The short answer
For phone and location reminders, use your phone's built-in app: Apple Reminders on iPhone, Google Tasks on Android. For reminders on every device with more control, Todoist or TickTick. For work reminders that come from client calls and email, on Mac and Windows, SayBriefly attaches the reminder to the task, the project card or the calendar event it belongs to.
What a reminder app actually does
A reminder app has one job: tell you about something at the moment you can act on it. Everything else, the lists, the tags, the colors, is there to support that one moment. If the alert comes at the wrong time, in the wrong place, or without enough context to act, the app has failed no matter how pretty it is.
That gives you a simple test for any reminder application. When the alert fires, can you act in the next minute? A reminder that says "Harbor" at 7am on your phone while you are making coffee fails the test. A reminder that says "Send Harbor the revised scope, their email is linked" at 10am on the computer you work on passes it.
So the question is not which app has the most features. It is which app puts the reminder where you will be, with what you need to act.
The four kinds of reminders
Time
At 10:00 on Friday. Every app does this. It is the backbone.
Place
When I get home. Phones do this well, computers do not.
Repeat
Every month on the 1st. Rent, invoices, plants.
The fourth kind is the one most apps skip: the context reminder. It fires about a thing, and the thing comes with it. A reminder on a to-do opens the to-do. A reminder on a meeting opens the meeting. A reminder on a client's project card opens the card with its history. This is the kind that matters most at work, because work reminders are rarely "do X". They are "do X for this client, as promised on Tuesday's call".
Phone reminders or computer reminders?
This is the most important choice, and most roundups skip it. Where the reminder lands decides whether it works.
| On your phone | On your computer | |
|---|---|---|
| Best for | Life: errands, pills, calls to family, bins | Work: follow-ups, invoices, replies, prep |
| Location reminders | Yes, in most built-in apps | Rarely useful |
| Context to act | Small screen, you usually act later | The email, the file and the task are right there |
| Risk | Swiped away and forgotten | Missed if you are away from the desk |
The honest answer for most people is both, split by purpose. Keep life reminders on the phone app you already have. Keep work reminders where the work happens, which for most freelancers and studio leads is a Mac or a Windows PC. Trying to force one app to do both is where people end up with 60 overdue reminders and no trust in any of them.
Reminders for work vs reminders for life
Life reminders are simple. "Buy milk" needs no background. "Call mum Sunday" needs no link. A phone app with a widget is perfect for them.
Work reminders are different in three ways:
- They are born somewhere. On a call ("I'll send it Thursday"), in an email ("can you get back to us by the 3rd?"), in a project. If you have to retype them into a separate app, some never make it.
- They need context. "Chase Northwind" is useless without knowing what was promised and when.
- They belong to someone. A client, a project, a colleague. Grouping them by client is what lets you answer "what do I owe Harbor?" in ten seconds.
This is why a general reminder app, however good, leaves gaps at work. It is also why SayBriefly puts reminders on the things work is made of: to-dos, project cards and calendar events. More on that below, and on the to-do list app page.

The reminder apps, one by one
Apple Reminders: the best built-in
If you have an iPhone, you already own one of the best reminder apps. Apple's support pages list time and location alerts, early reminders for an extra nudge before the main one, a reminder when you are messaging a particular person, tags, subtasks and grocery lists that sort items into sections. Siri adds reminders by voice, and it syncs to your Mac through iCloud. Where it stops: no Windows or Android app, and nothing arrives in it on its own from your calls or inbox. Full detail on the Apple Reminders alternatives page.
Google Tasks: where Google's reminders live now
Google moved its old Calendar and Assistant reminders into Google Tasks. Google's help pages say the switch is permanent. Add a task with a date and time and you get a notification then; tasks with only a date notify at 9am. Tasks can repeat. Google Assistant still sets time reminders by voice, which land in Tasks, but Google says location reminders are no longer available there. Step by step on the Google Calendar reminders page.
Microsoft To Do: the pick for Outlook people
Microsoft's support pages show a "Remind me" option (later today, tomorrow, next week or a date and time you pick), due dates, and repeats from daily to custom. You can type "call Sam tomorrow at 3pm" and it recognizes the date and time. It ties into Outlook, which makes it the natural home if your week runs in Microsoft 365.
Todoist: reminders everywhere, with a plan split
Todoist runs on web, Mac, Windows, iPhone, iPad and Android. Its help center says tasks with a date and time get an automatic reminder on all plans, while extra custom reminders and recurring reminders need a paid plan. Its strength is typing dates in plain language and having them work on every device.
