Location-Based Reminders on iPhone and Mac: The Complete Guide

Your phone knows where you are at all times. Location-based reminders put that knowledge to work by triggering notifications exactly when you arrive at or leave a specific place. Instead of remembering to check your to-do list at the grocery store, the grocery list finds you. Apple Reminders has offered this feature for free since iOS 5, and it remains one of the most underrated productivity tools on every iPhone and Mac.

This guide covers everything you need to set up, customize, and troubleshoot location-based reminders across your Apple devices. Whether you want to be reminded to buy milk when you pull into the parking lot, or to email your boss the moment you arrive at the office, you'll learn how to make it work reliably.

What are location-based reminders?

Location-based reminders are notifications that fire when your device detects that you've arrived at or departed from a specific geographic area. Apple Reminders uses your iPhone's GPS, Wi-Fi positioning, and Bluetooth to define a virtual perimeter — called a geofence — around any address or point of interest. When you cross that boundary, the reminder appears as a push notification.

This is different from time-based reminders, which fire at a specific clock time regardless of where you are. Location-based reminders are context-aware: they understand that "buy dog food" is only relevant when you're near the pet store, not at 3pm on a Tuesday. Apple's implementation uses significant location changes rather than continuous GPS tracking, so the battery impact is minimal.

How do you set a location-based reminder on iPhone?

Open the Reminders app on your iPhone and create a new reminder (or tap an existing one). Then follow these steps:

1. Tap the calendar/clock icon (or the "i" detail button) on the reminder.
2. Toggle on Location.
3. Choose a suggested location (Home, Work, Getting in Car, Getting out of Car) or tap Custom to search for any address or place.
4. Select Arriving or Leaving to choose when the notification fires.
5. Optionally, adjust the geofence radius by dragging the circle on the map. The minimum is about 100 meters; the maximum is roughly 150 kilometers.
6. Tap Done.

The reminder will now trigger automatically when your iPhone detects you've crossed the geofence boundary. No need to open the app — it works in the background.

How do you set a location-based reminder on Mac?

Location-based reminders on Mac work through iCloud sync. Create the reminder on your Mac in the Reminders app, click the info button (the "i" icon), check At a Location, and type an address. Choose Arriving or Leaving, then close the detail panel.

Since your Mac doesn't travel with you like your iPhone does, the actual notification will be triggered by your iPhone or Apple Watch when you physically reach the location. The Mac is simply the creation tool — think of it as a convenient way to set up reminders while working at your desk. The geofence logic runs on whichever device you carry.

This is where tools like Side Reminder add value: you can create the reminder quickly from the screen edge on your Mac without switching away from your work, and your iPhone handles the location trigger when you're on the move.

What are the best use cases for location reminders?

Location-based reminders shine in situations where the context of being somewhere matters more than the time of day. Here are the most practical use cases:

The "Leaving" trigger is particularly useful for things you need to do on the way somewhere. "Pick up dry cleaning" triggers when you leave the office, giving you time to reroute before you're already home.

How does Apple Reminders compare to other apps for location reminders?

Apple Reminders is the only major task manager that offers location-based reminders completely free with no subscription or feature gate. Here's how it stacks up:

This is a genuine competitive advantage for Apple Reminders. In our comparison of Apple Reminders, Todoist, and Things 3, location reminders was one of the standout features that made Apple's free offering compelling against paid alternatives.

Can you use location reminders with shared lists?

Yes. When you create a location-based reminder in a shared iCloud list, every participant in that list receives the location-triggered notification on their own devices. This is powerful for families and households.

For example, create a shared "Groceries" list with your partner. Add "Buy coffee beans" with a location trigger for your local grocery store. Whichever person arrives at the store first gets the notification. No need to text "can you pick up coffee" — the reminder handles it automatically.

This also works well for roommates sharing a "Household" list. "Take out trash" triggers for whoever arrives home first on trash day. The combination of location + shared lists turns Apple Reminders into a lightweight household coordination tool.

How do you set a reminder for getting in or out of your car?

Apple Reminders offers two special location types that don't use a fixed address: Getting in Car and Getting out of Car. These trigger when your iPhone connects to or disconnects from your car's Bluetooth system (CarPlay or paired Bluetooth audio).

"Getting in Car" is ideal for reminders like "Check tire pressure" or "Call the dentist" — things you want to handle during your commute. "Getting out of Car" works for "Don't forget the laptop in the back seat" or "Move car before meter expires in 2 hours."

To use these, your iPhone must be paired with your car's Bluetooth. When creating the location trigger, simply select Getting in Car or Getting out of Car from the suggested locations instead of typing an address.

Why aren't my location reminders working?

