Have a look for free, but you won't enjoy this app unless you get the paid version, which is WELL WORTH THE LOW PRICE. The ads interrupt viewing as often as once a minute, making the free version useful only as a demo. I wish I'd looked for something like this while reading Red Mars. It would have provided tremendous enrichment.

Thank you. That is correct - the free version is a demo version. You can test all functions and upgrade to a full version if you like the app. Kind regards.
