Verdict
The clearest difference is in-app purchases: ArtPro MOS Diagnostics at none against Subnet Plus's 1. ArtPro MOS Diagnostics also leads on ads (none vs shown) and rating (5.0 vs 4.7). Subnet Plus's advantage is ratings volume (57 vs 1) and update cadence (monthly vs every 4 months). On price, monetization model and device support there is nothing between them.
