Chronica: World History Atlas

Chronica is world history on one timeline, from the Big Bang to today. Pick any year and see what was happening across the world: its events, the people in power, and the map of the world as it was.

Everything lives on your phone. The timeline, the atlas, search and every entry work offline, with no signal and no account.

WHAT'S INSIDE
• 29,000+ events in war, politics, society, science, technology, medicine, religion, culture, exploration, sport and disasters
• 100,000+ people: rulers, scientists, writers, explorers, artists and athletes
• 56 political maps of the world, from 3400 BCE to 2024
• 33 maps of Earth's coastlines in deep time, back to 1,000 million years ago
• 65 eras, from the first moments of the universe to the Information Age

THE TIMELINE
Move from the birth of the universe through the dinosaurs, the first cities, Ancient Egypt, Rome, the Mongols and the Ottoman Empire, to Shivaji, the French Revolution, Indian independence, the World Wars, the Space Race and the internet. Each year shows its events and who held power around the world.

THE ATLAS
See the borders of empires, kingdoms and states at points across more than five thousand years, with the year's events on the map. Go further back and see Earth's coastlines as they were up to a billion years ago.

PEOPLE
Open a person to read who they were and follow them through the record: the events of their life, in order.

ON THIS DAY
The front page shows what happened on today's date in history.

SEARCH, SAVE AND LISTEN
Search by name, place or subject. Save entries to come back to. Have any entry read aloud. When you are online, open the full Wikipedia article and its pictures.

IN HINDI TOO
Chronica's screens are in Hindi, and a one-time download adds Hindi text for the events and people in the archive. The Hindi is machine-translated, and the app says so.

SOURCES
Chronica writes its own entries and checks every fact in them against Wikipedia. The rest comes from Wikipedia and Wikidata, with credit, and a Sources page shows where everything came from.

NO ADS
No ads, no account and no sign-in.

PRICE
Chronica opens with a five-minute preview. One purchase unlocks the full archive for good: nothing renews and nothing is charged again. It restores on any phone signed into the same Google account.
