Tyokiie: Offline Wiki+Timeline - Google Play

Tyokiie is an offline-first Wikipedia reader and reference toolkit. Search and read encyclopedia articles with no account, no sign-up and no distractions — once a language is on your device, you can explore without a connection.

★ Parallel Timeline — see history side by side
Tyokiie's flagship feature lays the past out as parallel horizontal lanes, so you can finally see who ruled where at the same moment. Europe, East Asia, the Middle East, plus Scientists, Composers and Rulers — each reign and lifetime drawn to scale on a shared year axis, with portraits from Wikimedia Commons. Tap any entry for a summary card, then jump straight to the full article.

Two ways to look at time, one tap apart:
• History view — an evenly-spaced year axis reaching back to 3400 BC, the dawn of the written record.
• Cosmic view — a logarithmic "deep time" axis that fits everything on one screen: the Big Bang (~13.8 billion years ago), the forming of the Earth and Moon, the age of dinosaurs and the rise of humankind, right up to today.

★ A reader built for reading
• Full-text search across the offline database
• A clean, modern article view with an optional serif reading mode
• Reading themes to suit any light — Day, Sepia, Night, Nord and more, including Chinese Ink and Rice Paper
• Collapsible sections and a compact table of contents
• Link Glosses: cross-language annotations on wikilinks to give language learners a helping hand

★ Everyday tools
A built-in scientific Calculator and a Unit Converter, for when a quick answer is all you need.

★ Speaks your language
The interface, the timeline and the tools are localized into 15 languages — read and explore in English, 中文, Español, Français, 日本語, العربية and more.

★ Built to respect you
Offline-first and private by design. No account, no cloud lock-in — just fast, quiet access to human knowledge.
