# GraviTrax Power vs Prusa

The clearest difference is update cadence: Prusa at every 5 weeks against GraviTrax Power's every 10 months. Prusa also leads on rating (4.0 vs 3.7) and ratings volume (117 vs 6). GraviTrax Power's advantage is review sentiment (75% vs 50%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Prusa holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Prusa has 117 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of GraviTrax Power's written reviews are positive against 50% of Prusa's, so the app with the better star average is not the one people write more warmly about.

GraviTrax Power ships an update every 10 months, Prusa every 5 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
