Verdict

The call

The clearest difference is review sentiment: Weather4D Lite at 68% against World Now's 7%. Weather4D Lite also leads on rating (5.0 vs 2.4) and update cadence (every 2 months vs every 6 months). World Now's advantage is price ($3.99 vs $17.99) and ratings volume (27 vs 1). On ads, in-app purchases, monetization model and chart position there is nothing between them.
