Earth Primer

thank you for creating this app. it is making complex things playfully explorable. i can teach geology and geomorphology to my 5 year old daughter as much as to adults with this app. maybe some meta-material about the used algorithms and models would be a great addition for using it in professional teaching.

I enjoy this interactive book very much! Amazing.

Our school had this on our Macs, so I decided I wanted to purchase the iPad version just so I could use it on my own. I hope this app always remains available; it’s too invaluable a tool for illustrating geomorphology to lose.

This is one of the best games I’ve played! I will like if the game had more feature but is still a good game

I work in a museum and I got an old iPad just so I could share this app with children. It's fantastic. I really appreciate that it only requires iOS7, that really opens up the door for educators to make it accessible to low income communities. Thank you for the work and creativity that went into this app.

The best game ever but I think it would be awesome if you make the right climate and animals and people start to make city’s and get more and more advanced.So gust a suggestion.

For the first 10 minutes it was fun, but it got old really fast. I would not recommend.

I spend a lot of time searching for and playing with math / science apps. It's part of my job. This one jest blew my mind in terms of the app itself and in terms of the possibilities it suggests for further related educational media. Perfect integration of instruction and play. This one has it all right. Clear instruction, deep dynamic simulation, excellent emergence of geological land forms and related ecosystems... it really is excellent! Suggestions: It would be nice to be able to adjust the rate at which time passes,. Maybe even pause time as needed. I'd also love slightly larger surface in sandbox mode. I would love to be able to run a larger landscape at a lower frame rate/ slower time rate.

This app helped out greatly with my seventh grade science class. It helps students visualize and visually interact with ideas that static images can’t quite achieve. The graphics and interaction are truly fantastic in this app represent some of the best the App Store has to offer. Great work!

BUY THIS. WOW. This would be worth every single penny even if it was $20. I've never in my life seen something so educational so incredibly well designed in both presentation and execution. Absolutely incredible. 17 out of 10. I truly hope to see more in the future.
