Verdict

The call

The clearest difference is price: AClock at Free against 数日's $0.99. AClock also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). 数日's advantage is ads (none vs shown) and update cadence (every 8 days vs every 2 months). On in-app purchases there is nothing between them.
