Frequently Asked Questions

Like every other vertical feed you already use — except every card is a real historical battle. You open Battle Lens and land on a full-screen battle: image, name, date, location, outcome. Swipe up for the next, down for the last. Tap a filter to narrow the feed by era, region, war, or outcome. Tap a battle for its full dossier. The format you already know, applied to ~3,500 years of world history.

4,763 historical battles spanning ~3,500 years, from c. 1500 BC (the Battle of Megiddo) to the present day. The dataset covers 76 wars, 396 commanders, and 10 eras — Ancient through Modern, with dedicated eras for the American Civil War and the Interbellum period (1918–1939).

Yes — the whole core experience. All 4,763 battles and 3,136 images ship inside the app, so the feed, the details, the stats, the filters, and the commanders browser need no connection at all. Two things do use the internet: the map's background tiles, and Pro audio narration, which is downloaded on demand rather than bundled. Download the narration tracks you want while you're online and they'll play back offline afterwards — everything else already works with the radios off.
