Strobe Light vs Strobe Light

Strobe Light - RPM turns your phone into a powerful tool for measuring the speed of rotating objects. The app works like a digital tachometer and offers two measurement modes: Strobe Light and Camera. You can measure the RPM of fans, motors, wheels, and other rotating devices without touching them. In both modes, the same stroboscopic principle is used. When the flash rate or camera frame 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 with high accuracy. Strobe Light Mode Using your phone's flashlight, this mode flashes light at the object in a specific pattern. It works best in a dark or low-light environment and is ideal when you want a quick RPM reading with the built-in flashlight. How to Use (Strobe Light): Mark the rotating object with something visible (a sticker or tape works well). Point your phone's flashlight toward the object. Turn on the strobe using the power button. Adjust the strobe speed using the + and - buttons until the object looks still. The RPM shown on the screen is the object's rotation speed. You can save the reading for later reference. Camera Mode Camera mode uses your phone's camera to show a live preview at a set frame rate (FPM — Frames Per Minute). When the frame rate matches the object's RPM, the rotating object appears frozen on screen. This mode is useful in well-lit conditions when you want to see the object clearly while tuning the speed. How to Use (Camera): Open Camera mode from the home screen and allow camera permission. Point the camera at the rotating object. Adjust the frame rate using the + and - buttons until the object looks still. The value shown on the screen is the object's RPM. Use the flash button if you need extra light in darker areas. Save or reset your reading anytime from the bottom buttons. 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. Maintenance: Compare readings over time using saved history. Key Features: Two Measurement Modes: Choose Strobe Light or Camera from the home screen based on your environment and preference. Adjustable Strobe Speed: Set the strobe from 1 to 10,000 RPM for accurate measurements. Camera Frame Rate Control: Set camera preview from 30 to 14,400 FPM for precise visual tuning. Quick Adjustment Buttons: Easily change the speed with buttons for +1, +10, +50, or +100 RPM increments in both modes. Flash Sync (Strobe Light): Ensures the light flashes at the correct frequency for accurate RPM readings. Built-in Camera Flash (Camera Mode): Toggle the flash on or off for better visibility in low light. Save and Reset: Save current RPM readings with a custom title or reset to default anytime. History Tracking: Save and review your RPM data anytime for easy access from the menu. Works in Different Lighting: Strobe Light works best in the dark; Camera mode works well in normal and low-light conditions. Simple and Energy-Efficient: The app's interface is easy to use and designed to be practical for everyday measurements. Visual Tachometer: Acts just like a real tachometer using visual strobe techniques with your phone's flashlight or camera. Strobe Light - RPM makes it simple to measure RPM without any special tools or equipment. Whether you prefer the classic flashlight strobe method or the new live camera preview, this app gives you flexible and accurate RPM measurement in one place. Perfect for mechanics, hobbyists, students, and professionals alike.

LightUP is a strobe you can set exactly. Screen and camera torch flash together, from one slow beacon a second up to 30 flashes per second — and you choose the rate, rather than picking from a handful of speeds. Everything runs on your phone. No account, no sign-up, nothing uploaded, no network at all. SET THE RATE, EXACTLY A big dial shows the flash rate in Hz and in flashes per minute. Drag it, nudge it in fine steps, or tap the tempo out and LightUP matches the beat. Flash width controls how long each flash stays lit — short and sharp for a hard club strobe, wide and soft for a gentle pulse. Presets cover the usual jobs: a dance-floor pulse, a slow beacon for being seen, a fast blue police flash, an amber hazard blink, and a soft candle flicker. TACHOMETER: MEASURE HOW FAST SOMETHING SPINS Light a spinning fan, wheel, motor or drone propeller and raise the rate slowly. When the flash rate matches the rotation, the object appears to stand still. LightUP converts that into RPM, and lets you set the blade count so a three-blade fan is not reported at three times its real speed. It also shows the harmonics — the whole multiples where the object looks equally frozen — because hiding that ambiguity would be a comfortable lie. Start slow; the first rate where it freezes is the true speed. FLASHING LIGHT SAFETY, TAKEN SERIOUSLY Flashing light can trigger seizures in people with photosensitive epilepsy, including people who have never had one and do not know they are susceptible. LightUP is built around that rather than burying it in a disclaimer: - It starts at 2 Hz, never at a fast rate. - The 15–25 Hz band, where reactions are most commonly provoked, is marked in orange on the dial, and the readout turns orange inside it. - A plain warning appears before the first flash of every session, not once ever — the person holding the phone may not be the one who read it. - While it runs, the entire screen is the stop button. Hunting for a small control in a flashing room is exactly when you need it to stop instantly. Please do not point a strobe at anyone who has not agreed to it, at drivers, at cyclists, or into a crowd. WHAT YOU GET FREE - The full strobe, screen and torch, 0.5 to 30 Hz - Exact rate control, fine steps and tap tempo - The party and beacon presets - The complete safety guidance and the marked risk band WHAT PRO ADDS - Tachometer mode with RPM readout, blade count and harmonics - Colour strobe: amber, red, blue, green and magenta - Flash width control for sharper or softer pulses - The police, warning and candle presets HONEST LIMITS The camera LED cannot physically switch faster than about 10 times a second. Above that the screen carries the strobe alone, and LightUP says so instead of pretending the torch keeps up. Long sessions make the phone warm — that is the LED, and it is normal. The tachometer is a genuine stroboscopic measurement, but it is only as good as your eye and a steady hand. It is a field reading, not a calibrated laboratory instrument. PRIVACY No account, no analytics, no network access whatsoever. Camera permission is used for one thing only: switching the torch LED on and off. The app never opens the camera, never previews, and never records. SUBSCRIPTION LightUP Pro is available as a weekly subscription at $3.99 with a 3-day free trial, or a yearly subscription at $17.99. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period. You can manage and cancel your subscription in your App Store account settings after purchase. Any unused portion of a free trial is forfeited when you buy a subscription.
