Verdict
The clearest difference is price: Zen Flip Clock at Free against Big Day's $0.99. Zen Flip Clock also leads on rating (4.7 vs 4.2) and update cadence (every 2 weeks vs every 6 months). Big Day's advantage is in-app purchases (none vs 3) and chart position (#33 vs unranked). On ads and device support there is nothing between them.
