We Test. We Open. We Tell the Truth.
Track & React is built by real people who have spent years installing, testing, and sometimes breaking GPS trackers — so you don't have to.
Meet Crystal Yifei Liu
Crystal Yifei Liu spent twenty years at the top of the tech world before she started Track & React. She was employee #37 at Google, where she helped build the AdWords quality scoring system. She spent seven years at Amazon as the global architect of the Associates affiliate platform. She co-founded a SaaS affiliate technology company and served as its CTO.
After leaving the corporate world, Crystal became a digital mentor and angel investor. She has guided dozens of content creators and entrepreneurs through the process of building honest, sustainable online businesses.
At Track & React, Crystal serves as the editor-in-chief. She sets the standards, reviews every article, and makes sure our recommendations are always based on evidence — never on hype or hidden partnerships.
"There are two kinds of people online: those who build, and those who find excuses. I have a feeling you're the builder."
