Verdict

The call

The clearest difference is in-app purchases: Election Explorer at none against Exoplanet's 7. Election Explorer also leads on iOS requirement (10.0 vs 13.0). Exoplanet's advantage is update cadence (every 2 weeks vs every 26 months) and device support (4 vs 1). On price and ads there is nothing between them.
