Camera RPM Meter User Reviews

Top reviews

Poor performance

Light strobe is inconsistent and camera is laggy.

Trash

So many timed adds to click through, I deleted it. After 1 minute, I still wasn’t using the app. I have no idea if it works. I’m not going to click through ads every time I use it.

Ads Only

Did not make it past the ads. It forces an add down your throat every time you change screens or hit a button. Deleted the app before I even got a chance to see if it would do what I wanted.

Too many adverts

This is just a bundle of adverts with an app thrown in to disguise the fact that it’s just a load of adverts.
Every touch of the screen brings up another lengthy advert
DELETED.

PERFEITO!!

Perfeito! Funcionou como eu esperava

Privacy Violation

It took too long to object to all the legitimate interests so I was unable to use the app.

用不了

进去后没有任何功能

Full power of

Revolution I mean the whole screen occupied by the adv before you can do anything. Great work developer for adv.

Works

Y

Doesn’t work.

Downloaded it, immediately tried to make it strobe my phone’s light….. nothing. Doesn’t work as advertised.
Also - horribly frequent ad popups make it unusable. Obnoxious.

Response from developer

Thanks for your review. To use the app correctly, make sure to use it in a sufficiently dark environment and with the flash of your mobile phone pointing towards the surface of your rotational device. When the flashing light (flash per minute) and the revolutions per minute of the device match, the mark on the device will look solid. If you have any further questions or suggestions, please contact us at codebuster2021@gmail.com. We appreciate your patience and support!

Não presta

Não perca tempo não funciona

Worst app ever

We understand that apps are financed through advertisements but this app ??? … where is it actually? 95% of it are ads … impossible to validate the actual features the app is supposed to have.

Response from developer

Thank you for your feedback! We understand that ads can be frustrating, but they help us keep the app free for users. That said, we strive to balance the ad experience with usability, and we're always working on improving it. The app's core features are fully functional, and we encourage you to explore them. If ads feel overwhelming, we offer an ad-free version through a subscription. Additionally, we’re excited to share that a "Remove Ads" option will be included in our next update to improve your experience further. If you have any questions or need assistance, please don’t hesitate to contact us at codebuster2021@gmail.com. We appreciate your understanding and support!

No help

Don’t know how to use it - no help

Response from developer

Our app is designed to help you find the RPM (rotations per minute) of a device using blinking light. Here's how it works: Adjust the blinking speed using the buttons provided. When the blinks per minute match the device's rotations per minute, the marked point on the device will appear stationary. This works best in suitable darkness as the blinking light needs to be clearly visible. Alternatively, you can also use your camera to calculate RPM based on frames per minute. If you have any questions or need further help, feel free to reach out to us at codebuster2021@gmail.com. Thank you for giving our app a try!

App

dont work

Response from developer

For RPM measurement, use the blinking light feature: Adjust the blinking speed to match your device's rotations. When the device's mark appears stationary, you’ve found the RPM. Ensure you are in suitable darkness for better visibility. Alternatively, you can use the camera frame-per-minute feature for certain tasks. If you're still facing issues, please reach out to us at codebuster2021@gmail.com so we can assist you directly. Thank you for trying the app, and we hope to improve your experience!

Not great

Sorry. It’s a valiant effort and I can see how it should work. However on my iPhone SE2020 its not great. Possibly messed up by CPU interrupts? Maybe good on other devices? Deleting now.

Unleash a firestorm of ads!

Nonstop ads. Virtually impossible to get to the app itself. No instructions whatsoever and it’s not clear that the app works - no success with the strobe function- the camera option at least seemed to work but the results were suspect given a device with a known RPM range

Response from developer

Thank you for your feedback! We sincerely apologize for the inconvenience caused by the ads. Ads are essential for us to keep the app free for users, but we understand your frustration. We're actively working on improving the balance between ads and usability, and an option to remove ads will be available in the next update. Regarding the app's functionality, the strobe feature requires both the mobile device and the rotating object to be in a suitable dark environment. Adjust the blinking speed using the controls until the mark on the object appears stationary—this indicates the RPM. The camera mode is an alternative, but accuracy depends on lighting and frame rate. If you have any further questions or suggestions, feel free to reach out to us at codebuster2021@gmail.com. We're committed to improving the app and your experience. Thank you for trying our app!
