User Reviews

Pros
  • Accurate motion detection for racing, especially for high-speed passes
  • Easy setup and customization for basic features
  • Voice feedback is a valuable addition
  • Works well for slot cars and R/C racing
  • Fun and engaging to use with sound effects and start lights
Cons
  • Color detection mode is inconsistent and often fails, especially in challenging color combinations
  • Motion detection is limited to one racer, making it less useful for multiple cars
  • Issues with camera access where it sometimes shuts off unexpectedly
  • User interface could use improvement for better usability
  • App may freeze or not register lap counts on occasion

Tried with Scalextric. Motion trax mode works well and consistently detects cars. Colour trax mode is too inconsistent. I find it misses cars at high speed and is basically unusable

Can only add one racer for motion. Very seldom does color Trax even work. If you only need lap time for one racer, then this is the app for you. This was used for HO slot car track.
