# GraviTrax vs Twisty Rails

The clearest difference is review sentiment: GraviTrax at 74% against Twisty Rails's 33%. GraviTrax also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Twisty Rails's advantage is update cadence (every 10 days vs every 5 months) and rating (4.7 vs 4.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. GraviTrax sells 1 one-off in-app purchase and Twisty Rails sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Twisty Rails holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Twisty Rails has 16K ratings behind it against 156, so its average is the more settled of the two. Written reviews complicate that: 74% of GraviTrax's written reviews are positive against 33% of Twisty Rails's, so the app with the better star average is not the one people write more warmly about.

GraviTrax ships an update every 5 months, Twisty Rails every 10 days. The most recent releases landed on November 7, 2026 and November 11, 2026 respectively.
