Verdict
The clearest difference is rating: Flip Clock at 4.6 against Big Clock's 2.3. Flip Clock also leads on update cadence (every 3 weeks vs every 31 months) and ratings volume (69K vs 4). Big Clock's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
