Best Reminder Apps to Stay on Top of Tasks
Reminder apps get a bad rap for being interchangeable — just alerts with a different logo slapped on. But get past the surface, and each one solves the “did I forget?” problem in a genuinely different way. That’s why we love putting reminder apps side by side: it turns “which one is best” from a vague question into something you can actually see.
As the team behind Planfix’s workflow tools, we test productivity and reminder software every week — not for fun, but because our own work depends on getting this right. We’ve picked our favorites to share here, tested against real recurring tasks, not marketing pages. We also looked at what actual users report on G2 and Capterra, and the pattern held up.
At a Glance: Top Reminder Apps Compared
We tested each app the same way: set a recurring reminder, assign it to someone else where possible, and see whether it actually gets noticed. Here’s how they stacked up.
| Rank | App | Best For | Platforms | Free Plan | Starting Paid Price |
| 1 | Planfix | Teams & work-related reminders | Web, iOS, Android | Yes | Starting at $8/user/month |
| 2 | Todoist | Personal task + reminder management | Web, iOS, Android, Windows, Mac | Yes, but no reminders on free tier | Pro from $5/month |
| 3 | TickTick | Reminders + habit tracking | Web, iOS, Android, Windows, Mac | Yes | Premium from $49.9/year |
| 4 | Microsoft To Do | Free reminders on Windows | Windows, Web, iOS, Android | Yes | Free (bundled with Microsoft 365 for extras) |
| 5 | Google Keep / Tasks | Simple, free Android reminders | Android, Web, iOS | Yes | Free |
| 6 | Apple Reminders | Built-in iPhone and Mac reminders | iOS, macOS, Web | Yes | Free |
| 7 | Any.do | Shared and family reminders | Web, iOS, Android | Yes | Premium from $4.99/mo (annual) |
| 8 | Things 3 | Premium one-time purchase | iOS, macOS, iPadOS | No | From $9.99 (iPhone) to $49.99 (Mac), one-time |
| 9 | Remember The Milk | Email and IM-based reminders | Web, iOS, Android | Yes, but reminders require Pro | Pro from $49.9/year |
| 10 | Due | Persistent, repeating reminders | iOS, macOS | No | One-time purchase, $9.99 on iOS |
That table is the short version — enough to point you toward the right app if you already know what you’re solving for. The reviews below go deeper into why each one landed where it did, including where a free plan is genuinely enough and where it starts to fall short once reminders stop being just personal.
What Is a Reminder App?
A reminder app is software that alerts you at a set time, place, or trigger about something you’d otherwise forget. Some tools are purely alert-based: set a time, get a notification, done. Others are full task managers with reminders layered on top, useful when you’re tracking due dates alongside longer to-do lists.
A third category goes further — notification programs built into work platforms, where an alert is tied to a task, a client, or a workflow step, and it can notify someone other than you. This is the model behind project and task management for small business tools, where reminders are one piece of a larger system rather than the whole product.
How We Evaluated These Reminder Apps
We evaluated each app using the same core reminder scenarios to make the comparison as consistent as possible. For each tool, we looked at how easy it was to create a recurring reminder, whether notifications could be assigned to other people, which notification channels were available, and how well the app worked across supported devices.
We also considered the features that matter most for different types of users, including the usefulness of the free plan, recurring reminder flexibility, team and assignment capabilities, and overall platform coverage.
Our evaluation criteria were:
- Reliability of notifications across push, email, SMS, and chat — a notification that’s easy to miss doesn’t count
- Flexibility of recurring reminders — daily, weekly, custom intervals, or process-based triggers
- Cross-device sync speed and consistency — a message set on one device should show up everywhere immediately
- Team and assignment features — can it remind someone else, not just you, and can they see it too?
- How usable the free plan actually is — not just whether one exists, but whether reminders work on it
- Platform coverage across Android, iOS, Windows, Mac, and web
We ranked each app according to what it is designed to do. A personal reminder app isn’t penalized for lacking team workflows, just as a team task management platform shouldn’t be expected to be the simplest option for a grocery list.
Best Reminder Apps
Here’s the full reminder apps breakdown, starting with our top pick.
1. Planfix

Planfix isn’t built as a standalone reminder app, and that’s the point. Alerts attach directly to a task, a contact, a deal, or a calendar event, so the alert carries context instead of arriving as a bare notification. You can set reminders in Planfix that notify a specific colleague — the assignee, a manager, or anyone watching that task — not just yourself.
Recurring reminders can repeat on custom schedules, and delivery spans the browser, email, mobile app, and Telegram through Planfix’s notification channels. A reminders panel and calendar keep everything visible at a glance, which matters when several people share responsibility for one deadline.
Reminders can also sit alongside broader task management and CRM functionality, so a message about a client renewal can stay connected to the underlying work instead of becoming a separate notification to remember.

Planfix is overkill if you just want to remember to buy milk. It’s built for people managing real work — task management software with reminders as one piece of a larger system, not the whole product.

