Verdict
The clearest difference is ads: CommsChanger at none against Global Rail's shown. CommsChanger also leads on device support (3 vs 1) and iOS requirement (13 vs 16.0). Global Rail's advantage is update cadence (every 5 days vs every 2 months). On price and in-app purchases there is nothing between them.
