I have most, if not all, of your programs! I love them all, and recommend them to anyone interested in astronomy, wildlife, paleontology, and wildlife.

Solar Walk

i like it but i have to spend money in the game 4 stars

Been using this apps for many years and the stuff I learned from studying the model is indispensable

don’t waste your money on this, very unrealistic, limited, expensive waste of space of a game

Because it is so realistic.

Just paid for the hi resolution earth and everytime it downloads the app only stays at the intro screen and I end up having to delete the app entirely and re download. Please fix this I don’t want to feel like I just wasted my hard earned money.

It’s so realistic and precise about the planets

Stops at splash screen and does not continue to open.

This was the better of the two Solar Walk versions. The interface was far better. Unfortunately, this version has stopped working.
