The application is a psychrometric chart. It accurately calculates and displays relevant thermodynamic air & water vapour mixture properties. Supports both SI and imperial unit systems By sliding the reticle within the graph the properties values for each corresponding graph point are instantly updated and displayed in the respective fields. In particular the following properties are shown: Dry-bulb temperature, Relative humidity, Wet bulb temperature, Specific enthalpy & Dew point. Additionally ISO-7730 PMV/PPD thermal comfort parameters are calculated.

Verdict
The clearest difference is update cadence: Psychrometry Chart at every 2 weeks against NagareVisualizer's every 3 months. Psychrometry Chart also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.6). NagareVisualizer's advantage is price ($0.99 vs $1.99). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
