Unlimited History

All of time, with a source behind every claim — and your own life drawn on it.

iPhone iPad

Coming soon to the App Store for Mac, iPhone, and iPad.

Put the age of the universe, geological time, civilizations, lives, and today on one continuous, zoomable axis. Every claim carries a citation, every date keeps the calendar and precision it was published with, and contested history stays contested.

Start with you

• Your life on the axis — three nested bands: your life, the written record, all of time. Each band is the whole of the one above it, drawn as the bright sliver at its edge.
• The world you were born into — temperature, emissions, patents and languages described, in your birth year and now, each with its source.
• Alive the year you were born — the recorded lives that overlapped yours, and what falls on this day.
• Nothing invented — the app draws nothing about you until you give a birthday.

One axis, every scale

• Zoom from the universe to a day — move continuously through billions of years instead of jumping between disconnected timelines.
• See what the scale allows — records resolve as you get closer, while the geological chart keeps deep time readable.
• Read the ruler two ways — years before now, or the cosmic calendar with all of time as one year.
• Progress as measured streams — population, output, patents, languages described and what was burned, drawn together over the written record, each keeping its own scale.

The evidence stays attached

• A source behind every claim — follow a record to the citation and the passage that supports it.
• Dates keep their meaning — calendars, ranges, approximate dates, and published uncertainty remain visible instead of collapsing into false precision.
• Disagreement remains disagreement — contested dates and interpretations are marked, with the competing positions kept side by side.
• Disaster catalogs name their rule — earthquakes, eruptions, floods, famines, outbreaks, and conflicts say why each record was included.

More than one point of view

• Choose a lens — Global, US, and European perspectives can change which records are surfaced and how a span is named, but never move a fact.
• Compare two readings — place perspectives beside one another while each keeps its own name, evidence, and date envelope.
• Follow the strands — read geological, climatic, biological, hominin, human, and institutional history separately or together.

Life inside deep time

• Read people as lifespans on the same axis as the events around them, opening on the year you were born.
• Place fossil first and last appearances against the geological chart, with dating envelopes and occurrence counts intact.
• Print the corpus as a Book of Centuries: one cited page per division.
