HOWFAST by NIEWYEZT

Measure acceleration, drag runs, lap times, speed, distance and traffic.

Your car feels fast. Your friend says it is fast. The stopwatch may have a slightly less emotional opinion.

HOWFAST turns your Android device into a practical speed and driving performance measurement tool.

PERFORMANCE • DRAG • LAP & TRACK • TRAFFIC • SPEEDOMETER

Acceleration? Done.
Rolling acceleration and elasticity? Done.
1/4 mile? Done.
Lap timing and track recording? Done.
Top speed? Also done — assuming the road and common sense allow it.

HOWFAST is designed for drivers who prefer clear results, adjustable tests and useful data instead of optimistic guesswork.

Use your phone’s to measure:

• Acceleration times
• Rolling acceleration and elasticity
• 1/4-mile and custom-distance runs
• Speed and distance
• Maximum speed
• Lap and track performance
• Traffic movement parameters

Set your own speed ranges, distances and measurement modes. Start the test, complete the run and review the result in a clean, readable interface.

Made for fun.

HOWFAST is not professional certified measuring equipment and should not be treated as one. Results may vary depending on GPS signal quality, device sensors, mounting position, road conditions and measurement settings.

Always follow traffic laws, use the app responsibly and perform tests only in safe and permitted conditions. Physics is already unforgiving enough without adding legal consequences.
