#2. Network Master
This signal booster application has been tried by more than 10,000,000 people in various countries, and most of them give 4 stars with positive reviews.
Network Master was created by a company called Lionmobi Holding Limited, based in Hong Kong.
However, the official version of this application has been modified by an unknown third party and this modified version features that are already unlocked.
So, you can use this premium application for free. The drawback is that this application is not on the Google Play Store, but don’t worry. Many safe websites provide download links.
This application, in the form of a MOD APK, is feature-rich and has a user-friendly user interface, so for those of you who are new to using this kind of application, it will not take long to operate the features in it. Some of the main functions of this application are:
- It can help strengthen the internet connection on a smartphone while making it easier to test the internet connection’s speed.
- A WiFi Expert feature will help optimize the internet connection that is being used by detecting any application running in the smartphone background and immediately stopping it.
- It will automatically display a list of the number of connected devices and each device’s name.
The last function is guaranteed to be very useful because you will immediately know if there is an intruder device that joins your connection. You can directly change the WiFi password so the intruder can no longer use the free WiFi.
#3. WiFi Analyzer
If previous signal booster apps were beneficial for home use, WiFi Analyzer is more necessary when you’re out and about.
As the name implies, this application was created specifically to help you find signals that are around the point you are.
So if you are an individual who often does activities outside the home, WiFi Analyzer is one of the suitable applications to install.
This application will detect WiFi networks that are not given a password and whose signal is the strongest and closest to you.
Unlike the previous application, this one application you can find on Google Play is even available for free, but specifically for Android version 6 or later.
When compared to previous applications, WiFi Analyzer does not have many features.
However, the simple interface this app offers will make users feel comfortable, and although it is free, it is ad-free.
#4. WiFi Master Key
This signal booster application received good feedback from users, with a rating of 4.4. One of the advantages is that it provides 19 UI language choices, including Indian, which is the language choice that is rarely found in several global-scale applications on the Play Store.
Apparently, this language choice is available because the WiFi Master Key was made and published by a neighboring company, Singapore, with the company name Linksure Network Holding PTE. Limited. Another advantage of this application is that it is 100% free and encrypted.
This means that this application maintains users’ privacy so that all personal things on your smartphone (such as WiFi passwords) will not be stored on the application server. In other words, this application is very safe to use.
Unfortunately, you can only use WiFi Master Key as a booster application. You can’t find a WiFi signal without a password in public areas like the WiFi Analyzer app earlier.

As the name implies, this application will refresh your WiFi network regularly (usually every 20 – 30 seconds) so that your signal is always in the best condition and ultimately makes activities with the internet smoother.
