Verdict

The call

The clearest difference is in-app purchases: Moon Phase Keeper at none against Surf's 2. Moon Phase Keeper also leads on ads (none vs shown) and update cadence (every 9 days vs every 6 weeks). Surf's advantage is ratings volume (1K vs 1) and chart position (#87 vs unranked). On price, rating and device support there is nothing between them.
