Good ap but still needs tweaking

I happily paid for the latest update hoping that the problem with limited height selection on the spiral would be addressed. Unfortunately it was not. It is not possible to create the layout on the cover of the Obstacle Set in the app as it uses two spiral heights which are not available. Other than that, after a little learning curve, I really enjoyed using the app to test-build different layouts. I welcome the Pro-Series parts and look forward to test driving them before I make additional purchases of the latest sets.

Amazingly robust - great paired with the toys

This app is truly incredible, and the fact that is free is crazy. I have spent plenty of money on the real sets, and it is great to try out the virtual components. What is most impressive is that the physics are fairly accurate compared to their real world counterparts.

The only complaint (and this is a small one) is the UX/UI when placing components. It would be nice to just add drag and drop from the lower bar, then have multitouch gestures to speed up placement.

For example, a few gestures could be (after a tile is selected):
- Two finger drag to rotate a selected tile
- Dragging finger moves tiles around
- Quick double tap (or persistent button) to bring up the old menu
- Have a persistent trash can icon and height tile toggle
- Once tile and height toggle is selected, dragging up or down would change height.

Anyway, I know these are not easy changes, but there could be a lot less tapping and that would make building the tracks even more fun.

Having said that, I frequently recommend this app and kudos to Ravensburger for creating and supporting it. I know it is kind of like advertising for them (and it’s worked well on our family!), but it is totally cool and adds value to the toy. Thanks again!

Great app with one serious but easily fixed flaw

This app is great even if you don’t have any of the physical pieces. However (this is the serious flaw), the music can’t be muted without muting the whole app. I want to hear the noises the UI makes but the music has already gotten on my last nerve.

Also, in the US we say “learned”, not “learnt”. “Learnt” is used outside of the US and Canada. So, devs, after you make it possible to mute the music separately you can update the US and CAN English regionalization files 😀👍
