(For an explanation of the GPS permission, seebelow.)Displays network information and diagnostics: Ping a server (viaICMP over IPv4 or IPv6 and TCP), DNS lookup (with geographicallookup of IP addresses), reverse DNS lookup, WHOIS queries,inspecting HTTP response headers, trace routes (also with IPaddress geo lookup), check whether a range of ports is open, scan ahost for SSL versions and ciphers, and look up the location ofhosts and whether it's reachable from the public internet. It alsoshows details of the current network setup and connection of thedevice, including netstat information. "Wake on LAN" functionalityfor waking up machines. Optional "NetSentry" monitors networkinterfaces and warns of breaching usage limits.Includes a home screen widget for long-running pings.Recently used hosts, IP addresses and DNS servers are rememberedfor auto-completion.The results can be copied (via long-click on the output text), sentvia email or stored in a file as text or PDF. A history of theresults of recent operations is kept (swipe left and right toswitch between tabs).Numerous options (like using an alternative name server, Ping TTL,showing ping times for each traceroute step, Broadcast Ping, usingHTTPS, setting the HTTP port number, selection of DNS record typesto query, etc.) are available through a long-click on the "Go"button.Contains no ads.Please join the Google community "Ping & DNS" where I supportthis app, especially if you're having problems.WHY THE GPS PERMISSION? First off, GPS is only accessed if the"Show Location" checkbox is set in the Ping Options dialog. Thischeckbox is turned off by default, so unless you explicitly set it,you don't need to worry about your location ever being tracked.Tracking location is useful for measuring ping times duringlong-running pings across large areas, like a factory or auniversity campus. Once a long-running ping with location is done,a Google Earth file (.dmz) is created that shows the ping timesalong with the geo location of each ping. Most people will neverneed this option, so you don't have to worry. And even if you douse it, location data is stored on the device, it is not sent oruploaded anywhere (the exception being if you attach the GoogleEarth file to an outgoing email - in which case you're in charge ofwhere the email is sent to). So all the negative comments you maysee in the Play Store are unfounded.

SignalCheck allows users to check the truesignal strength of their connections. Unlike the standard Androidsignal bars, which typically only display the 1xRTT (voice andlow-speed data) signal strength, SignalCheck will show you detailedsignal information about all of your device's connections,including 1X, GSM, EV-DO or eHRPD (3G), LTE (4G), and Wi-Fi.Special thanks to S4GRU for their tremendous support of SignalCheckfrom the beginning! Visit http://www.S4GRU.com for up-to-the-minuteinformation and discussions about Sprint's Network Vision strategy,as well as talk about devices and other cellular networks. There isa SignalCheck discussion thread too!SignalCheck will display LTE Cell ID information on most devicesrunning Android 4.2 or higher, and some HTC devices on earlierAndroid versions. SignalCheck was one of the first (if not THEfirst) Android apps to provide this information to users. LTE bandinformation is available for some providers, and frequencies aredisplayed on some HTC devices.A configurable SignalCheck widget can be added to your home screen,showing your realtime connection type and signal strengths.SignalCheck also displays the current connection type along withthe carrier name for each connection, even while roaming. Sprintusers are instantly able to see if they are on the new 800 or 2500MHz (Spark) networks, part of Network Vision!One of the best features of SignalCheck are the notificationicon(s). A user-customizable icon shows your data connectionstrength in the notification area at the top of the screen, andmore details can be seen in the pulldown menu. Your signal strengthis always at the top of the screen along with your other icons.. noneed to open the app to check your connections. The icons arecustomizable, showing signal bars, connection type, digital signalstrength in dBm, or connection type with signal strength. Asecondary icon can be enabled to always display the 1xRTT signalfor users who wish to compare their signal strengths realtime. Allof this is customizable from within the app! Users can configurethis to automatically start when their device boots up if theychoose to.SignalCheck can also notify the user with optional audio and/orvibrating alerts when a 4G LTE connection is discovered. This ishandy for users traveling in new cities, or if your carrier'snetwork is being upgraded -- know immediately when you have ahigh-speed connection! Sprint users can also enable alerts tonotify them when they connect to 800 SMR.Curious as to which tower you are connected to? SignalCheck willnot only show you the ID, but also the street address of the 1Xtower or sector on most CDMA networks! Clicking on the address willautomatically show the location through your mapping app. Users canalso add custom "Site Notes" for each site they connect to.SignalCheck has an option to quickly reset your data connectionsfrom within the app (root required on Android 4.2+). Another optionallows users to start checking their signals as soon as theirdevice boots, enabling the notification icon(s) immediately.SignalCheck provides easy access to advanced Android screens suchas Data, Debug, Engineering, EPST, and Field Trial, along withBattery Info, Field Trial, Mobile Networks, and Wi-Fi info. Thesescreens are already available on most Android devices, but are onlyaccessible by special dialer codes.SignalCheck is a great complement to the Sensorly app, allowing youto check your signal strengths and map them out so other users cansee the data as well.This app has also been referred to as Signal Check, Signal CheckLTE, LTE Signal Check, and LTE Checker, among other things. Userschecking their signals on the Sprint network will see the mostbenefit from this app as their Network Vision nationwide upgraderolls out, but Boost, Verizon, AT&T, T-Mobile, andinternational users can also check their signals and see detailedinformation about their connections.
