DevDocs – Offline Dev Docs

The Dash for Android — finally here.

Browse 200+ developer documentation sets completely offline. Kotlin, Python, JavaScript, React, Docker, Rust, and more. Download once over Wi-Fi. Search, read, and bookmark forever — no internet required, no browser needed, no distractions.

━━━ WHY DEVDOCS? ━━━

Dash has served 1 million+ macOS developers for years. Android has had nothing comparable — until now. DevDocs brings the same offline-first philosophy to Android phones and tablets. Download any documentation set once, and it lives on your device permanently. No signal? No problem. Airplane mode? Still works. Server room with no internet? Perfect.

Browser-based docs fail the moment you lose signal. DevDocs never does.

━━━ HOW IT WORKS ━━━

1. Open the Store tab → search or browse by category
2. Tap a docset → tap Install
3. DevDocs downloads and indexes it locally
4. Open the Library tab → tap any installed docset
5. Search globally across everything, or search inside one docset
6. Tap a result → instant offline reader

From install to reading in under 60 seconds.

━━━ PRIVACY ━━━

DevDocs uses the internet for one purpose only: downloading docsets. Everything else — reading, searching, bookmarking, navigation — is 100% offline and always will be. No account. No ads. No tracking. Your reading history, search queries, and bookmarks never leave your device.

━━━ FREE — FOREVER ━━━

DevDocs is free and will remain free. If it saves you time, helps you learn, or gets you through a flight with actual productivity — consider leaving a small tip from the Support screen. Entirely optional. Zero pressure. No feature is gated behind payment.

━━━ OPEN STANDARD ━━━

DevDocs uses the Dash docset format — the same open format powering Dash on macOS, Zeal on Linux and Windows, and dozens of developer tools worldwide. Any Dash-compatible docset works out of the box.

━━━ BUILT FOR DEVELOPERS ━━━

No cookie banners. No "sign in to read". No JavaScript loading spinners. No ads between paragraphs. Just the documentation, instantly, every time.
