Verdict

The call

The clearest difference is update cadence: Tone Sphere at every 8 days against DEEMO's every 2 months. Tone Sphere also leads on iOS requirement (9.0 vs 11.0). DEEMO's advantage is ratings volume (5.1K vs 141) and chart position (#13 vs unranked). On price, rating, review sentiment and ads there is nothing between them.
