Tinker Box
this is one of the most amazing apps I have ever had but I have a few more ideas you could possibly add:
1. add some magnets and magnetic stuff like different kinds of magnetic balls.
2. definitely add power switches to some of the objects like a speed adjuster for the conveyor belt, fans, and motors
3. i would love it if you would ad more space to play in
4. more puzzels
thanks, i recommend this app for anyone who likes legos, puzzles,or K-NEX
