The 10 Best Reminder Apps for Android in 2026 (Ranked by Real Install Counts)
The Best Reminder Apps for Android, Ranked
There are hundreds of reminder apps on Google Play. Most "best of" lists pick ten at random. This one starts from what Android users actually install: every entry below carries its Play Store install band, rating and review count as of August 2026, pulled from the store listing, and the ranking weighs one thing above features: does the reminder reach you and get you to act?
| # | App | Play Store (Aug 2026) | Best for | The catch |
|---|---|---|---|---|
| 1 | NagMeLater | No app, runs in WhatsApp | Reminders you actually see, on any Android, no install | Needs WhatsApp (you have it) |
| 2 | Google Keep | 1B+ installs, 4.7★ (2.5M reviews) | Free notes with reminders attached, on every Android | Reminders are a feature of a note; push only |
| 3 | Google Tasks | 10M+, 4.6★ (597K) | Free, minimal, lives inside Gmail and Calendar | Basic notifications, no nag, no natural language |
| 4 | Microsoft To Do | 10M+, 4.6★ (479K) | Outlook and Microsoft 365 users, free | Reminders stay inside the Microsoft world |
| 5 | Todoist | 10M+, 4.6★ (303K) | Power users: projects, labels, natural-language dates | Reminders and calendar need Pro ($6.99/mo) |
| 6 | TickTick | 10M+, 4.6★ (163K) | Tasks, habits, Pomodoro and calendar in one app | Feature-heavy; more app than most people need |
| 7 | Any.do | 10M+, 4.4★ (505K) | Polished lists with a WhatsApp capture bot | WhatsApp capture is Premium and one-way |
| 8 | To Do List (SplenDO) | 10M+, 4.6★ (948K) | Simple lists, voice input, Google Tasks sync | Ads in the free tier, dated design |
| 9 | Tasks (Pocket Brilliance) | 5M+, 4.8★ (137K) | Ad-free, private, clean recurring reminders | Android only, sync is limited |
| 10 | Loop Habit Tracker | 5M+, 4.7★ (63K) | Free, open-source habit streaks | Habits only, no sync, notifications need a battery exemption |
Two Android-specific notes before the details. Samsung Reminder, preinstalled on every Galaxy, is not on this list because it is not on Google Play at all: it ships through the Galaxy Store and does not survive a move to a Pixel or a OnePlus (see our Samsung Reminder alternative page). And ColorNote (100M+ installs, 4.9★ from 3.96M reviews) is the most-installed third-party app that can set reminders, but it is a sticky-notes app first, so it sits with Google Keep in spirit rather than as a separate pick.
How We Ranked Them
Three questions, in order. Does the reminder get seen? A notification from an app you open weekly is easy to swipe; a message from a contact is not. Does it survive Android? The platform itself is the biggest reason reminders fail on Android (next section). How much friction to set one? Typing "remind me tomorrow at 9 to call the bank" beats five taps through a date picker every time.
Install counts and ratings decide ties, and they are the honest signal of what people keep on their phones. Where a competitor does something better than NagMeLater, the table says so.
Why Reminders Fail on Android (and What to Do About It)
This is the section other roundups skip. Three platform behaviours quietly break reminder apps on Android:
- Battery optimisation. Several manufacturers suspend background apps aggressively to extend battery life. A local reminder that depends on the app being alive is delayed or dropped unless you exempt the app in settings, and the exemption sometimes resets after an update. The community project Don't Kill My App ranks brands by how badly they do this; it is the first place to look if a reminder "never fired".
- Notification permission. Since Android 13, apps must ask for permission before they can post notifications at all (Android developer documentation). Tap "Don't allow" once during onboarding and every reminder from that app is silently discarded.
- Exact alarms. From Android 14, the permission apps use to fire at an exact minute is denied by default for most newly installed apps (Android 14 behaviour changes). Well-built apps ask for it; many do not, and their "9:00" reminder becomes "sometime around nine".
Every app in the table that fires local notifications, which is all of them except NagMeLater, is exposed to some of this. The workaround is the same for each: allow notifications, grant exact alarms if asked, and add the app to the battery-optimisation exemption list. Or use a reminder that arrives as a WhatsApp message, because WhatsApp is the one app nobody's phone is allowed to kill.
Google Keep and Google Tasks: Free and Already on Your Phone
Google Keep (1B+ installs, 4.7★) is the most-installed reminder-capable app on Android because it is on almost every phone out of the box. A reminder is a bell on a note: pick a time or a place, and Keep posts a notification. It is free, syncs through your Google account, and does location reminders, which nothing else on this list except Samsung does well. The catch is that reminders are second-class: you need a note to hang one on, recurrence is basic, and the alert is a push notification competing with everything else. Full comparison: Google Keep alternative.
Google Tasks (10M+, 4.6★) is the opposite shape: a plain to-do list living in the Gmail and Calendar side panels. It is the right pick if you already run your life in Google Calendar and just want tasks next to it. It has no natural-language input, no nag, and its notifications are as easy to lose as anyone's. Details: Google Tasks alternative.
