Verdict
The clearest difference is in-app purchases: 看空气 at none against Spool Master's 2. 看空气 also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Spool Master's advantage is update cadence (every 3 days vs every 9 months). On price and device support there is nothing between them.
