The app looks to be pretty neat and have cool additional designs, however it'd be nice to implement some sort of filter option to only show designs that I can make with the pieces I have. We gifted my son the Costco box of gravitrax pieces and it doesn't have all the pieces that some of the designs in the app have

The App is excellent, especially as it is basically free. Hopefully it will be updated with new Trax pieces. A few changes might be nice, like the limit on spirals and bounce angles. What would be nice is a change option and not just delete a tile. And the pivot handle makes it hard to see high bits from the side. Still excellent and even more so in conjuction with GraviSheets. A multitude of tracts to possibly make with easy steps to follow in the App.

I would say this is a really awesome app to have. I had the gravitrax advent calendar, and I wanted to test out some of the pieces. The only thing I will say about it is in real life you can start the marble anywhere otherwise in this you can't please add this function.🙏🙏
