About this app

We all want more light in our lives. But how much is too much? And how much is not enough? That's where Photometer PRO comes in.

Our lux light measure app - Photometer PRO - helps you measure the brightness of your environment so that you can get the right amount of light for every situation.

👉 WHO CAN BENEFIT from our lux light measure app?

Whether you're a construction worker trying to compare different light levels after switching out your Halogen bulbs for LEDs, or just a flower hobbyist who wants to make sure each of your plants gets exactly the right amount of light, our lux light measure app - Photometer PRO - has got you covered. It even helps biology teachers practice photosynthesis!

✅INCREASE YOUR PRODUCTIVITY: whether you are a lighting designer, architect, electrician or just working from your home office - you can use the app to measure light levels and optimize lighting conditions, increasing productivity and enhancing the visual appeal of your projects

✅IMPROVE YOUR PLANT'S GROWTH: whether you are a horticulturist, greenhouse owner, or just a millennial (as we are!) who loves a little jungle in your home - you can use the app's PPFD calculator to determine the optimal light levels for plant growth, helping them create ideal growing conditions

✅SAVE THE ENERGY: our lux light measure app - Photometer PRO - helps homeowners, business owners, and lighting professionals select the right light bulbs and lighting fixtures, reducing energy consumption and promoting sustainable living

✅IMPROVE YOUR HEALTH: proper exposure to bright light, cool light, or a specific lighting schedule can significantly reduce the perception of stress and burnout. Light also plays a key role in setting and regulating the body’s biological clock (hormone function, like melatonin)

Ratings and reviews

Let me get this straight - this app comes with two separate sets of functionality. The first set is available for all to use. The second is behind a paywall with zero way to test the functionalities or even preview the design of the tools before payment. That's not the mark of a good business model that is respectful of the individual needs and preferences of those whom you're asking to invest in your product. Automatic out. Now to test the contenders before choosing one worth investing in.

Cool app. I use it for general light level comparison, not photography. Mostly to match various cheap "smart" bulb outputs around the house. It would be very nice to see Lumen added to the meter options rather than using the Calculator in the Pro version. As I move from a Pixel 4XL to a 7 Pro I noticed the readings are quite different. I need to look to see if there's some sort of calibration I need to do.

I don't know much about photovoltaics but, I wish I could have a logger that samples all day (maybe 10-12 hours). I would like to plot the result. I would also like to know the angle, time/date and location all for serveying my property for best location for cells. Location for me is optional but others would like it. Thanks! I forgot that it could be improved by add the ability to export samples to *. CVS files so people can integrate data into custom/or other types of applications. Sounds fun
