Verdict

The call

The clearest difference is ads: Nu at none against Saffron Square's shown. Nu also leads on review sentiment (33% vs 0%) and monetization model (free vs ad-supported). Saffron Square's advantage is update cadence (every 3 months vs every 15 months). On price, in-app purchases and device support there is nothing between them.
