Verdict
The clearest difference is price: Oneby at Free against Useday's $0.99. Oneby also leads on update cadence (every 2 days vs every 9 days). Useday's advantage is rating (5.0 vs 4.5) and iOS requirement (15.0 vs 17.0). On ratings volume, ads, in-app purchases and device support there is nothing between them.
