Not having the budget for a pricey light meter I looked into potential apps and found this one. I read the developers description and the app manual and followed the directions and violà - it worked like a charm!!! It was SO EASY to try out the app prior to paying the very small, very reasonable one-time price!! As long as you aren’t an idiot who lacks self-awareness, and take the 1-2 minutes to read the description and instructions, then this is the app for you!!
I don’t go out of my way to write reviews for apps, but this was so handy for me today. I used it to quantify what portions of the building I do maintenance for “feels dark” I was able to pinpoint mismatched/incorrect/burnt out bulbs and now I’m noticing that many of my illuminated LED down lights are past their prime and no longer giving off adequate light. Very reasonable amount of use for the free trial and the “battery life” on the meter indicating how many uses are left is a nice touch. Included video link and supporting documents are excellent and very handy. Went ahead and purchased the full battery knowing I will certainly put this app to use again in the coming weeks. Seriously well done on this 👍🏾
Free? When I first opened it I was required to make a light diffuser. Hmm okay. Easy enough. Once I got that attached to my iPhone the app popped up saying the meter ran out of battery and it would be $7.99 to purchase a lifetime battery. No options. My phone battery is 100% so that’s not the problem. This thing actually costs $7.99 if you want to use it. I wouldn’t be surprised if it continues to demand future purchases of something or other in order to use it. BTW, I have no idea if the light meter works. I never got that far. Update after developer’s response: I’m not confused about it being my phone battery. I’m confused how Apple lets you act like this is a free app but it’s only free to download, not free to use. It should be sold as an app for $7.99. It might even be worth it. But I’ll never know because I won’t trust a developer that says the app is free when it’s not. Update again after developer reply that this is a “try before you buy” app. No, it’s not. I didn’t get to try it. First it told me I needed the filter. So I made that. Then when I tried to use it, I got the message that the battery was empty and I needed to pay $7.99 for the lifetime battery. I never saw any light measurement at all. Why would I pay for this? You guys need to try using this from a phone not registered to one of you and see how it really works. Edit: I’m a systems analyst, software tester, support team member so I have some experience in this realm.