If location-based reminders aren't firing, check these common issues in order:

1. Location Services must be enabled. Go to Settings > Privacy & Security > Location Services. Make sure it's turned on globally, and that Reminders is set to While Using the App or Widgets (not "Never").
2. Precise Location must be on. Under Settings > Privacy & Security > Location Services > Reminders, toggle on Precise Location. Without this, the geofence may be too imprecise to trigger reliably.
3. Background App Refresh must be enabled. Go to Settings > General > Background App Refresh and ensure Reminders is toggled on. Without background refresh, the app can't check your location when it's not in the foreground.
4. Do Not Disturb and Focus modes. If a Focus mode is suppressing Reminders notifications, the alert won't show even if the geofence is crossed. Check Settings > Focus and ensure Reminders is allowed through.
5. The geofence radius may be too small. GPS accuracy in urban areas can vary by 10-50 meters. If your geofence is set to the minimum radius (~100m), the device might not detect the crossing reliably. Try increasing the radius.
6. iCloud sync issues. If you created the reminder on Mac but your iPhone doesn't show it, check that both devices are signed into the same Apple ID and that Reminders sync is enabled in iCloud settings.

How do you combine location reminders with time and tags?

Apple Reminders lets you stack triggers. A single reminder can have both a location and a time condition, which means "remind me when I arrive at the office, but only between 9am and 6pm." This prevents the notification from firing if you happen to drive past the office on a weekend.

Combine this with tags from a GTD system and you get powerful context filtering. Tag errands with #errands, set each one with the appropriate store location, and use a Smart List filtered by #errands to see everything you need to pick up in one view before you leave the house. When you're actually at each store, the individual location triggers fire automatically.

You can also add a flag to high-priority location reminders so they appear in the Flagged Smart List. This creates a quick-glance view of your most important location-based tasks across all lists.

Is there a limit to how many location reminders you can have?

Apple doesn't publish an official limit, but iOS enforces a system-wide cap of approximately 20 active geofences per app. In practice, this means you can have around 20 location-based reminders active simultaneously in the Reminders app. If you exceed this, older geofences may be silently deactivated.

For most people, 20 is more than enough — you rarely need location triggers for more than a handful of recurring places (home, office, grocery store, gym, school). If you're hitting the limit, consider whether some reminders could be converted to time-based triggers instead.

Completed reminders automatically release their geofence slots, so there's no housekeeping needed. Just mark tasks done and the system recycles the capacity.

Can you use location reminders on Apple Watch?

Yes. Apple Watch with GPS (Series 3 and later) supports location-based reminder notifications. When your Watch detects a geofence crossing — even if your iPhone is not nearby — the reminder fires as a haptic tap on your wrist. This is especially useful when your phone is in your bag or pocket.

You can also create location reminders via Siri on Apple Watch: raise your wrist and say "Remind me to buy batteries when I get to Target." The reminder syncs to all your devices via iCloud.

Is location-based reminders a privacy concern?

Apple processes all geofence logic on-device. Your location data is not uploaded to Apple's servers for the purpose of triggering reminders. The geofence boundaries are stored locally on your iPhone, and the matching happens in the background without any network request. According to Apple's privacy documentation, location data used by first-party apps like Reminders stays on your device and in your encrypted iCloud account.

This is a meaningful privacy advantage over third-party apps like Todoist, which would need to process your location through their own servers to deliver the same feature. With Apple Reminders, the entire workflow — from geofence to notification — stays within your personal Apple ecosystem.

What's the best way to organize location-based reminders?

Create a dedicated list called "Errands" for all location-based reminders. This keeps them separate from your time-based tasks and makes it easy to review everything you need to do when you're out. Before leaving the house, open the Errands list for a quick overview of all the places you need to visit.

For recurring location reminders (like "Check mailbox" every time you arrive home), set the reminder to repeat. Apple Reminders supports repeating location triggers, so the same reminder resurfaces every time the geofence is crossed, on the schedule you define — daily, weekly, or custom.

If you use tags and Smart Lists, you can also tag location reminders by area (#downtown, #suburb, #mall) and create Smart Lists that group errands by neighborhood. Before driving downtown, check the #downtown Smart List to batch your errands efficiently.

Is location-based reminders worth using?

Absolutely. Location-based reminders eliminate the single biggest failure mode in personal productivity: forgetting things at the moment they're actionable. You don't forget to buy milk because you're forgetful — you forget because the reminder fired at 2pm while you were in a meeting, and by the time you drove past the store at 6pm the notification was buried. A location-based reminder fixes this by notifying you when you're physically at the store, not at an arbitrary time.

The feature is free, battery-efficient, works across all Apple devices, integrates with Siri for voice input, and respects your privacy by processing everything on-device. Combined with a tool like Side Reminder that keeps your tasks visible at the screen edge while you work, you get a system where tasks are captured on your Mac and delivered to you in the real world — exactly when and where you can act on them.
