For iPhone/iPod touch download - Back in Time for iPhone

Back in Time will take you on a stunning exploration of the history of our Universe, Earth, Life and Civilization. A journey through time where each event is documented with social and historical context, several images, an illustrative timeline and little-known interesting facts. Custom made animations bring those events to life, creating an interesting, immersive learning experience.

An imaginary clock will guide you through this quest, proposing a simple analogy: the entire Universe started 24 hours ago. The Big Bang, the source of time and space, is the first event in our journey – the clock reads 0:00 hours. Today, 13.7 billion years later, the clock reads midnight. In between is a sequence of key events that has brought us to where we are today. Explore them, place them in perspective, see how they relate and understand the connections.

We invite you to take a step back and see the whole picture.

:::: REVIEWS ::::

“...a beautifully executed lesson on the history of the universe and the evolution of life on earth. Great for high school students or parents who’d like to tutor younger children and enjoy a first-rate experience of their own...”
- Bob Tedeschi, The New York Times

“The iPad could use more apps like this one.”
- The Daily

“...the best iPad apps are those that combine coffee table-styled books with the fluid nature of the iPad’s interface. Back in Time is just that, it’s the story of the entire history of our universe made interactive on the iPad.”
- Casey Chan, Gizmodo (App of the Day)

“Back in Time is utterly gorgeous in its presentation. (...) The app is so easy to navigate that it is a delight to explore. Landka could scarcely have done a better job in putting everything together.”
- Gwen Phua, Appmodo

Beautiful App. Makes you wonder.

Awesome way of how to communicate and visualize time as it relates to life from the birth of the universe to today. Check out the last second and ponder.

Extremely Cool and Educational Too!

I absolutely love this app! Visually stunning, and intellectually stimulating! This is a great app for anyone who wants to understand the history of our universe according to current scientific knowledge. If you have ever read Stephen Hawking's "A Brief History of Time" you will be familiar with the content of this app, as well as the quality. But this app is so much more than that excellent book (and not directly related in anyway, as far as I know) but it takes that type of information and presents it in a beautiful interface that is fun to use and with its most excellent background music, surprisingly soothing! Give to this app as a gift to anyone who appreciates history, science or just wants to learn! Perfect gift for students of probably sixth grade on up through college too!

A superb tool for exploring the history of the universe

This fine app with its excellent graphics and very readable and accurate content is just a fine resource for grasping the evolution of our universe and the timescale of events. I teach people of all age groups about the history of the solar system and the universe, and it is extraordinarily difficult for them to grasp the time scale and sequence of events over billions of years. Relating it all to a 24 hour time scale that everyone can understand solves this problem elegantly, and Back In Time does this in great fashion with the two clocks that give the user an understandable roadmap to the past.. Quite an accomplishment.! The graphics are superb, and the navigation is exciting and stimulating. Great job.
