User reviews

Good app with lots of potential

Can only measure frequencies up to 100hz. Would love to see some more advanced frequency counting or use of the slow motion camera to measure higher frequencies. The onboarding process is a bit much, could probably simplify that as using the app is very straight forward.

Response from developer

Hello! Fatigue is affected by pulsations up to 300 Hz and most often light sources pulsate at 100 Hz. This is due to the mains voltage and inexpensive light power supplies. Thank you for your feedback. We are constantly working to improve our product.

Not clear what it does

It outputs a number from 0 to 100. What does it mean? Main frequency? Intensity? Something else?

Response from developer

Hello! The pulsation of the light flux is measured as a percentage (%). 100% when the light source goes out completely and lights up, for example, at a frequency of 100 hertz, the light goes out and lights up 100 times per second. The human eye cannot detect this flicker, but it has a strong effect on fatigue.

Not at all accurate

This is totally off. Seems to be doubling flicker rates or more. Way off.

Response from developer

Hello! The application allows you to measure the ripple coefficient of radiation sources in the visible spectrum. It is important to keep your phone still. Hand tremors greatly affect the measurement results. The application does not turn your device into a professional measuring device, but allows you to determine the degree of pulsation of the light flux, its absence or presence.

It Works!!

Great to see that the light fittings I have always hated are actually flickering (& how much). I would like to take a Live Photo or short video within the app to show to the electrician (& husband!) to make it easier to record the results, with a name for each light fitting. But I can use screen recording as an easy workaround. Overall very happy.

Thank you for your feedback, functionality will be added in future updates.

Background information

I like the app but not totally sure what it is telling me. More strobing is bad I’m sure but more info on what should I be thinking about doing based on the readings I’m getting?

Response from developer

Hello! These measurements will help you understand how large the ripple (flicker) coefficient is. Anything with a value above 10-15% has a high ripple. The higher the coefficient, the stronger the effect on eye fatigue and the general condition of the body. The data obtained will help to choose lamps without flicker.
