The apps listed below represent some of the best free Android apps available for working with wireless networks. Whether a home or business network user, IT student, or networking professional, these apps can help increase your productivity on Android. OpenSignal mammuth / Getty Images What We Like Accurate speed measurements. Quickly find stronger Wi-Fi. Points you to better cellular reception. What We Don't Like Signal strengths are shared publicly. Maps not updated in realtime. OpenSignal has established itself as both a leading cellular coverage map and Wi-Fi hotspot finder. Its database includes hundreds of thousands of cell towers around the world as submitted by users. Depending on your location, the app can help you find where to stand to get optimal signal strength on your phone. An integrated connection speed test feature, data usage statistics, and social networking options are also useful in some scenarios. Wifi Analyzer (farproc) Busakorn Pongparnit / Getty Images What We Like Shows signals by channel. Free to download and use. Clear indicators of Wi-Fi signal strengths. What We Don't Like Slight learning curve. Cluttered with lots of information. Many consider Wifi Analyzer the best signal analyzer app for Android. Its ability to scan and visually represent Wi-Fi signals by channel can be extremely helpful when troubleshooting wireless signal interference issues in a home or office. inTechnician (MetaGeek) Dong Wenjie / Getty Images What We Like Room by room Wi-Fi analysis. Troubleshoot wireless problems. Somewhat expensive monthly plan. What We Don't Like Only available for Windows. Poorly designed interface. Both offer similar wireless network scanning features, but some people prefer the user interface of InSSIDer over that of Wifi Analyzer. Reviewers have noted that InSSIDer may not fully support scanning of 2.4 GHz Wi-Fi channels 12 and 13 that are popular outside of the U.S. ConnectBot Atomic Imagery / Getty Images What We Like Free to download and use. Remotely control computers. Open source and free. What We Don't Like Difficult to use on a phone screen. Supports one SSH connection at a time. Network professionals and remote access aficionados are always needing a good Secure Shell (SSH) client for system administration or scripting work on servers. ConnectBot boasts many loyal followers who greatly appreciate its reliability, ease of use, and security features. Working with command shells isn’t for everyone; don’t worry if this app sounds uninteresting. AirDroid Dong Wenjie / Getty Images What We Like Affordable yearly plan. Easy to use. Quickly transfer files. What We Don't Like Limited features with free version. Commands are sometimes delayed. Mirroring can be unreliable. AirDroid supports wireless remote control of an Android device through its user interface. After installing the app and joining the device to a local Wi-Fi network, you can connect to the device from other computers through standard Web browsers. Especially useful for wireless file sharing, the app also allows you to manage Android text messages and phone calls. Bluetooth File Transfer (Medieval Software) kenex / Getty Images What We Like Does not require root. Intuitive interface. Simple drag and drop file transfers. What We Don't Like Transferring large files can be slow. Trial version expires after 10 days. Numerous Android apps allow you to share files over a Wi-Fi connection, but most are useless when no Wi-Fi is available. That’s why it’s essential to keep an app like Bluetooth File Transfer handy that supports file sync over Bluetooth connections with other mobile devices. This app is especially easy to use and includes some nice features like displaying thumbnail pictures for photos and movies, optional document encryption, and the ability to configure which devices are allowed to share with you. Network Signal Speed Booster 2 (mcstealth apps) John Lund / Getty Images What We Like Find low signals in dead zones. Free to download and use. What We Don't Like Unreliable signal improvement. Signal improvement is usually small. Difficult to determine if app is working. This app (formerly called “Fresh Network Booster”) has been billed as the "number one" cell signal booster for Android. This version 2 updates the original with additional device support. It automatically scans, resets and reconfigures your phone’s cellular connection attempting to increase its signal strength. Designed to be used when the carrier’s signal is lost or weak, some reviewers claim the app improved some of their connections from zero or one bar to at least three bars. The app won’t always be able to improve your connection in all cases, though. It uses a set of built-in network speed tweak techniques that run automatically when the app is launched, with no user configuration involved. JuiceDefender (Latedroid) Buree Lalitathada / Getty Images What We Like Free to download and use. Easy to use. Prolongs battery life. What We Don't Like Can adjust the same settings and save battery without the app. May not work on all phones. The wireless network interfaces of a phone or tablet drain its battery life quickly. JuiceDefender is designed to add minutes or even hours the battery charge by implementing automatic power-saving techniques for an Android device’s network, display, and CPU. This extremely popular app features five free built-in power-saving modes to choose from, plus other options controlling the conditions for automatically turning Wi-Fi radios off and on. Note that some of JuiceDefender’s most powerful features like the ability to switch from 4G to lower-power 2G/3G connections are not offered in the free app but only available in the paid Ultimate version.
