NOTE: The App is just for iPhone with flashlight. It doe NOT work on iPad, iPod touch or any iOS device without flashlight. Description: Using this App, you can control the flashing on/off speed of your phone flashlight between 1Hz to 130Hz. In another word, this App makes your iPhone into a strobe light. What's the Application then?! You can use this App to use your iPhone as a tachometer that measures the speed of any rotating object. How to use it? Suppose you have a fan and need to measure its speed (RPM). Turn on the fan in a DARK environment, launch the App on your iPhone (that has flashlight). Manually tune the speed using the main slider of the App to see the rotating object looks almost not moving. Then, start fine tuning using the three buttons in the App to get the exact speed. At this point the rotating object looks like stationary! But, it is moving! So, never touch the moving/rotating object during your test! Features: - Slider to adjust strobe light speed between 1-130Hz (60-7800RPM) - x2 and ÷2 buttons for quick adjustment of flashing speed - 3 Buttons for fine tuning of the speed up to 2 decimal: 0X.00, 00.X0, 00.0X - Textfield to manually enter the speed in RPM (tap on the speed label) - Button for light and dark background option - showing the speed in both Hz and RPM - simple and easy to use!!

Verdict
The clearest difference is update cadence: Autodesk Fusion at monthly against Strobe Light Tachometer's every 7 months. Autodesk Fusion also leads on rating (4.5 vs 4.2) and ratings volume (4.1K vs 277). Strobe Light Tachometer's advantage is iOS requirement (7.0 vs 13.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Autodesk Fusion holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Autodesk Fusion has 4.1K ratings behind it against 277, so its average is the more settled of the two. Written reviews complicate that: 63% of Strobe Light Tachometer's written reviews are positive against 59% of Autodesk Fusion's, so the app with the better star average is not the one people write more warmly about.
Strobe Light Tachometer ships an update every 7 months, Autodesk Fusion monthly. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
