User Reviews

User reviews are mixed. Some users report accurate speeds and useful traffic-monitoring capabilities when the app is set up and calibrated correctly. However, many describe the app as unreliable and difficult to use, with frequent inaccuracies, heavy setup requirements, background-motion false readings, and persistent errors. Compatibility and support concerns are also noted. The app can be helpful in ideal conditions but is not consistently dependable for everyday use.
Pros
  • Accurate speeds when configured/calibrated properly (often within +/- 0.5 mph).
  • Useful for monitoring traffic and identifying speeders (e.g., HOA or neighborhood use).
  • Can log speed data and capture an image with speed, date, and time.
  • Calibration by measuring the distance to the subject can improve accuracy.
  • Beneficial in ideal conditions with a stable setup and proper tracking parameters.
Cons
  • Inaccurate/unreliable readings across many attempts and locations.
  • Requires extensive setup and calibration; many parameters to configure and precise distance measurements.
  • Background motion or objects (trees, shadows, wind) trigger false readings.
  • Frequent errors/freezes and no simple reset; data point errors.
  • Support/updates appear inactive or compatibility issues on some iPhone models.

Has trouble tracking specific objects especially if things are close by, don’t recommend for anything more than 60 mph

Дякую хороший додаток але ви могли ще додати таку функцію щоб із багатьох предметів можна було вибрати один предмет і коли він рухається він слідкував за цим предметом?

Difficult to use, doesn’t work on iPhone. Waste of money.
