I originally did this comparison with standard copy paper - which is 22# weight. After posting my results on Reddit, a developer asked me to try some different paper. What I learned - if you are going to use this app to measure PAR - it seems to be very accurate - even compared to the high end Apogee. HOWEVER - the developers should/need to mention that in order to get accurate results you MUST use 22# paper, which is not standard copy paper.
The instructions in the app say "Use regular matte white printer paper (22lb or 80g/m2) - 22lb paper is not the standard paper, and most users are most likely not going to have it readily available.

good Budget option then?
