Features & Capabilities

Measure RPM with ease using Strobe Light - RPM! Turn your iPhone into a tachometer, adjusting strobe speed to check rotational speed of motors, fans, and more.

Strobe Light - RPM turns your phone into a powerful tool for measuring the speed of rotating objects. Using your phone's flashlight, this app acts like a digital tachometer. It allows you to measure the speed (RPM) of any rotating object by flashing light at the object in a specific pattern.

When the strobe light’s flash rate matches the speed of the object, it creates the illusion that the object is standing still. This helps you visually determine the exact rotational speed of the object, without needing to touch it.

How to Use:

  1. Mark the rotating object with something visible (a sticker or tape works well).

  2. Point your phone’s flashlight toward the object.

  3. Adjust the strobe speed until the object looks still.

  4. The RPM shown on the screen is the object’s rotation speed.

  5. You can save the reading for later reference.

Where It’s Useful:

  • Mechanics: Test fans, engines, or motors by measuring RPM.

  • Education: Ideal for physics experiments that require RPM measurements.

  • Industrial Use: Check the condition of rotating machinery.

  • Calibration: Ensure rotating devices are running at the correct speed.

Key Features:

  • Adjustable Strobe Speed: Set the strobe from 1 to 10,000 RPM for accurate measurements.

  • Quick Adjustment Buttons: Easily change the speed with buttons for +1, +10, +50, or +100 RPM increments.

  • Flash Sync: Ensures the light flashes at the correct frequency for accurate RPM readings.

  • History Tracking: Save and review your RPM data anytime for easy access.

  • Works in Low Light: Although user can obtain best results in the dark, still the app work in low-light conditions as well.

  • Simple and Energy-Efficient: The app’s interface is easy to use and doesn’t drain your phone’s battery.

  • Visual Tachometer: Acts just like a real tachometer, but using your phone’s flashlight and visual strobe technique.

Strobe Light - RPM makes it simple to measure RPM without any special tools or equipment. Whether you're working or just learning about rotational speed, this app turns your phone into an easy-to-use tachometer. Perfect for mechanics, hobbyists, students, and professionals alike!

User Reviews

The amount of ads this app shows is ridiculous. You have to watch an ad every time you start and stop the strobe! If you want to raise your blood pressure - this is the app for you.