TickTick: reminders that nag until done
TickTick's features page lists a "constant reminder" that keeps alerting until the task is done, email reminders, repeating reminders, location alerts on iOS, and a daily review reminder. It also packs a calendar, a habit tracker and a pomodoro timer, so it suits people who want one app for personal planning.
Any.do: reminders in WhatsApp
Any.do advertises time, location and recurring reminders, and a WhatsApp link that lets you create tasks and get reminders inside WhatsApp. It runs on phones, Mac, Windows, web and watches. If WhatsApp is where you live, that is a real reason to pick it.
SayBriefly: work reminders from calls and email
SayBriefly is not a phone reminder app and does not try to be. It is a Mac, Windows and web app where your calls, email, to-do list, calendar and client projects share one memory. A reminder attaches to a to-do, a project card or a calendar event, and fires as a notification in the app. Tasks can come straight from your calls and email, and when an email gave a deadline, the task can carry a reminder already. No location reminders, no repeats and no phone app.
A worked example: a freelancer's reminders from one call and one email
Maya is a freelance brand designer with four clients. Here is one Tuesday, and where each reminder came from.
- 10:00, Harbor weekly call. Near the end she says: "I'll send the revised scope by Thursday." After the call, a task appears on her list: "Send Harbor the revised scope", linked to the call note.
- 10:40, she adds the nudge. On the task she clicks Remind me, picks Thursday at 9:00. Now it is in the Reminders tab under Later.
- 11:15, an email from Northwind. Their ops lead writes: "Could you send the invoice for September by Friday the 2nd?" A task arrives from the email, "Send Northwind the September invoice", carrying a reminder because the email gave a deadline.
- 13:00, she asks Scribbble. In chat she types: remind me Friday at 10 about the Harbor invoice. The agent sets it on the matching task.
- 16:00, life stuff goes to the phone. "Pick up dry cleaning when I leave the studio" goes into Apple Reminders with a location. That is what the phone is for.
- Thursday 9:00. A notification appears in SayBriefly, a couple of minutes after nine. She clicks it, the task opens with the call note, she sends the scope and ticks it. It moves to Completed in the Reminders tab.
Nothing here needed her to retype a promise into a second app. The work reminders stayed with the work, and the life reminder stayed on the phone.
Example of the layout with made-up names.
How to set a reminder that actually works
- Remind the moment you can act, not the deadline. If the invoice is due Friday, remind Thursday morning. A reminder at the deadline is a reminder that you are late.
- Start with a verb. "Send", "call", "reply", "book". A noun ("Harbor") makes you think again at alert time.
- Put it on the thing, not next to it. A reminder on the task opens the task. A free-floating reminder opens nothing.
- Pick the right device. Errands on the phone. Desk work on the computer you work on.
- One reminder per promise. Three nudges for the same task teach you to ignore all three.
- Review once a day. Open the overdue list every morning. Do, move or delete. Never let it grow past a screen.
A reminder is a promise to your future self. Make it easy to keep.
Reminder wording you can copy
Good reminders read like a note from a helpful colleague. Paste and adapt these.
Send Harbor the revised scope (promised on Tue call) Chase Northwind for the signed quote if no reply by now Reply to Sam: yes to logo files, ask for SVG Prep 3 questions for the Harbor review at 14:00 Invoice Northwind for September (due Fri 2nd) Check the Harbor staging link before the client sees it
Take the bins out (every Tuesday, 20:00) Pick up the parcel (when I arrive at the post office) Call mum (Sunday 11:00) Renew car insurance (1 week before the 14th)
Common reminder mistakes and how to fix them
- Reminding at the deadline. Fix: remind the day before, or the morning of, with time to act.
- Everything gets a reminder. Soon you swipe them all away. Fix: reminders only for things with a real time or a real promise.
- Work reminders on a phone at night. You see it, you cannot act, you forget. Fix: put work reminders on the computer.
- Snoozing forever. A task snoozed three times is a decision you are avoiding. Fix: reschedule it with a real time, or delete it.
- Two apps for the same thing. A reminder in one app and the task in another drift apart. Fix: keep the reminder on the task.
- Promises that never become reminders. "I'll send it Thursday" said on a call and never written down. Fix: an app that catches tasks from calls, or a two-minute habit of writing them down right after.
