Timepact is a visual timeline app for exploring history, prehistory, and deep geological time, all in one interactive view. See Time, Not Just Read It See when one thing began and another ended. Whether they ran side by side for a while, or whether a year, a decade, a century or a millennium lies between them. Dates become distances you can actually see. Three Time Scales Move seamlessly between three dedicated modes: Geological (from the Precambrian to today), Prehistoric (from roughly 2.6 million years ago through the Neolithic), and Historical (from the dawn of civilization to the present). Each mode adapts its scale, labels, and navigation to the timespan you're exploring. Built for Deep Time Pinch and zoom across scales spanning billions of years down to individual days. Scientific units (ka, Ma, and Ga) keep geological and archaeological periods clear and precise. Your Own Events, Organized Add personal or historical events, group them into collections, and tag them for quick filtering. The same event can live in several collections. Color-code tags to spot patterns at a glance, and save specific timeline views to return to later. Wikipedia Integration Search Wikipedia from inside the app and it fills in the event for you. Discover what happened on this day in history, pulled directly from Wikipedia. Data You Control Export and import your timeline data, with smart conflict handling when merging collections. Your data syncs across your devices through iCloud. Little Discoveries Along the Way Keep exploring: Timepact hides artefacts throughout the timeline for the curious to find. Multilingual
