We bought this game a year or so ago. It was my son’s favorite app. But a couple months ago, it suddenly stopped working. You couldn’t load a profile or make a new one - the game would just crash. We’ve uninstalled and reinstalled it and that didn’t help. Reached out to the developers and they said to try an uninstall and reinstall and when I said that I’ve tried that, they offered a refund, which was kind of them. But since there doesn’t seem to be any recent reviews for this app, I thought I should let you know that if you buy it, there’s a good chance it just won’t work.

Hey tiny bob I like everything but I think you should be able to make machines I think this because I get tired of just playing with 6 machines and this also on the wheel and axle one the square wheels I think should work I thought it would look pretty cool and on the pulley one I can't bring up the planet why and sometimes I can't bring up the other things I think your app is cool I like everything thing except for the things I listed up top

This app really plays like a set of old school toys. You have wheels, levers, screws, inclined planes, wedges, and pulleys — and a little playground for each one. Like real toys, there’s no real object — you just mess around with them and see what happens. There are enough fun little touches to really reward experimentation and, basically monkeying around — in a good way. My daughter found it immediately engaging — as did I.

We love how the app doesn't have scores to keep or levels to break through. It's just open for you to play and explore. It's like when my son first got his legos he just 'tinkered' with it with no goal. He stared at the fish tanks in the screw scene for a long time and got really excited when little boats started dropping in! A lovely app!
