    GT

    Debugging tool for bug hunting and performance tuning on smartphones

    GT (Great Tit) is a portable debugging tool for bug hunting and performance tuning on smartphones anytime and anywhere just as listening music with Walkman. GT can act as the Integrated Debug Environment by directly running on smartphones. With the help of GT, you can carry out the following jobs only using one smartphone: quick performance tests (CPU, memory, flow, power, fluency tests etc.), viewing developer log and crash log, capturing the network packets, debugging the APP internal parameters and code time-consuming statistics. If the functions GT provides cannot meet your requirements, you can also develop your own GT plugins with special functions to help solving more complicated debugging issues. The IOS GT is a Framework package, which must be compiled into your APPs before being used. It can be supported by both iPhone and iPad APPs.
