Verdict
The clearest difference is in-app purchases: Zeta Cloud at none against PV Calculator.'s 1. Zeta Cloud also leads on update cadence (fortnightly vs every 7 months). PV Calculator.'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price and ads there is nothing between them.