Microsoft To Do, Todoist, TickTick, Any.do: The Full Task Managers
These four are the mainstream cross-platform task apps, all in the 10M+ band on Play with 4.4 to 4.6 stars.
Microsoft To Do is free, clean, and the natural choice if your work lives in Outlook; My Day and shared lists are excellent. Its reminders do not travel well outside Microsoft's world (details). Todoist has the best natural-language date parsing of the app-store crowd and the deepest project structure, but reminders and calendar sync sit behind Pro at $6.99/month (details). TickTick bundles tasks, habits, a Pomodoro timer and a calendar into one app with a generous free tier; if you want one app to do everything, this is it (details). Any.do is the most polished to look at and the only one with a WhatsApp bot, but the bot only captures tasks into the app, it never sends the reminder back to WhatsApp, and it needs Premium (details).
The pattern across all four: excellent at organising, ordinary at reminding. Each fires a single push notification from an app you have to remember to open.
SplenDO, Tasks and Loop: The Android-Native Favourites
Three apps that rarely appear on cross-platform lists because they are Android-first, yet Android users have voted for them in volume.
To Do List by SplenDO (10M+, 4.6★ from 948K reviews, the most-reviewed third-party to-do app on Play) is the classic simple list: voice input, home-screen widgets, two-way Google Tasks sync. The free tier carries ads and the design has not changed much in years, but it is dependable. Tasks by Pocket Brilliance (5M+, 4.8★) is the ad-free, privacy-first alternative with proper recurring reminders and a calendar view; its limits are that it is Android-only and sync is limited. Loop Habit Tracker (5M+, 4.7★) is free, open source, has no ads and no account, and its streak graphs and widgets are the best in the category. It is habits only, stores everything on the device with no sync, and its reminders are exactly the kind that battery optimisers kill (Loop alternative).
The One That Needs No App: NagMeLater
NagMeLater is not on the Play Store because it does not need to be. It is a WhatsApp contact: message it "remind me tomorrow at 9am to call the bank" and at 9am tomorrow a WhatsApp message arrives saying exactly that. Recurring reminders ("every Monday at 8am"), habits with streaks ("habit: run at 7am daily"), to-dos, notes, and a nag mode that re-sends every 30 minutes until you reply done all work the same way, in English, Hindi, Hinglish or thirty-odd other languages.
On Android specifically, this sidesteps every failure mode above. There is no notification permission to grant, no exact-alarm setting, and no battery exemption, because WhatsApp already has all three on every phone. It also follows you across brands: switch from a Galaxy to a Pixel and every reminder is still there. The honest catch is that it needs WhatsApp and it is not free forever: 7 days unlimited, then $1.99/month or $59 lifetime.
No app, no account. Save the number, send a message, done.
Which One Should You Pick?
- You want free and already-installed: Google Keep for notes-with-reminders, Google Tasks if you live in Calendar.
- You want a real task manager: Todoist for structure, TickTick for everything-in-one, Microsoft To Do if you work in Outlook.
- You want simple, Android-native, no account: Tasks (ad-free) or SplenDO (ads, more reviews).
- You want habit streaks: Loop if you are fine with local-only; NagMeLater if you want the reminder to arrive regardless of your phone's battery settings.
- You want the reminder to actually reach you, on any phone, with nothing to install: NagMeLater.

Frequently Asked Questions
What is the best free reminder app for Android?
Google Keep if you want notes with reminders attached, Google Tasks if you want a plain list inside Gmail and Calendar, and Tasks by Pocket Brilliance if you want a dedicated ad-free reminder app. All three are free. NagMeLater is free for 7 days, then $1.99/month.
Why do my Android reminders not go off?
Three usual causes: the app was denied notification permission (required since Android 13), the app was not granted exact-alarm permission (denied by default for most apps since Android 14), or the phone's battery optimisation suspended the app. Fix all three in Settings, or use a reminder that arrives as a WhatsApp message, which is never throttled.
Is there a reminder app for Android that works without installing anything?
Yes. NagMeLater runs entirely inside WhatsApp: save the number, send a message like 'remind me at 5pm to call mom', and the reminder arrives as a WhatsApp message. No Play Store install, no account.
What is the most downloaded reminder app on Android?
Google Keep, at over one billion installs, because it is preinstalled on most Android phones. Among dedicated to-do apps, To Do List by SplenDO has the most Play Store reviews (about 948K), with Google Tasks, Any.do and Microsoft To Do close behind, all in the 10M+ install band (Play Store, August 2026).
Does Samsung Reminder work on non-Samsung phones?
No. It is distributed through the Galaxy Store only and syncs via a Samsung account. If you switch to a Pixel or iPhone, Samsung's supported route is syncing to Microsoft To Do; a WhatsApp reminder bot like NagMeLater works on both the old and the new phone with nothing to migrate.
Which Android reminder app nags you until you do the task?
Very few app-store reminders re-nag. NagMeLater has a nag mode ('nag mode on', or add 'and nag me until done' to a reminder) that re-sends the WhatsApp message every 30 minutes, up to three times, until you reply done or snooze.
