Verdict

The call

The clearest difference is in-app purchases: Star Exposure Calculator at none against Monitor+'s 1. Star Exposure Calculator also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (13.0 vs 15.0). Monitor+'s advantage is ads (none vs shown) and device support (4 vs 2). On price there is nothing between them.
