Verdict

The call

The clearest difference is ads: Nihongo at none against Japandix's shown. Nihongo also leads on update cadence (every 6 days vs every 5 months) and ratings volume (1.9K vs 1). Japandix's advantage is rating (5.0 vs 4.8) and review sentiment (100% vs 91%). On price, in-app purchases, monetization model and device support there is nothing between them.
