Verdict
The clearest difference is rating: Catenary Maps at 4.3 against Interrail Rail Planner's 2.7. Catenary Maps also leads on monetization model (free vs free with in-app purchases). Interrail Rail Planner's advantage is ratings volume (1.6K vs 3) and review sentiment (24% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Catenary Maps holds the better App Store score, 4.3 against 2.7. That said, the two scores are not equally well evidenced: Interrail Rail Planner has 1.6K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 24% of Interrail Rail Planner's written reviews are positive against 0% of Catenary Maps's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 20, 2026 and October 16, 2026 respectively.
