Guide: Questions you should ask yourself before buying a Bluetooth Tracker

What is a Bluetooth Tracker?

A Bluetooth Tracker is a small technical device, usually in the form of a pendant, with which you can locate objects and thus, for example, find lost objects via Bluetooth connection. There is usually an app that goes with the device, which you can download to your smartphone.

Bluetooth trackers come in many different shapes, sizes and designs, so there is a Bluetooth tracker for every application.

What is a Bluetooth Tracker used for?

A Bluetooth Tracker is a versatile tool and can help you in many different situations. Most of the time, the tracker is used to find valuables if they are lost. This way you can quickly avoid hours of searching for your front door key.

You can put the Bluetooth tracker in your wallet or attach it to your key ring, so they are also well protected against theft.

Many people also use Bluetooth trackers to monitor their car or pet. The latter is especially popular with dog and cat owners, as you can quickly find your pet again if it should run away. With the help of Bluetooth trackers, you can also track the movements of your child or vulnerable persons. However, pay attention to the applicable data protection guidelines.

How does Bluetooth tracking work and how do I establish a Bluetooth connection?

Bluetooth tracking usually works by installing an app on your smartphone or software on your computer that is compatible with the Bluetooth tracker.

The necessary tracking programme is provided by the manufacturer of the Bluetooth tracker and is usually compatible with Android and iOS devices. With some apps, you have to pay monthly fees for tracking, so you should read the product description carefully before you buy. Then connect the tracking device to your Bluetooth-enabled mobile phone.

You can usually do this in the system settings of your mobile phone. The GPS of your smartphone is now used for tracking and shows you on the map of the app exactly where the Bluetooth tracker and thus also the valuable item is located. In the meantime, there are different Bluetooth versions, which is why you must make sure that your mobile phone is up to date.

What alternatives are there for Bluetooth trackers?

You can also buy a GPS key finder as an alternative to a Bluetooth tracker. This is usually more expensive, but is characterised by its unlimited range, as the device itself uses GPS for tracking and therefore does not require a mobile phone connection.

There are also key finders with sound activation, which are mainly suitable for domestic use. For example, if you clap your hands, the sensor activates an alarm signal that guides you to your valuables. A classic alternative to a Bluetooth tracker is a wireless key finder, which is no longer sold as often these days.

Type Explanation

GPS key finder with online location localisation via app or website, location signal of the tracker via map display on website or app
Key finder with noise activation localisation via noise sensor, location signal of the tracker as alarm signal when activated by a specific noise

Decision: What types of Bluetooth trackers are there and which one is right for you?

If you want to get a Bluetooth tracker, there are two alternatives you can choose between.

  • Bluetooth Tracker with Smartphone Search
  • Bluetooth Tracker with Crowd Search

With Bluetooth trackers, you have a choice of search functions. Some models can connect to other phones and search for multiple people, while others can only search for one smartphone. The following section will help you make your decision.

What are the features of a Bluetooth tracker with smartphone search and what are its advantages and disadvantages?

With the help of a Bluetooth tracker with smartphone search, you can not only locate your valuables from your mobile phone, but you can also determine the location of your smartphone if you have misplaced it. All you have to do is connect your smartphone to the Bluetooth Tracker.

  • Two locating functions in one Bluetooth tracker
  • Quick location of your mobile phone via ringtone and/or camera flash
  • Bluetooth connection must be maintained at all times
  • Limited range of approx. 80m

If you want to locate your mobile phone, all you have to do is press the button on the tracker and it sends the information to your mobile phone, which then emits a ring tone. Even if your mobile phone is muted, it will make itself heard and you can locate it easily. If you choose a Bluetooth tracker with smartphone search, the following advantages and disadvantages may arise.

What are the advantages and disadvantages of a Bluetooth Tracker with Crowd Search?

With a Bluetooth Tracker with Crowd Search, it can use a crowd of people to locate your valuable item. This works by subconsciously connecting your Bluetooth tracker to other smartphones that use a tracking function. They then send up-to-date location information to the server, which in turn tells you the location you are looking for.

  • Very accurate location through multiple connection points
  • Very fast location through multiple connection points
  • Relatively high range through the connection of multiple devices
  • Limited range up to approx. 80m
  • You always need a crowd
  • Questionable nature of possible access to location data (of valuables and the tracker) by third parties

With crowd search, the location can be determined even faster and more clearly. If you decide to use a Bluetooth tracker with crowd search, the following advantages and disadvantages may arise.

Purchase criteria: You can use these factors to compare and evaluate Bluetooth trackers

The following section will help you find the right Bluetooth tracker for you. The criteria you can use to compare Bluetooth trackers include:

  • Bluetooth version
  • Location signal
  • Range
  • Water & dust protection
  • Power supply, battery & battery life
  • Dimensions, weight & design

In the following paragraphs, we explain what each criterion is about.

