Verdict

The call

One Day and Countdown Widget Calendar both sit at 4.7 stars, but that hides the real split: 100% of One Day's written reviews are positive against 60% of Countdown Widget Calendar's. One Day also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Countdown Widget Calendar's advantage is update cadence (fortnightly vs every 12 months).
