Verdict
The clearest difference is in-app purchases: FIRE Countdown at none against Fukurin's 1. FIRE Countdown also leads on update cadence (every 2 weeks vs every 6 weeks) and device support (3 vs 1). Fukurin's advantage is ads (none vs shown). On price and iOS requirement there is nothing between them.
