Verdict
The clearest difference is in-app purchases: FIRE Countdown at none against DayInBook's 4. FIRE Countdown also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). DayInBook's advantage is ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). On price there is nothing between them.
