Verdict
The clearest difference is in-app purchases: Stelt Viewer at none against Hygrometer Barometer's 1. Stelt Viewer also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 7 months). Hygrometer Barometer's advantage is iOS requirement (13 vs 15.0). On price and device support there is nothing between them.
