Verdict

The call

The clearest difference is ads: Sumaddle at none against Orixo's shown. Sumaddle also leads on update cadence (every 3 weeks vs every 2 months) and rating (4.9 vs 4.7). Orixo's advantage is ratings volume (4.2K vs 767) and iOS requirement (11.0 vs 16.0). On price, in-app purchases, monetization model and device support there is nothing between them.
