Verdict
The clearest difference is in-app purchases: Dr.Style at none against SJ Chmod Calculator's 5. Dr.Style also leads on ads (none vs shown) and iOS requirement (14.0 vs 16.0). SJ Chmod Calculator's advantage is update cadence (weekly vs every 2 months). On price and device support there is nothing between them.
