Depends on what phone you have tbh. On my note 10+ vs my buddies actual lux meter it was fairly accurate up to about 60k. But yea over that things got funky.

Depends on a lot what app is used what phone etc I have used multiple apps at the same light same difference and readings were all over the place a cheap 20 dollar meter would probably be more accurate imo but I don’t use any of them so there’s that

Thats true as well. This is the only one I use as it was very close to the actual meter readings.

Shane from migro did a video on this app.
Said you can divide the lux by 90 to get an accurate par reading for a 4000k LED
I find that hard to believe though, because my spyderfarmer sf4000 is reading 67,000 lux at 12" below the board. According to Shane's algorithm, that would only be 744 PAR and I know my sf4000 is doing atleast 1000 or more in the center

I cant speak to whatever that guy said.

What I can speak to is my buddies par meter vs the app.
