## What it is
GT (Great Tit) is a portable on-device debugging tool from Tencent that acts as an Integrated Debug Environment running directly on smartphones. It supports quick performance tests (CPU, memory, traffic, power, fluency), log and crash viewing, network packet capture, and in-app parameter debugging via a console app plus an embeddable SDK.

## Use cases
- test app CPU, memory, traffic, power and fluency on a phone without a PC
- view developer and crash logs directly on the device
- capture network packets from a mobile app
- debug and modify app internal parameters at runtime
- measure code time-consumption on a real device
- build custom GT plugins for specialized debugging

## When to choose
- you need on-device performance testing of Android or iOS apps without connecting to a computer
- you want an embeddable SDK plus console app for runtime parameter tuning and log inspection
- you need quick field debugging of mobile apps on real hardware

## When to avoid
- you need desktop or server-side profiling tools
- you require a project with an explicit open-source license
- you need actively developed tooling with recent community activity