Bluetooth version

Bluetooth is a radio standard for the wireless transmission of all kinds of data. Since the development of Bluetooth in 1990, there have been constant updates and newer, improved versions.

The most common Bluetooth trackers connect with version 4.0 and more recent versions.

The exact devices for which the tracker is suitable are usually specified by the manufacturer. The latest Bluetooth version available since June 2016 is the 5.0 version.

Location signal

The location signal can be different for Bluetooth trackers depending on the model. Generally, when you locate your valuables, the location is displayed on a map in the app. This app accesses the GPS via your smartphone.

In addition, most trackers sound an alarm signal as soon as tracking begins. This is usually an alarm tone of up to 80D. However, some models also have an LED display that flashes or lights up continuously when tracking is in progress.

Every Bluetooth tracker comes with a matching tracking app that you can use to find the location of your valuables. With some models, it is even possible to track the location in real time. (Image source: / Ingo Joseph)

Bluetooth trackers with smartphone search will sound your pre-set signal tone on your mobile phone, even if you have switched your mobile phone to mute.


The range of Bluetooth trackers is limited. As a rule, the Bluetooth connection reaches 80-100m, depending on the track. However, there are also models that have a much shorter range.

This means that as soon as your smartphone moves too far away from your Bluetooth tracker, the Bluetooth connection is disconnected and you cannot determine the location of your valuables.

In the case of Bluetooth trackers with crowd search, if the range is insufficient, the tracker simply connects to another smartphone that has the tracking app installed. This allows the location to be quickly pinpointed across multiple people at a range of over 100m.

Water & dust protection

Some outdoor Bluetooth trackers are water- and/or dust-proof. These are particularly suitable for hiking, cycling or tracking your pet. How robust and waterproof your Bluetooth tracker ultimately is depends on the IP rating. This IPX index is a guideline for how much water an electronic device can easily withstand and is usually stated by the manufacturer in the product description or packaging.

Explanation Index
No protection IPx0
Drip-proof IPx1
Protection against dripping water when the device housing is inclined by 15% IPx2
Protection against water spray with an angle of incidence up to 60% IPx3
Protection against water spray from all directions IPx4
Protection against water jets from all directions IPx5
Protection against powerful water jets from all directions (temporary flooding) IPx6
Protection against temporary submersion IPx7
Protection against permanent submersion IPx8

Power supply, battery & battery life

Bluetooth trackers are either battery-powered or have an integrated rechargeable battery. Battery-powered trackers are usually cheaper models, as the lithium-ion battery is usually not included in the purchase.

Due to the flat shape of the trackers, they are usually button batteries, for example CR2032 batteries. The battery life varies depending on the model, but should last at least up to 8 months.

The Bluetooth trackers with integrated rechargeable batteries are usually somewhat larger, have more weight and are somewhat more expensive. One battery charge usually lasts at least 2 and a maximum of 8 months, but this varies greatly from manufacturer to manufacturer. You can charge the battery with a micro USB cable, which is usually included in the delivery.

Dimensions, weight & design

Bluetooth trackers are usually small and flat objects that are also very light. The most common dimensions of a tracker are 4cm x 4cm x 1cm. However, some models are larger, while others are more compact and therefore ideal for your wallet or keychain.

In addition, these trackers weigh about 15 - 65 grams, so they are very light and well suited for mobile transport. Bluetooth trackers come in many different shapes, colours and patterns. The most common variants are plain black, grey or white.

But you can also buy colourful Bluetooth trackers with cheerful patterns and colourful designs, which are well suited for children. The design has no influence on the functionality of the Bluetooth tracker, which is why you can choose a model that suits your personal taste.

Facts worth knowing about Bluetooth trackers

What technical interference can affect the tracking of my Bluetooth Tracker?

A Bluetooth Tracker may not work properly if the Bluetooth connection between your smartphone and the tracker is interrupted in any way. For example, if Bluetooth is switched off, the Bluetooth version is not compatible with the tracker or other apps block access.

In addition, as the distance increases, tracking may take longer and may eventually be interrupted. In addition, the Bluetooth connection usually breaks down in underground buildings, for example in underground garages. Dense forests or rooms with many technical devices can also trigger interference signals so that the Bluetooth positioning no longer works.

What legal guidelines do I have to observe when using a Bluetooth Tracker?

You can safely have your private valuables, such as your keys or wallet, tracked using a Bluetooth Tracker. However, if you want to track the location of other vulnerable people, you need their permission. Even if it is your children, they must be informed in advance that they are being monitored.

Otherwise, secretly tracking people is a criminal offence and can be prosecuted.

Since a pet is legally considered an object, you can easily track your dog or cat and determine its location.
