Verdict
The clearest difference is price: SkyDot at Free against RailsMaps's $4.99. SkyDot also leads on device support (3 vs 1). RailsMaps's advantage is ads (none vs shown) and chart position (#145 vs unranked). On update cadence, in-app purchases and iOS requirement there is nothing between them.
