光度計 LM-3000

I made a diffuser like it said. As im trying to get the measurements it keeps popping up telling me i need to build one. How can I use this app if the app wont let me use it.

I was surprised when this stopped working asking for purchase of a $7.99 app I just recommended this to someone and I’ve got to let them know that it’s not free like I told them

Great app! It works very well and no purchases!

Muy eficiente

Very useful, Thank you!

I have a $400 Sekonic Light meter wide by side with this app and the reading on this app is much higher.

I thought this was free. Should have read reviews first. Perhaps if you stated upfront that it is a free trial OR listed the cost upfront, I might have bought it. The trial did afford me the opportunity to find out that it will require a diffuser for accurate measurements, so at least that was a perk of the free trial.

Provides an objective measure of ambient light, giving me a sound basis for determining where I need more light — in my condo’s public spaces and in my own unit. Incredibly easy to use.

Loved it.... Until yet again purchase required when the listing doesn't say it upfront. So sick of bait and switch🙄😡

Greatly inconsistent readings. Every time the diffuser is removed and reapplied, the lumen readings are very different. They are inconsistent to the point of this app being unusable. I “cannot “ rely on the readings accuracy nor precision. I made, applied, and used the diffuser exactly as instructed. I was very exact that I placed the diffuser in the exact same position every time I reapplied it to my iPhone. After the diffuser wasn’t giving repeatable readings, I created a second diffuser and again received unrepeatable readings. Every time the diffuser is taken off and reapplied I received different readings. The difference in readings were sometimes over 100 lumens. We’ll there goes $7.99 down the drain.
