). TickTick is the best all-in-one (Premium $49.99 a year). On iPhone, Apple Reminders got materially better on September 14, 2026, when iOS 27 shipped plain-language typed reminders, although that feature needs an iPhone 15 Pro or newer. On Android the default moved out from under people: Google Keep's reminders now live in Google Tasks, and location reminders are gone. The best genuinely free pick that works on every platform is Microsoft To Do. Every price and limit below was re-checked against each company's own pages in September 2026.
| # | App | Best for | Price | The catch |
|---|---|---|---|---|
| 1 | NagMeLater | Reminders you will actually see, delivered on WhatsApp, nothing to install | 7 days free, then $4.99/mo or $99 once | Needs WhatsApp, and it is a reminder tool, not a project manager |
| 2 | Todoist | Reminders sitting on top of a proper task system: projects, labels, priorities | Free tier; Pro $7/mo or $60/yr | Free covers basic reminders; multiple custom reminders per task are Pro |
| 3 | TickTick | One app for tasks, calendar, habits and a Pomodoro timer | Free tier; Premium $49.99/yr | The free tier's caps hit reminders directly (9 lists, 2 reminders per task) |
| 4 | Apple Reminders | iPhone owners who stay inside Apple, now with plain-language input | Free | No Android app, and the iOS 27 natural-language feature needs an iPhone 15 Pro or newer |
| 5 | Microsoft To Do | The best free cross-platform pick, strongest on Windows and in Outlook | Free | Needs a Microsoft account, and reminders do not travel outside the Microsoft world |
| 6 | Google Keep | Free notes on Android, if you accept where the reminders went | Free | Its reminders are Google Tasks now, Keep no longer posts the notification, and location reminders were dropped |
| 7 | Any.do | The most polished cross-platform task app, and it does send reminders into WhatsApp | Free tier; Premium $7.99/mo or $4.99/mo yearly | The WhatsApp bot is Premium only, and the app stays the system of record |
Below: what changed this year, the test we ranked on, all seven in detail, the honest free answer, and the best pick per platform.
What Changed in 2026, and Why Two Picks Moved
Two of the seven are not the app they were when this guide was first written, and both changes land on reminders specifically.
Apple Reminders learned to read a sentence
iOS 27 arrived on September 14, 2026: Apple confirmed that date a week beforehand (AppleInsider, 9to5Mac), and Macworld covered it on the day it shipped. In it, Reminders takes a typed plain-language line such as "Remind me to go grocery shopping at 2pm on Thursday" and fills in the date, time and location itself instead of scanning for keywords you then confirm field by field (MacRumors' feature guide, 9to5Mac's Reminders rundown). That closes the single biggest gap we used to hold against it. The caveat is hardware: this is an Apple Intelligence feature, and Apple Intelligence needs an iPhone 15 Pro or newer, so an iPhone 14 on iOS 27 does not get it.
Google Keep's reminders are Google Tasks now
Google moved Keep reminders into Google Tasks starting in the second half of 2025 (Google Workspace Updates, and the help page Learn about Google Keep reminders in Google Tasks), and 9to5Google reported it reaching most accounts by January 2026. A new reminder you set in Keep is saved as a task, the notification comes from Tasks or Calendar rather than from Keep, and location-based reminders are no longer supported at all. If your "remind me when I get to the office" stopped working, that is why. The full Android picture, including install counts and the battery-optimisation problem, is in the Android roundup.
And the prices moved
Todoist raised Pro in December 2025, so it is now $7 a month or $60 a year, about $5 a month billed yearly. TickTick's Premium is $49.99 a year list, and it is often shown discounted, so check the annual offer before paying monthly. Any.do Premium is $7.99 a month, or $4.99 a month billed yearly. Nothing here is expensive; the point is that the free tiers of the paid apps tend to put reminders on the paid side, which matters when reminders are the whole reason you are choosing.
The Test We Ranked On
The best reminder app is the one you will use every time without thinking about it, and whose alert you actually see. That is three things: no friction to set one, a high read rate when it fires, and working on every device you own.
The read-rate half is not a hunch. A JAMA Internal Medicine meta-analysis of 16 randomised trials found that simple text-message reminders roughly doubled the odds of people taking their medication on time. The channel is most of the battle, which is why where a reminder arrives matters more than which app generated it.
