# TrainSpotting vs TailTag

The clearest difference is in-app purchases: TailTag at none against TrainSpotting's 2. TailTag also leads on review sentiment (100% vs 87%). TrainSpotting's advantage is update cadence (every 3 days vs every 3 months) and rating (5.0 vs 4.8). On price, ratings volume and ads there is nothing between them.

Both are free to download. TrainSpotting sells 2 in-app purchases, starting at $1.99 per month. TailTag asks for nothing beyond the download.

TrainSpotting holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 87% of TrainSpotting's written reviews are positive against 100% of TailTag's, so the app with the better star average is not the one people write more warmly about.

TrainSpotting ships an update every 3 days, TailTag every 3 months. Both last shipped on October 24, 2026.
