Console logs are a collection of diagnostic messages that your application records on your device or server. This helps the developers to figure out whats going on with your application and find ways to solve. When it comes to iOS devices, prior to iOS8 one should be able to use iPhone Configuration Utility to view the device logs but not anymore unless you have XCode. LemonJar’s iOS eConsole is an awesome free app which solves the problem by giving easy access to console logs even without having to install XCode in your mac.
All one need to do is, just download the app, connect your device to your MAC via USB and and launch iOS Console app and start capturing your logs. I personally prefer LemonJar’s iOS Console to the XCode console log because of its powerful filtering ability which I can use it to filter the logs and export it later for further analysis.
