Verdict
The clearest difference is update cadence: No.9 at every 6 weeks against Ouros's every 5 months. No.9 also leads on price ($1.99 vs $2.99). Ouros's advantage is chart position (#172 vs unranked) and ratings volume (82 vs 12). On rating, review sentiment, ads and in-app purchases there is nothing between them.
