The Ravensburger GraviTrax POWER App opens up a new dimension for the GraviTrax marble runs. Together with the Gravitrax POWER Connect component, all POWER marble runs can now be controlled digitally. The POWER Connect connects the digital world to any GraviTrax POWER marble run. As soon as a connection has been established between the marble run and a mobile device, exciting functions such as remote control, programming, a stopwatch or sounds ensure diverse fun while playing and enable a playful entry into the world of programming. The electronic components of GraviTrax POWER establish invisible connections within the marble run via radio waves. There are transmitter and receiver components which can communicate with each other using three channels. With the new GraviTrax POWER app, players can now also control the marble run using their mobile phone or tablet and can program individual functions and processes. The functionality is based on sending signals from the app to the marble run and vice versa. This means that individual POWER components can be triggered independently of each other. These functions allow GraviTrax fans to influence the paths the marbles take, making themselves an active part of the marble run. More cool functions like a timer, sounds or signal counts give the app a playful character and provide even more GraviTrax actions. GraviTrax POWER app – the perfect connection between analogue marble runs and the digital world. Caution! Can only be used in combination with the GraviTrax POWER Connect components and other POWER components!

Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
