Verdict
The clearest difference is in-app purchases: Instant Cal at none against 投屏助手's 6. Instant Cal also leads on update cadence (every 2 weeks vs every 4 months). 投屏助手's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
