About the project
Hot Wheels Collection Tracker is an independent Android app and a public catalogue of 1:64 Hot Wheels castings. It is not a Mattel product and it is not a price guide: it is a record of what was made, what it looks like, and what collectors are actually looking at.
What this is
The catalogue indexes more than 62,000 models from 1968 to today, with up to 22 fields per casting: series, release year, colour, tampo, window and interior colour, wheel code, base type and colour, base codes, country of manufacture, toy and assortment numbers, collector number, scale and card variant. Browsing and search need no account. An account is needed only to save a collection or a wishlist.
Two things sit on top of the catalogue: the model pages, which document each casting, and the guides, which are written from the catalogue itself rather than from general knowledge. When a guide says that 24,645 models carry a readable base code, that figure comes from querying the same data the app uses.
Who runs it
The project is built and maintained by Cristian, a collector and developer. It started as a way to keep a personal collection in order and grew into a catalogue other collectors use. The app is free; banner advertising and affiliate links to Amazon, eBay and AliExpress cover the running costs. They never unlock features.
How the data is produced
The catalogue is compiled from public collector sources and from community data, not from official Mattel material. Each casting is described with the fields above; where a field is not known, it is left empty rather than guessed, and the model page says so in words.
Figures about what collectors own, want or look up come from aggregate use of the app — for example, how many collections contain a casting. They are never derived from personal data, and no individual collection is published. Each guide states the date its data was read, so a number quoted from it can be traced back to a moment in time.
What this site is not
- Not an official Mattel or Hot Wheels service. Hot Wheels is a registered trademark of Mattel, Inc. This project is not affiliated with, endorsed by or sponsored by Mattel.
- Not a price guide. The app records what a collector paid for a car. It does not claim to know what that car is worth.
- Not a shop. Affiliate links point to marketplaces; the catalogue itself sells nothing.
