No. You have to test app readings with camera meter reading under different light scenarios.
What exactly "better phone" means?
I had free light metering app on iPhone 4 which is very limited device and it worked so good, My Seconic in the the storage since then.
I don't care what they read. I just want to know if 2 phones (say 2 Iphone 14 pro) loaded with the same ligh meter app do they give you the same reading. I don't care about comparing them to the camera or a real light meter. Or how accurate they are.
If you prefer:
The quality of your results also depends on the quality and features of the phone.
And it is difficult to evaluate how suitable your phone is, without trying the app.
It has been proven that the better the phone the more accurate the results would be…!
I have question for those who use light meter app. If you use 2 phones of same make and model and load the same app do they read the same? I can't do the test but I think that they don't.
But if you have 5 guys with 5 cameras compare their meter readings, you will likely to find one or more which are in disagreement with the others.I don't care what they read.

Why would you then automatically expect 5 guys with 5 phones with metering apps to all be in agreement?...ergo, the need to compare a new app in a phone against a known (existing camera) meter with processed film results corroborating the accuracy of the camera's meter.
The fundamental issue is that the app would have to ASSume that the photosensor of every different model (if Apple) or of every different make and model of non-Apple phone has identical electrical characteristic with virtually no variation caused by sensor or by supportng circuitry that converts sensor data to image data, for there to be zero need for a correction factor.
I am sure the apps being software, so there is no variation with one apps. I want to know how consistent are the phone hardware. Camera meters or hand held meter have the advantage of the same company makes the hardware as well as the software/firmware for them and they do calibrate them in the factory to take into account of hardware variations. No such calibration is possible with the phone app. If any you the user has to do it yourself.
NO, a good software programmer would have different sets of parameters or code based on the iPhone used so that the user would not have to make any adjustment. This is done in software development for decades, nothing new or adventuristic about it.

I have used myLightMeter Pro on three different iPhones, 5,7 and 11 and never saw any difference in how it read a scene. The camera in the phone has improved and the lenses are better but it hasn’t made any difference in how it meters. There have been updates to the app and it’s more reliable. It has always been close to my hand held meters, I just don’t use it much because if I have my camera, I have a meter.
Little late to this thread, but I've had really good luck with the Lightme app for iOS. Exposure readings are dead on compared to my in camera light meters. I paid a small fee (I think $10) to support the developer, but it has a decent amount of features that made it well worth it to me. Always nice to have on hand just in case I'm without a light meter.
It works fine. Just a little tricky to hold both my phone and mamiya 645.
