# FLEXHOTEL vs Rail Ninja

The clearest difference is review sentiment: FLEXHOTEL at 100% against Rail Ninja's 32%. FLEXHOTEL also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.5). Rail Ninja's advantage is rating (4.8 vs 4.3) and ratings volume (6.2K vs 3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Rail Ninja holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Rail Ninja has 6.2K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of FLEXHOTEL's written reviews are positive against 32% of Rail Ninja's, so the app with the better star average is not the one people write more warmly about.

FLEXHOTEL ships an update every 3 months, Rail Ninja every 3 weeks. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
