The 10 Best Reminder Apps for iPhone in 2026 (Ranked with App Store Data)
The Best Reminder Apps for iPhone, 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, and the ranking weighs whether the reminder gets you to act above how many features it has.
| # | App | US App Store (Aug 2026) | Best for | The catch |
|---|---|---|---|---|
| 1 | NagMeLater | No app, runs in WhatsApp | Reminders that arrive as messages and can nag until done, on iPhone and everything else | Needs WhatsApp (you have it) |
| 2 | Apple Reminders | Built in, 4.8★ (978K ratings) | Free, Siri, shared lists, the default for a reason | Apple devices only; one alert, then silence |
| 3 | Things 3 | $9.99, 4.8★ (28K), #1–2 paid Productivity | The most polished personal task manager on iOS | Paid per platform, Apple only, no nag |
| 4 | Todoist | Free / Pro, 4.8★ (128K) | Cross-platform power users, natural-language dates | Reminders need Pro ($6.99/mo) |
| 5 | TickTick | Free / Premium, 4.9★ (45K) | Tasks, habits, Pomodoro and calendar in one | Feature-heavy; more app than most people need |
| 6 | Microsoft To Do | Free, 4.7★ (265K) | Outlook and Windows-at-work users | Reminders stay inside the Microsoft world |
| 7 | Google Tasks | Free, 4.8★ (106K) | Gmail and Google Calendar households | Basic notifications, no nag, no natural language |
| 8 | Structured | Free / Pro, 4.8★ (164K) | Time-blocked visual day planning, ADHD-friendly | One notification per block; recurring and calendar need Pro |
| 9 | Due | $7.99, 4.7★ (2.8K), #7 paid Productivity | Auto-snooze nagging until you mark it done | Apple only, paid per platform, can only nag you |
| 10 | Finch | Free / Plus, 4.95★ (741K) | Habit and self-care streaks with a pet that grows | A game first; reminders are ordinary push alerts |
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.
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 Notification 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. Where a competitor is better than NagMeLater at something, the table says so.
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, and since iOS 17 handles grocery-list sorting and early reminders. For a lot of people it is the right answer and this whole article can stop here.
Where it 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). And its natural-language parsing is thin compared with Todoist or a chatbot. Full comparison: Apple Reminders alternative.
Things 3, Todoist and TickTick: The Serious Task Managers
Things 3 ($9.99 on iPhone, sold separately for iPad and Mac; #1 or #2 in paid Productivity most days) is the most beautifully made personal task manager on any platform. Its Today/Upcoming/Anytime structure is the model everyone else copies. It is Apple-only, one-time purchase per device, 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 at $6.99/month (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 (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 (details). Due ($7.99, #7 paid Productivity) is the opposite: a tiny app whose whole point is auto-snooze, re-alerting every minute until you mark the reminder done. It is Apple-only, bought per platform, and can only nag you (details). Finch (4.95★ from 741K ratings, the highest-rated app here) is a self-care game where completing goals feeds a bird; 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. 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. The honest catch: it needs WhatsApp, and after 7 free days it costs $1.99/month or $59 lifetime.
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.
- You want the best-designed task manager and do not mind paying: Things 3.
- You want power and cross-platform: Todoist (structure) or TickTick (everything in one).
- You plan visually or have ADHD: Structured for the plan, plus a nagger for the follow-through.
- 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 reminders that reach you as messages, on any phone, with nothing to install: NagMeLater.

Frequently Asked Questions
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. NagMeLater is free for 7 days, then $1.99/month.
Is there an iPhone reminder app that keeps nagging until I do it?
Due ($7.99, Apple only) re-alerts every minute until you mark the reminder done. 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.
Why do my iPhone reminders not show up?
Usually a Focus mode is silencing the app, or Notification Summary is holding its alerts for a scheduled digest. Check Settings, Focus, and Settings, Notifications, Scheduled Summary. Reminders that arrive as WhatsApp messages inherit whatever priority you already gave WhatsApp.
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.
