Frequently Asked Questions

We use a proprietary **AI/Machine Learning model** that analyzes millions of data points, including real-time marketplace sales, historical depreciation trends, condition, carrier lock status, and manufacturer trade-in rates. Our goal is to provide a precise value range, not just a single static number. (See our Methodology page for more detail).

The value of a used phone depends heavily on where you sell it. The **low end** usually represents a guaranteed instant cash offer from a buyback company. The **high end** represents the price you might achieve through a private sale (like eBay or Facebook Marketplace), which maximizes profit but requires more effort.

Our data feeds are updated **in real-time**, typically every few minutes, to reflect the dynamic nature of the used smartphone market. Factors like a new iPhone announcement can cause instant depreciation, and our algorithm captures these shifts immediately.

No, the price is an **expert estimate** only. The final offer you receive is determined by the actual third-party buyer (reseller or carrier) after they physically inspect your device. Discrepancies often arise from undisclosed damage or faulty components (like poor battery health).

Our goal is to give you the most comprehensive market overview. If you find a better legitimate price, congratulations! We encourage users to use our tool as a benchmark to ensure they are getting the best possible deal when selling.
