Verdict
Trainline and KeyNest Agent both sit at 4.9 stars, but that hides the real split: 75% of KeyNest Agent's written reviews are positive against 29% of Trainline's. KeyNest Agent also leads on ads (none vs shown) and monetization model (free vs ad-supported). Trainline's advantage is update cadence (weekly vs every 3 months) and ratings volume (11K vs 1). On price, rating and in-app purchases there is nothing between them.
