Verdict
The clearest difference is review sentiment: Ovul Simple at 100% against Harmony's 36%. Ovul Simple also leads on in-app purchases (none vs 18) and rating (5.0 vs 4.7). Harmony's advantage is ratings volume (10K vs 4) and update cadence (every 6 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
