New in 2.0 — iPhone, iPad & Mac
Think in branches, not lines.
AsterBridge is a mind mapping app for iPhone, iPad and Mac. Capture an idea, branch it into related thoughts, and watch your thinking take shape — on an infinite canvas or as a clean outline.
Why AsterBridge
Built for the way you actually think.
Plan a launch, outline an essay, organize a trip, or just clear your head. AsterBridge gives you room to think visually and the polish to share what you make.
Infinite canvas
Pinch, pan and zoom. Your maps grow as your ideas do, with a mini-map, zoom to fit and alignment guides. Keep Tidy lays the map out for you as you add, move and delete ideas.
Fast to capture
Type a whole branch without leaving the keyboard: Return adds the next idea, and the keyboard bar adds children, indents and outdents.
Canvas or outline
The same map as a zoomable canvas or an editable outline. On iPad and Mac, use both side by side.
On every Apple device
Made for iPhone, iPad and Mac, and kept in sync through your own iCloud account. Start on the Mac, carry on on the train.
Map together
Invite people to view or edit a map through iCloud, and changes sync within moments. In a FaceTime call, map together live with SharePlay.
Private by design
No analytics, no ads, no tracking, and no third-party SDKs. Your maps are stored in your own iCloud account.
Features
Everything you need. Nothing you don’t.
The canvas and the outline, the nodes, the way you bring ideas in and share them, all native to iPhone, iPad and Mac.
