Verdict
The clearest difference is price: MyZmanim at Free against Shabbos Clock's $0.99. MyZmanim also leads on rating (4.4 vs 2.4) and review sentiment (70% vs 31%). Shabbos Clock's advantage is update cadence (every 4 months vs every 8 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
