Explain 3D: How things work

In the newer iPhones the the disruption is hidden partially. I cannot read half words to understand and teach my kid. Please fit to size

The app really doesn't do anything. Not at all worth the money. No real interaction and zooming in and out is way too glitchy.

Simulations are not accurate and are not detailed enough its a great idea but needs a lot more improvement I just waisted 4 dollars.

I may view this more favorably than the average, because this is the sort of thing I bought an iPad for. Stand-alone (as opposed to internet-connection-dependent) animated virtual reference app I can have on hand as I study how things work. Mind you, this high-rate review is for the concept. And my expectations that the improvements that can be made, will be. More items, particularly of home and car items. The finger controls could use some fine-tuning, especially the zoom function. And fix that to-small-to-read information text box.But all-in-all, well done.

Cool concept, good models, reasonable selection of topics...I just can't read the text on an iPhone. Haven't found a way to expand the text boxes so they're readable.
