App Dev for All Launches Knowledge to Go, Turning Android Phones into Offline Libraries for the World’s Unconnected Communities
Free, open-source app ports the celebrated Internet-in-a-Box project to Android, potentially reaching billions of devices
Belmont CA — App Dev for All (ADFA), a philanthropic venture dedicated to making software development accessible to all, today announced the release of Knowledge to Go (K2Go™), a free and open-source Android application that transforms virtually any Android phone (including older 32-bit devices) into an offline content server capable of sharing educational, medical, and technical resources with anyone nearby over local Wi-Fi.
K2Go began as a port of the widely respected Internet-in-a-Box (IIAB) project, which has for over a decade delivered offline libraries of Wikipedia, Khan Academy, OpenStreetMap, medical references, and other resources to schools, clinics, and communities across more than 100 countries. Where IIAB requires a Raspberry Pi or Linux computer, K2Go requires only an Android phone, a device that billions of people worldwide already own.
“There are tens of millions of Raspberry Pis in the world and billions of Android phones,” said David Schachter ADFA’s founder. “K2Go means that anyone who already has an Android phone can become a knowledge hub for their community without needing additional hardware.”
K2Go was developed with foundational collaboration from Adam Holt and the IIAB community. According to Schachter, “Internet-in-a-Box has always been about getting the world’s best free knowledge to anyone, anywhere. Knowledge to Go extends its reach into the billions of Android devices already in people’s hands.”
Rooted in a Broader Mission
ADFA’s work on K2Go grew directly from its flagship product, Code on the Go (CoGo™), a full-strength Android IDE that allows people to learn, write, debug, and build real Kotlin and Java applications entirely on a phone, without internet access or a computer.
Says Schachter, “We built CoGo for people who want to build apps but don’t have computers or reliable internet access. We built K2Go to make CoGo and IIAB’s offline resources widely available on the most common computer in the world: Android phones.”
How It Works
Only one person, somewhere, needs internet access exactly once. They install K2Go on an Android phone, select content packs including Code on the Go and resources from the IIAB content ecosystem, and download them while online. From that point on, no other phone in the chain ever needs to connect to the internet.
That first phone can act as a local Wi-Fi server, letting nearby smartphones, tablets, and laptops access the content directly through a browser, with no internet connection of their own and no other software to install.
K2Go also goes a step further: its server and content packs can be cloned onto any other Android phone, completely offline. Each cloned phone becomes a full K2Go server in its own right, able to serve nearby devices and be cloned again by someone else.
The result is a chain that can spread from one single internet connection to any number of phones, with no device after the first ever needing internet access.
Availability
K2Go is available now as a free download. The app supports a broad range of Android devices, including older 32-bit and affordable low-end phones that are common around the world.