The friction half has research behind it too. Peter Gollwitzer and Paschal Sheeran's 2006 meta-analysis of 94 studies found that forming an implementation intention, an if-then plan naming when and where you will act, raised goal attainment by a medium-to-large effect (d = 0.65) over merely intending to do the thing. A reminder is that plan made external: "Remind me on the 15th at 9am to file the GST return" fixes the when, and the message supplies the cue. An app that makes stating the when tedious, or that delivers the cue somewhere you do not look, is throwing away the mechanism that makes reminders work.
So the honest test is not the feature list. It is whether the reminder reaches you somewhere you will notice and act on it. Every pick below is judged on that.
The Seven, One by One
1. NagMeLater: reminders that arrive where you already look
You text a sentence to a WhatsApp contact and the reminder comes back as a WhatsApp message at the time you named, in whatever language you wrote it in. There is no app, no account and no notification channel to configure, because WhatsApp is already set up on your phone. When it fires you reply done or snooze 15, and nag mode will keep asking every 30 minutes up to three times until you do. It handles recurring rules, a to-do list, habit streaks and Google Calendar meeting alerts in the same chat. The honest catch: it is a reminder tool, not a project manager, and if you want boards, subtasks and team assignment you want Todoist or something bigger. Pricing is 7 days free and unlimited with no card, then $4.99 a month or $99 once.
2. Todoist: the best reminders on top of a real task system
Todoist has the best date parsing of the app-store crowd and the deepest structure: projects, sections, labels, priorities, filters. If your reminders are really tasks that need somewhere to live, this is the pick. Free (Beginner) gives you 5 personal projects and basic reminders on a dated task; multiple custom reminders per task, the calendar layout, deadlines and the AI assist features sit in Pro at $7 a month or $60 a year. Reminders being a paid feature is the thing to know before you install it for reminders (more detail, or the head-to-head).
3. TickTick: one app for everything, if you will pay for it
Tasks, a calendar, habit tracking and a Pomodoro timer in one place, and it is genuinely good at all four. Premium is $49.99 a year list price and is frequently offered at a discount. The free tier is usable but its caps land on reminders: 9 lists, 99 tasks per list, 2 reminders per task, 5 habits, and list view only in the calendar (more detail).
4. Apple Reminders: free, built in, and now reads a sentence
On an iPhone that supports Apple Intelligence, iOS 27 turned Reminders from a form into something you can type at, which is a real improvement and the reason it moved up this list. It syncs across iPhone, iPad, Mac and Watch, costs nothing, and grocery lists sort themselves. Two limits stay: there is no Android app, so the system breaks the day you switch phones, and the plain-language input needs an iPhone 15 Pro or newer (head-to-head).
5. Microsoft To Do: the best free one that works everywhere
Free with no paid tier, reminders included, on Windows, iPhone, Android and the web, with recurring due dates, shared lists and Outlook integration. If "free forever and on all my devices" is the requirement, this is the answer. It needs a Microsoft account, its reminders arrive from its own app icon, and outside the Microsoft world it feels like a visitor.
6. Google Keep: still fine for notes, no longer the reminder app
Keep is a good free notes app with over a billion installs, and for a decade it was the default Android answer to this question. It is not any more, for the reason in the section above: reminders are Google Tasks now, Keep does not post the notification, and location reminders are gone. If you like Keep, keep it for notes and let Tasks or Calendar do the nagging (head-to-head).
7. Any.do: the closest thing here to what we do
Any.do is the most polished app on this list, and it deserves a correction we made in our Android roundup: its WhatsApp integration is not capture-only. Any.do's own help centre says you can add tasks through WhatsApp and receive reminders there without opening the app. Credit where it is due. The differences are that the bot needs Premium ($7.99 a month, or $4.99 a month billed yearly), free users do not get it at all, the app remains the system of record, and there is no nag-until-done loop (more detail, head-to-head).
If what you actually want is a bot that lives inside WhatsApp rather than an app-store app, that is a different shootout: the WhatsApp reminder bots compared.
No app, no account. Save the number, send a message, done.
Which Reminder App Is Best If You Keep Ignoring Notifications?
