I really love the concept of this app and I can’t wait to be a member and start using it. But unfortunately your system doesn’t recognize an US number. It’s so annoying. If so can you not force me to use a phone number then? Please fix.

A stunning app! For full view of map, I prefer tablet to show up.

I sense this will be something completely huge in years to come. I get it that the contents are of big-History scale, from Big Bang to modern days, all sorted out via timelines or knowledge graphs or maps, and the maps are best described as temporal (think of google maps but with 5000 years of history atop each year’s temporal map). Will there be an English edition soon?
