Works offline The globe, the maps and all the history ship inside the app. No account, no login and no signal needed. BUILT FOR HOMESCHOOL World Timeline gives kids the big-picture view a textbook chapter cannot: how the stories, civilizations and events of the past line up on one map and one timeline. It works alongside whatever history curriculum you use. The chronology is anchored to the Septuagint, placing Creation at 5554 BC and the Flood at 3298 BC. History is presented in an atlas-style voice and, where it is relevant, from a Biblical perspective, so families can use the lens that fits their studies. The app keeps growing. New events, people and map corrections arrive regularly, most of them without a store update. FREE, WITH AN OPTIONAL UPGRADE World Timeline is free to download, and the timeline, events and study tools are never interrupted. After you have explored the globe for a while, a pop-up now and then offers a one-time purchase that removes it for good, or a short optional video to keep going free. There is no subscription. Everyone who bought the app before it went free keeps the full version automatically. A NOTE ON ACCURACY History is big and the record is imperfect. Borders start from a public research dataset that maps political control at snapshot years, corrected by hand in hundreds of places; between snapshots the app shows the most recent map. Outlines known to be rough are drawn dashed and marked approximate. Dates and details are simplified for clarity, and reasonable sources disagree. Use World Timeline as a learning companion and a starting point for deeper study. If you spot something wrong, the feedback form on the About tab reaches me directly, and I read every message.

Verdict

The call
