Knogra on Your Phone: A Companion Viewer for the Graphs You Build at Your Desk

Fri Oct 23 2026

A knowledge graph is built at a desk. Reviewing it is a different activity, and it happens in different places: the train, the queue, the ten minutes before a meeting. Those minutes have a phone in them and no computer. Knogra now has a page for them.

What it does

Open a graph and you are on a map, the one the Helicopter view draws: one concept at the centre, its neighbours around it, every connection in the same direction it has on the desktop. Double-tap a neighbour and the map re-centres on it, with the same animation as on the desktop, so what you came from is behind you. Tap a neighbour once for a closer look at it. Back and Home are on the bar at the bottom.

Swipe left for the notes of the concept you are on, right for the quiz, which hides a share of the graph’s concepts and asks you to name them as you travel.

Nothing has to be set up. Every graph has a map, and the map on the phone is the map you already know.

The phone viewer showing the map of Calculus: the focus in the centre with its equation, nine neighbours around it such as The Limit, Differentiation, Integration and Infinitesimals, each with its own formula, arrows from the focus to each, and a bar at the bottom with Quiz, Back, Home and Notes.

The same map during a quiz: the focus and two of its neighbours are blank boxes, a counter at the top reads 59 left of 59, and the bar now has Correct, Wrong, Back and Home.

A companion, not a second Knogra

The phone viewer does not edit, and this is by design rather than by omission. Building a graph needs a big screen: you arrange a dozen concepts to make a point about them, place images and equations, keep several scenes in view while you decide where a new idea belongs. None of that fits on a phone, and a phone version that pretended otherwise would be a worse editor with a smaller canvas. So the desktop is where the graph is made, and the phone is where you travel it, read it and test yourself on it. Nothing you do on the phone changes the graph.

Getting a graph onto the phone

From the library on knogra.io: every graph has a View button on a phone. Tap it and the graph is on your phone.

Your own graph: export it from the desktop app as you normally do, and make sure the file is somewhere your phone can see, such as iCloud Drive, OneDrive or Google Drive. On the phone, open the viewer’s Library page and tap Open a file. The file picker shows every cloud your phone knows about, so it is one mechanism for all of them. A note for Mac users: the Documents folder is in iCloud Drive by default, the Downloads folder is not, so save the export to Documents or move it there once.

The phone holds one graph at a time; installing another replaces it, and the library is always one tap away.

Make it an app

Safari forgets a site’s data after a week without a visit. An icon on the home screen does not, and it opens the viewer without the browser’s bars, which also makes landscape usable. Three steps, once:

  1. Open the viewer in Safari, at app.knogra.io/view.html or through a View button in the library.
  2. Tap the Share button, then Add to Home Screen, then Add.
  3. Open it from the icon. It starts on its Library page, because an app on the home screen has its own storage, separate from Safari’s. Pick your graph there, or open your file, and it stays.

From then on the icon is the viewer, and the graph is there when you open it.

That is all of it. The desktop is where the graph is made; the phone is where it is kept in mind.