If you swipe reminder alerts away without reading them, the fix is not a better to-do app, it is a different channel. Alireza Sahami Shirazi and colleagues analysed close to 200 million Android notifications from more than 40,000 users (CHI 2014) and found that people rated messaging-app notifications the most important of any category, 4.43 out of 5 on average and 4.53 for WhatsApp specifically, against 3.50 for calendar apps and 2.07 for alarm clocks. Speed followed importance: WhatsApp notifications were opened in a median of 15 seconds, and once any notification had sat unopened for five minutes, the chance it would ever be opened fell to 17%.
A reminder that arrives as a WhatsApp message inherits that attention. A reminder from a separate to-do app has to earn it against everything else on the screen. That is the entire thesis of our pick, and it is the one thing no amount of feature work fixes in an app you have trained yourself to ignore.
Two other levers, if you would rather stay app-based: redundancy (Todoist Pro and TickTick Premium both allow more than one reminder per task) and volume. For volume on any WhatsApp contact, including ours, open WhatsApp, go to Notifications for that chat and set a custom ringtone, including an alarm tone.
If ignoring alerts comes with evaporating thoughts and appointments that ambush you, the ranking changes, because the failure modes do. We cover them in Why Reminders Don't Work for ADHD and rank the tools against those mechanisms in the ADHD reminder app comparison.
The Best Free Reminder App: An Honest Answer
If free forever is the only criterion, the honest answer is Microsoft To Do: no paid tier, reminders included, on Windows, Mac, iPhone, Android and the web, as long as you are happy signing in with a Microsoft account. On an iPhone you already own, Apple Reminders is free and now reads a typed sentence. On Android, the free default is Google Tasks, which is where Keep's reminders went.
Two things worth knowing before you pick on price. First, "free" usually means a free tier, and the paid apps tend to put reminders on the paid side: Todoist keeps multiple custom reminders per task for Pro, TickTick's free tier allows 2 reminders per task, and Any.do's WhatsApp bot is Premium only. Second, the real cost of a reminder app is not the subscription, it is every reminder you never saw. A free app whose alerts you swipe away is more expensive than a paid one you act on.
Where we fit: your first 7 days are free and unlimited, with no signup, no card and nothing to install, which is enough to find out whether WhatsApp delivery changes anything for you. After that it is $4.99 a month or $99 once. The free WhatsApp tools and printable templates never cost anything.
The Best Reminder App by Platform
Android
The default moved this year, so this is worth re-deciding: Keep's reminders are Tasks now. Free and built in, Google Tasks or Microsoft To Do. Paid and powerful, Todoist or TickTick. No install at all, ours. Android's own machinery is the hidden variable here: battery optimisation, the Android 13 notification permission and the Android 14 exact-alarm permission all decide whether a "9:00" reminder actually lands at 9:00. The Android roundup ranks ten apps with install counts, prices and that whole problem explained.
iPhone
Apple Reminders is the right default on an iPhone 15 Pro or newer, where iOS 27's plain-language input works. On older hardware, or if you also use an Android device, the case for something else is stronger. The iPhone roundup covers Apple Reminders, Things 3, Due, Structured and Finch with App Store ratings, plus the Focus and Notification Summary settings that quietly hide reminders.
Windows
Microsoft To Do is the honest pick: free, reminders included, and native to the place you are working. Its reminders still come from a separate app, which is the thread running through this whole guide. Our alternative on Windows is not a Windows app at all: WhatsApp Desktop is, so a reminder lands on the laptop and the phone at the same moment.
| Platform | Free default | Best paid app | No install |
|---|---|---|---|
| Android | Google Tasks or Microsoft To Do | Todoist, TickTick | NagMeLater (WhatsApp) |
| iPhone | Apple Reminders | Things 3, Todoist | NagMeLater (WhatsApp) |
| Windows | Microsoft To Do | Todoist, TickTick | NagMeLater (WhatsApp Desktop) |
| Mac | Apple Reminders | Things 3 | NagMeLater (WhatsApp Desktop) |
| Both Android and iPhone | Microsoft To Do | Todoist, TickTick | NagMeLater (WhatsApp) |
Who Should Pick Which
Choose by the reason you are searching, not by the longest feature table:
- You set reminders and miss them. Change the channel before you change the app. That is our case in one line.
- You want a system, not just alerts. Todoist, or TickTick if you want the calendar and habits in the same place.
