Verdict

The call

The clearest difference is review sentiment: Emosign at 100% against Sumomo's 13%. Emosign also leads on rating (5.0 vs 2.7) and ads (none vs shown). Sumomo's advantage is update cadence (every 6 days vs every 2 months) and ratings volume (9 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
