Verdict
The clearest difference is ads: HiScreenCast at none against Instant Cal's shown. HiScreenCast also leads on iOS requirement (12.0 vs 15.0). Instant Cal's advantage is update cadence (every 2 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.
