Verdict
The clearest difference is in-app purchases: RailTracker at none against SkyDiary's 1. RailTracker also leads on device support (4 vs 1) and iOS requirement (15.6 vs 18.6). SkyDiary's advantage is update cadence (fortnightly vs every 5 weeks). On price and ads there is nothing between them.