How reminders work in SayBriefly
On the thing
Attach a reminder to a to-do, a project card or a calendar event.
Ask Scribbble
Type it in chat: remind me Friday at 10 about the Harbor invoice.
From email
Tasks from email carry a reminder when the email gave a deadline.
- Remind me. On a task, pick in 30 minutes, in 1 hour, in 3 hours, tomorrow, or a date and time.
- A notification in the app. At the time, SayBriefly shows a notification. Reminders are checked every 5 minutes, so one can arrive a few minutes late.
- A Reminders tab. The to-do list groups every reminder into Overdue, Today, Later, Sent earlier and Completed, so you can see what is coming and what already went off.
- Where it runs. Mac and Windows desktop apps, plus the web app.
What it does not do, plainly: no phone app, no phone push, no location reminders, no repeating reminders. For those, keep your phone's app. See also the calendar to-do list and the calendar app.
Which reminder app should you pick?
- iPhone, mostly personal: Apple Reminders. You already have it.
- Android or Google account: Google Tasks, set from Calendar, Gmail or Assistant.
- Outlook at work: Microsoft To Do.
- Every device, lots of lists: Todoist or TickTick.
- Lives in WhatsApp: Any.do.
- Client work, tasks born on calls and in email: SayBriefly for work, plus your phone's app for life.
Most people need two: the phone app for life, and a work app where the reminder sits on the task, the call or the client.
Questions people ask about reminder apps
What is the best reminder app?
For personal reminders on a phone, the one already on it: Apple Reminders on iPhone, Google Tasks on Android. For reminders across devices with more control, Todoist or TickTick. For work reminders tied to client calls and email on a computer, SayBriefly.
What are the top reminder apps in 2026?
The ones most people compare are Apple Reminders, Google Tasks (which now holds Google Calendar and Assistant reminders), Microsoft To Do, Todoist, TickTick and Any.do. Each is covered on this page, checked September 2026.
What is a reminder application?
An app that alerts you at a time you choose (or at a place, in some apps) so you do something you would otherwise forget. Most reminder apps are also simple to-do lists.
Do reminder widgets exist?
Yes. Apple Reminders, Google Tasks, Microsoft To Do, Todoist, TickTick and Any.do all offer home screen widgets on phones. SayBriefly has no phone app, so it has no phone widget. On a computer its reminders live in the to-do list's Reminders tab.
Is there a reminder app for a computer?
Yes. Apple Reminders runs on Mac, Microsoft To Do runs on Windows and Mac, and Todoist, TickTick and Any.do have Mac, Windows and web apps. SayBriefly runs on Mac and Windows plus a web app.
Which reminder app works on both iPhone and Android?
Todoist, TickTick, Any.do, Microsoft To Do and Google Tasks all have apps for both. Apple Reminders is Apple devices only.
Can a reminder app remind me at a place?
Apple Reminders can, with Location Services on. Any.do lists location reminders, and TickTick offers them on iOS. Google Assistant no longer sets location reminders. SayBriefly does not do location reminders.
Can I set recurring reminders?
Apple Reminders, Google Tasks, Microsoft To Do, TickTick and Any.do support repeats. Todoist supports them on paid plans. SayBriefly does not do recurring reminders today.
Does SayBriefly send reminders to my phone?
No. SayBriefly sends the reminder as a notification in the app on Mac, Windows or the web. There is no phone app and no phone push. For phone reminders, use your phone's built-in app.
How exact are SayBriefly reminders?
SayBriefly checks for due reminders every 5 minutes, so a reminder can arrive a few minutes after the time you set. It is built for work follow-ups, not for alarms.
Can I set a reminder by talking to an assistant?
Yes. Siri sets Apple Reminders and Google Assistant sets reminders that land in Google Tasks. In SayBriefly you can type to the agent Scribbble, for example: remind me Friday at 10 about the Harbor invoice.
What is the difference between a reminder and a to-do?
A to-do is something you have to do. A reminder is the nudge that tells you when. Good apps attach the reminder to the to-do, so the alert opens the task with its notes.
Can a reminder app help with work follow-ups?
Only if the follow-up gets into it. Most apps wait for you to type it. SayBriefly can create the task from a call or an email, and add a reminder when the email gave a deadline.
Should I use my calendar as a reminder app?
For things with a fixed time, like a call, yes. For tasks you can do any time before a deadline, a reminder on a task works better, because a calendar block that slips is easy to lose.
