For iPad download - Back in Time

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.

"The coolest history textbook you’ll find on the iPad"
- Bob Tedeschi, The New York Times

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

“...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 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

App Has Been Repaired and Now Works!


The app seems to be fixed now and is working properly as far as I can tell. Thank you, developer, for addressing these issues!


MARCH 2018:

The app just delivered an update a few hours ago. I launched the app after updating, and I cannot get past the first screen. I noticed another reviewer left a similar comment from this past November. Do not buy because this app doesn’t work — not even with the most recent update! I have an iPhone 6s Plus with the current iOS system.



Doesn’t work

Update for refund....agreed!!!!

The Keeper of the Ring


I disagree with any who say this isn't worth it. I'm a student in highschool, I very much enjoy learning new things, especially science, even scientific history. I also love music, not just modern pop or anything, I love more classical pieces as well, and Back in Time mixes both of the previous exquisitely. The music, if you ask me, fits the concept beautifully, as it feels like it's playing a description of how, as time has progressed, things have changed so much in our small part of the universe, yet have remained unchanged at the same time.
I sincerely hope that even more information will be added to this over time, though even if it isn't, I'll still love it.
Hope I was able to put into words well enough just how much I appreciate and cherish this wondrous app.
