Calls that ring on a locked screen
An incoming call comes up like a phone call, even with the app closed. A browser tab has to be open to hear anything.

Get the Space app for architects
On iPhone, on Android, or in any browser. Same mobile number on every device — what you do on one shows up on the others.
Or skip the install — open Space in your browser.
Why the app
Three things a browser cannot do
Everything else — projects, chat, drawings, decisions — works the same in a browser.
Recording a site meeting
Start it and put the phone in your pocket. Lock the screen, take a call, run the battery flat — it picks up where it left off.
The camera, one tap from the work
Photograph what is in front of you and attach it to the task, the room or the message without leaving the screen.
What you need
An Indian mobile number — that is what you sign in with. No email, no invite code. iPhone or iPad, an Android phone on Android 8 or newer, or any current browser.
Joining a call without an account
Somebody sends you a call link — open it, type your name, you are in. No app and no account. The link stops working a few hours after the call, and whoever sent it can cancel it sooner.
