If you came here looking for an app that shows a person's real-time location, start with a point that changes everything: serious location apps work by... sharing. The person whose location is located installs the app, agrees to share their location with you, and can turn off this sharing whenever they want. There is no legitimate app in official app stores that shows an adult's location without their knowledge—and installing a hidden program on another person's phone can constitute the crime of stalking (Law 14.132/2021), in addition to violating the LGPD (Brazilian General Data Protection Law).
What you can do, and it works well, is to combine sharing with family, monitor a minor child with a supervision app that the device itself shows is active, notify a friend of your route home, and find your own lost phone. Below are five apps that do this, how each one asks for the other person's consent, what they offer for free, and where the paid part begins.
How Real-Time Location Works
GPS is indeed a satellite technology, but not in the way movies portray it. The satellite doesn't "see" anyone: it only sends signals, and the cell phone uses these signals to calculate its own position. For that position to appear on your map, the other person's device needs to be turned on, have battery power, and have internet access—if the data drops, what you see is the last known location, with the time it was recorded.
Accuracy is also approximate. On an open street, the error is usually within a few meters. Inside shopping malls, high-rise buildings, underground parking garages, or subways, the signal degrades, and the point may appear displaced a block or stuck in the last place where there was a good signal. Treat the little dot on the map as a useful estimate, not a certainty. Below are the five most reliable apps for this type of combined tracking.
1. Life360: Círculos de Família com Localização Compartilhada
O Life360 It's one of the most used apps for families who want to keep track of each other. It works the same way for everyone: each person installs the app, joins the same circle, and chooses to share their location. Whoever joins sees who else is in the circle and knows they are also being seen—there's no hidden mode, and any member can leave or pause location sharing.
In the free plan, you see the current location of circle members and a short history of their movements. Automatic arrival and departure alerts in more places, a longer history, driving reports, and emergency features are part of the paid subscriptions, billed monthly or annually. It's a good choice for families with teenagers or elderly people, as long as the arrangement is made openly with everyone.
2. Buscar (Find My): Dispositivos e Contatos da Apple
O Search, The feature known as Find My in English is Apple's own tool for locating devices and people within its ecosystem. It has two very different functions: finding the your own Lost your iPhone, iPad, watch, or headset, and see the location of contacts who have enabled "Share My Location" with you.
In this second case, consent is explicit: the person chooses to share for an hour, until the end of the day, or indefinitely, and their device itself makes it visible that sharing is enabled. The feature works between Apple accounts and is free. If the other person stops sharing, you simply stop seeing their location—and that's how it should be.
3. Google Maps: Compartilhamento Simples e Gratuito
Known as a navigation app, the Google Maps It also has a real-time location sharing function, and it's free. In your profile picture menu, you choose "Share location," set the duration (one hour, a custom period, or until you turn it off), and send the link to whomever you want. The other person can then track your route on the map.
The reverse is also true: for you to see someone on your Maps, that person needs to initiate sharing with their Google account. While sharing is active, the sharing device displays a permanent notification on its screen, precisely so that no one forgets they are being tracked. It's the most practical option for everyday arrangements, such as letting someone know you're on your way.
4. Google Family Link: Supervisão de Filhos Menores, à Vista
For parents who need to keep an eye on a minor child, the right approach is a family supervision app, not a hidden program. Google Family Link It's free and does exactly that: the parent installs the app on their own phone, links it to their child's account, and can then see the location of the supervised device, as well as set screen time limits and approve downloads.
The essential difference from a spy app is transparency: the child's device shows that it is under supervision, with a visible warning in the system settings. It is intended for minors within a family conversation, and not for monitoring a spouse, adult relative, or employee. It's worth explaining to the child what the app does and what it doesn't do—conversation usually resolves more than tracking.
5. Glympse: Compartilhamento Temporário que Expira Sozinho
O Glympse It solves a specific problem: showing your location for a short period of time without requiring anyone to have permanent access. You send a "Glympse" with a defined time limit—fifteen minutes, an hour—and the recipient can track your location through their browser, without needing to create an account or install anything.
When the deadline expires, the link stops working on its own. It's useful for letting family know you're returning from a trip, arranging a get-together, or providing updates on a delivery. Since sharing always originates from the sender, it's not possible to use it to track another person without their participation.
What Do These Apps Really Deliver?
In addition to showing your location on a map, location apps usually offer the following features. Note that almost all of them require the consent of the person sharing the service, and several are only available in paid plans:
- Travel historyThis shows where the device has been, usually with a few free days and longer periods only with a subscription.
- Arrival and departure alertsNotification when a circle member arrives home, at school, or at work. Limited feature in the free plan of most apps.
- Emergency button: allows you to request help by sending your approximate location to your chosen contacts.
- Finding your own deviceTo set an alarm, lock, or erase the data on your lost phone, use Apple's Find My app or Google's device location service, all within your own account.
None of them work with the phone turned off, without battery, or without internet, and none deliver exact meter readings inside buildings. Be wary of any advertisement that promises otherwise.
Beware of apps that promise to locate someone without their knowledge.
There is a market for programs that promise to locate anyone by phone number, read messages, or function invisibly on someone else's device. Besides the fact that the results almost never match the advertisement, this type of unauthorized installation exposes the installer to charges of device intrusion and stalking, and it usually comes from outside official app stores, in files that contain malware and steal the data of those who downloaded it.
If the concern is for an adult—a partner, relative, or colleague—the solution isn't technical: it's about talking and agreeing on data sharing, which any of the apps above can resolve in two minutes. If the concern is for a minor child, use explicit supervision, such as Family Link. And if the goal is the security of a team, companies do this with corporate devices and a policy signed by the employee, not with an app hidden on their personal phone.
Conclusion
Tracking the location of your loved ones in real time is possible, free in most cases, and very simple to set up — as long as the other person agrees to share. Google Maps and Find My cover the basics at no cost, Glympse covers fleeting situations, Life360 is the most complete for families who want alerts and history, and Family Link is the right option for underage children.
Choose an app that everyone in the group agrees to use, agree on the rules before installing, and remember that the location on the map is always an estimate, dependent on battery and signal. This is the safe, legal, and truly effective way to use it in everyday life.