10. Due

Source: https://www.dueapp.com/
Due is built around one idea: reminders that keep nagging until you actually deal with them. For time-sensitive tasks, it’s one of the strongest app options for daily reminders on iOS, auto-snoozing and re-alerting at intervals you choose until you respond.
Ratings:
- App Store: 4.7 / 5
Key features:
- Persistent reminders: Continue reminding you until you take action.
- Repeating reminders: Set alerts to repeat automatically.
- Quick entry: Create reminders without building a complex task system.
- Focused reminder experience: Prioritizes notifications rather than broader project management.
Pros:
- Strong focus on persistent reminders.
- Useful for tasks that are easy to forget.
- Repeating alerts can help prevent missed follow-ups.
- Simple compared with full project-management platforms.
Cons:
- No free plan.
- Limited compared with full-featured task and project-management apps.
- Primarily suited to personal reminders.
Pricing:
- One-time purchase, from approximately $9.99 on iOS.
Best for:
- People who frequently dismiss or forget standard notifications.
- Users who need persistent, repeating reminders.
- Anyone who wants a dedicated reminder tool rather than a complete task manager.
Testing all ten side by side surfaced something worth knowing upfront: the app itself rarely causes a missed reminder. Every tool here delivers notifications reliably. What varies is what happens after the notification lands.
Some apps send one alert and move on, treating the reminder as done once it’s been shown. Others keep resurfacing it until it’s actually addressed.
Neither approach is universally better — a single alert works fine for a low-stakes task, while a persistent one matters more for something that genuinely can’t slip. Which one you need depends less on the app and more on what you’re actually trying not to forget.
Best Reminder App by Category
Not every reminder app fits neatly into a “best overall” ranking — the right pick often comes down to the one thing you need it to do. Here’s how the list breaks down by use case, so you can jump straight to the app built for your situation.
- Best for teams: Planfix — reminders tied to tasks, contacts, and workflows
- Best free app overall: Microsoft To Do / Google Tasks — no paywall on core reminders
- Best reminder application for Android: Google Tasks — pre-installed, syncs with Gmail and Calendar
- Best reminders application for Windows: Microsoft To Do — native Outlook integration
- Best for daily personal reminders: TickTick / Due — habit tracking or persistent nagging alerts
- Best no-frills built-in option: Apple Reminders — fast, free, Siri-friendly
- Best for shared family use: Any.do — calendar, grocery lists, and shared projects in one view
- Best one-time purchase: Things 3 — no subscription, Apple-only
The list splits into two clear groups: lightweight personal reminder programs and platforms designed to keep work visible across a team. For teams already tracking clients and deals, notification tools tend to work best when they’re built into a broader CRM for small business rather than living in a separate app.
How to Choose the Right Reminder App
Start with who needs to see the reminder. If it’s just you, a free built-in app like Apple Reminders or Google Tasks is usually enough. If reminders need to reach a teammate, a client, or a recurring business process, a personal app will start to show cracks fast.
Consider platform support next — Apple-only tools won’t help a mixed-device team. Then compare free versus paid plans based on the features you’ll actually use.
If your reminders are really about tracking work rather than personal errands, look for a system where reminders stay connected to tasks, deadlines, and ownership. Small teams outgrowing sticky notes and shared docs often find that task management for small teams solves this more permanently than a standalone reminder app ever could.
Where This Leaves You
A good reminder app solves the “did I forget?” problem for one person. Teams eventually run into a different problem: digital planner programs that only live on one phone don’t help anyone else. Once reminders are about deadlines, clients, or handoffs between people, they work better when they’re connected to the task itself.
The right tool depends on that distinction. For personal errands, a simple free scheduling app may be all you need. For shared work, reminders need context, ownership, and a clear connection to the work that follows.
If you’re choosing an app for a team, platform support is only one consideration. You may also need to know whether reminders can be assigned to other people and stay connected to the underlying task — something a work-management platform such as Planfix is designed to handle.
FAQ
What features should I look for in a reminder app?
The most useful apps make it easy to capture a task, choose when you need to be reminded, and reliably deliver the notification. Depending on your needs, look for recurring planners, cross-device sync, multiple notification options, natural-language input, location-based reminders, and task sharing or assignment.
Can reminder apps help with recurring tasks?
Yes. Most modern calendar management apps support recurring tasks, but their flexibility varies. Simple apps may handle schedules such as daily, weekly, or monthly reminders, while more advanced tools support custom recurrence patterns.
Recurring reminders are particularly useful for routine work, follow-ups, maintenance tasks, bill payments, habits, and other actions that need to happen repeatedly.
Can planner apps be used for team tasks?
Yes, but not every reminder app is designed for team workflows. Shared lists can be enough for simple family tasks, shopping lists, or small group projects. For more structured work, you may want features such as task assignment, deadlines, recurring workflows, notifications, and collaboration.
Planfix is designed for this type of use case, allowing reminders to be tied to assigned work and notifying the people responsible for a task — including keeping client and deal records connected to your workflow rather than tracking them separately.
When should I use a reminder app instead of a calendar?
Use a calendar when the exact time of an event matters, such as a meeting, appointment, or scheduled call. Use a planner program when you need to remember an action, especially when the task doesn’t have a fixed time.
Is there a planner app that works across Windows, Android, and iPhone?
Yes. Todoist, TickTick, and Microsoft To Do all support the major desktop and mobile platforms, making them practical choices for people who switch between Windows, Android, iPhone, or Mac.
