Mobile and tablet
Clusters works in a mobile browser, installs as a PWA, and ships as iOS and Android apps. On touch devices the canvas gets pinch-zoom and long-press menus, a bottom navigation bar replaces the sidebar, and a focus view strips everything back to the board. Tablets with a stylus get full drawing support.
Three ways to run it on a phone or tablet: the mobile browser, an installed PWA, or the native iOS and Android apps. They are the same app.
Touch on the canvas
| Gesture | Does |
|---|---|
| One finger drag | Pan |
| Pinch | Zoom |
| Tap | Select |
| Long press | Context menu |
| Double tap | Add menu at that point |
Drawing gestures are guarded so the canvas cannot start panning halfway through a stroke — the failure that makes drawing on touch unusable.
Layout differences
Bottom navigation replaces the sidebar — Home, the current board, Messages, and more.
A drawer holds navigation that does not fit.
The add sheet replaces the tool rail's + menu with a full-width sheet, sized for thumbs.
Focus view — touch only — strips everything back to the board itself, for reviewing on a phone without chrome in the way.
Tablets
Tablets get closer to the desktop layout — the rail rather than the sheet — plus stylus drawing. On iPad, drawing, annotating and reviewing all work properly; long document editing is still better on a laptop.
The Home graph renders its 2D fallback on most tablets, which has the same nodes and interactions.
Installing
As a PWA — "Add to Home Screen" from the browser. It runs standalone, without browser chrome.
Native apps for iOS and Android handle the status bar, keyboard behaviour, the splash screen, deep links, the Android back button, and the system share sheet — so exports land in Files or another app rather than a downloads folder.
Getting photos in from a phone
Three routes:
- Upload from the add sheet — the camera roll picker.
- Share sheet from Photos.
- Soleil Scout — text them, with no app at all. Note that Scout's phone line is not live yet.
What is worse on a small screen
Honestly: dense surfaces. Long documents, screenplay writing, big grid layouts and the 3D graph are all usable and all better on a large screen.
What is genuinely good on mobile is capture and review — getting photos in, and looking at a board someone sent you.
Frequently asked questions
Is there a real app?
Yes, for iOS and Android, with native handling of the status bar, keyboard, splash screen, deep links and the Android back button. It can also be installed from the browser as a PWA.
Can I draw on a tablet?
Yes, with a stylus or a finger. Drawing gestures are guarded so the canvas will not pan mid-stroke.
Is anything unavailable on mobile?
Nothing is removed, but dense surfaces like long documents and the 3D home graph are much better on a large screen. The graph falls back to 2D on tablets.
