Verdict
The clearest difference is in-app purchases: Xenon Smart at none against Whenlyy's 1. Xenon Smart also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.6). Whenlyy's advantage is update cadence (every 2 months vs every 17 months). On price and ads there is nothing between them.