- You want free forever on every device. Microsoft To Do.
- You live entirely on Apple hardware, new enough for Apple Intelligence. Apple Reminders, and you are done.
- You switch between Android and iPhone. Anything cross-platform, which rules out Apple Reminders and makes WhatsApp delivery the least breakable option.
- You write in Hindi, Gujarati, Spanish or anything that is not English. Plain-language parsing in your own language is rare in app-store apps; ours reads the sentence you actually typed (Hindi guide).
- You need recurring professional deadlines. GST returns, invoices, client callbacks, medication: any of these apps can do it, and the deciding factor is whether you will see the alert on the day.
Not sure what to set first? The Reminder Library has one-tap setups for the common ones: birthdays, credit card bills, daily medicine, drinking water, and a hundred more.
Frequently Asked Questions
What is the best reminder app in 2026?
Judged on whether the reminder actually gets you to act, the best reminder app is one that delivers where you already read messages, which is why NagMeLater is our pick: you text a WhatsApp contact in plain language and the reminder comes back as a WhatsApp message you answer with one word, with nothing to install. If you want a full task system underneath, Todoist is the strongest app-store option at $7 a month or $60 a year, and TickTick is the best all-in-one at $49.99 a year. Apple Reminders is the best free pick on a recent iPhone, and Microsoft To Do is the best free pick that works on every platform.
What is the best free reminder app?
Microsoft To Do is the best genuinely free reminder app: it has no paid tier, includes reminders, and runs on Windows, Mac, iPhone, Android and the web with a Microsoft account. On an iPhone, Apple Reminders is free and, since iOS 27, understands a typed plain-language reminder on an iPhone 15 Pro or newer. On Android the free default is Google Tasks, which is where Google Keep's reminders were moved. NagMeLater is free and unlimited for 7 days with no card, then $4.99 a month or $99 once.
Does Apple Reminders understand natural language now?
Yes, as of iOS 27, which was released on September 14, 2026. You can type a line such as 'Remind me to go grocery shopping at 2pm on Thursday' and Reminders fills in the date, time and location itself rather than asking you to confirm each field. It is an Apple Intelligence feature, so it requires an iPhone 15 Pro or newer; an older iPhone running iOS 27 keeps the previous keyword-based behaviour.
Why did my Google Keep reminders stop working?
Google moved Keep reminders into Google Tasks starting in the second half of 2025, and the migration reached most accounts by January 2026. A reminder set in Keep is now saved as a task, the notification comes from Tasks or Calendar instead of Keep, and location-based reminders are no longer supported at all, so a 'remind me when I arrive' reminder cannot be recreated. Your old reminders were moved rather than deleted.
What is the best reminder app for Android?
For free and built in, Google Tasks or Microsoft To Do; for paid and powerful, Todoist or TickTick; and for no install at all, NagMeLater through WhatsApp. On Android the bigger risk is the phone rather than the app: battery optimisation, the Android 13 notification permission and the Android 14 exact-alarm permission all decide whether an alert fires on the minute. Our Android roundup ranks ten apps with prices and explains those settings.
What is the best reminder app for iPhone?
Apple Reminders is the right default on an iPhone 15 Pro or newer, where the iOS 27 plain-language input works and everything syncs with iPad, Mac and Watch for free. On older iPhones, or if you also use an Android phone, a cross-platform option is safer: Things 3 and Todoist are the strongest apps, and NagMeLater needs no App Store download because it arrives through WhatsApp.
Which reminder app has the best notifications?
The most effective notification is one you have not trained yourself to dismiss. In a University of Stuttgart study of nearly 200 million Android notifications, messaging apps were rated the most important category, 4.53 out of 5 for WhatsApp specifically against 3.50 for calendar apps and 2.07 for alarm clocks, and WhatsApp notifications were opened in a median of 15 seconds. That is why a reminder delivered as a WhatsApp message tends to get acted on, while an alert from a separate to-do app competes with everything else on the screen.
Is there a reminder app that works on both Android and iPhone?
Yes. Todoist, TickTick and Microsoft To Do all run on both, and NagMeLater works on both without an install because it delivers through WhatsApp, so moving from Android to iPhone changes nothing about your reminders. Apple Reminders is the notable exception: it has no Android app, so an Apple-only setup breaks the day you switch phones.
