About FastTrack — Who Builds It & How We Test
FastTrack is built and maintained by Anthony Horner, founder of Fasttrack LLC. The same person who writes the app's GPS timing engine writes the guides and data articles on this site — first-hand engineering, not aggregated content.
How FastTrack is tested
The app fuses GPS Doppler velocity with the phone's accelerometer at 100Hz and is validated against dedicated GPS performance hardware. The full methodology is documented on the accuracy page.
Editorial standards
- Ranked tables label every figure as manufacturer-claimed or independently tested — the two are never mixed silently.
- Numbers presented as FastTrack-measured come only from real GPS-verified runs recorded in the app.
- Ranked-list posts show an "Updated" stamp only when the underlying data actually changed.
- Flagship data tables are downloadable as CSV, free to reuse with credit.

Frequently Asked Questions
Who writes the articles on fasttrackapp.biz?
Every guide and data article is written and reviewed by Anthony Horner, the founder of Fasttrack LLC and the developer of the FastTrack app. There is no content farm behind the site — the same person who builds the GPS timing engine maintains the published data.
Where do the 0-60 and quarter-mile numbers come from?
Ranked tables compile manufacturer-claimed figures and independent instrumented tests, and every row is labeled with its source basis. Numbers described as FastTrack-measured come exclusively from real GPS-verified runs recorded in the app — the two are never mixed.
How is FastTrack itself tested?
The app fuses GPS Doppler velocity with the phone's accelerometer, and its accuracy is validated against dedicated GPS performance hardware. The methodology is documented in detail on the accuracy page.
