Signing in on multiple devices

Most people end up signed in to Cradle on more than one device, the work laptop and the mobile is the common pair. Cradle allows one active desktop session at a time plus the mobile app. There are a couple of behaviours worth knowing about so you don't get caught out.

What works the way you'd expect

You can be signed in to one Cradle desktop session and the Cradle mobile app at the same time on the same account.
Your call log, contacts, voicemail, and call recordings sync across every device you're signed in on.
Outbound calls work from either device. Pick up the one in front of you.
The mobile app rings when you have an inbound call, the same as the desktop, provided your presence allows it.

Presence is one state per person, not per device

There's only one presence for your Cradle account. If you're Available on your desktop, you're Available on your mobile too. Two devices don't make you "more available" or send two rings to the same caller.

The desktop is the source of truth for presence, mobile follows along. Read How does presence work? for the full story; the short version is:

Changes you make on the desktop ripple to your mobile.
The mobile app won't automatically set you to Idle or Offline, that's a desktop-side behaviour.
On a call is set automatically on whichever device you're calling from.

If you want to be reachable while you're away from your desk, leave the desktop signed in and Available, and have the mobile app installed and signed in too. Calls will reach you on either device.

Only one desktop at a time

You can only have one active Cradle desktop session at a time. If you sign in on a second computer, the desktop session on the first machine quits itself after a short notification. This prevents the two desktops from racing to answer the same inbound call.

If you switch between machines mid-day (work laptop in the morning, home computer in the afternoon), this means you re-sign-in each time you switch. Your work isn't lost; the call log, contacts and voicemails are all in Cradle, not on the machine. The mobile app is separate and stays signed in across the switch.

Signing in on a second machine

You don't need to sign out of your existing computer before signing in on a new one. Open Cradle on the new machine, sign in with Log in with Google or Log in with Microsoft as you would the first time, and you're in.

The previous desktop session will quit itself automatically. Cradle allows one active desktop session at a time. When you sign in on a second computer, the Cradle desktop app on the first machine receives a notification that you've signed in elsewhere and then exits. This is by design, it prevents two desktops from racing to answer the same call. The mobile app is separate and stays signed in regardless.

If your colleague says "Cradle just told me it was being signed out somewhere else", that's why; somebody (probably them, on another computer) just signed in.

If you've finished with the old machine for good, the cleanest thing to do is to sign out from it intentionally before walking away. See Signing out and switching accounts.

Mobile signed in alongside desktop

Mobile and desktop are designed to coexist on the same account. Signing in to the mobile app doesn't sign out your desktop, and vice versa.

Install the Cradle iOS app or Cradle Android app from the store.
Sign in with the same Google or Microsoft work account you use on the desktop.
Presence stays on whatever the desktop is set to, see "Presence is one state per person" above.

If you only use Cradle on mobile (no desktop signed in), your mobile becomes the authoritative device. Read the mobile section in How does presence work? for the full picture.

What you should see

Each device shows your name, presence, and call log identically.
The team screen shows you once, with one presence dot, regardless of how many devices you're signed in on.
An inbound call lights up every device that's eligible to ring. Picking up on one ends the ring on the others.

If something looks off

Cradle on my old machine just told me it was being signed out somewhere else. Somebody (probably you, on another computer) just signed in on a second machine. The older desktop session quits itself; this is by design.
A new sign-in killed my old session. Same cause as above. Sign in again on the device you actually want to use. See Your session has expired for the related sign-in messages.
My mobile isn't ringing even though my desktop is. Check the phone's OS-level Do Not Disturb or Focus mode. The phone OS can decline a Cradle call before the app gets a chance to ring, and that's separate from Cradle presence. See Why am I not receiving calls?.
