Verdict

The call

The clearest difference is in-app purchases: SmaTan at none against チャレッタ's 1. SmaTan also leads on iOS requirement (11.0 vs 15.6). チャレッタ's advantage is review sentiment (71% vs 38%) and update cadence (every 3 days vs every 2 months). On price, ads and device support there is nothing between them.
