Once you've signed up from one device you can then login to you account on any number of other devices.
When logging in on a different device, you'll be asked if you want to:
- sync with the new device.
- continue in a "read-only" mode
By selecting the second option, you will be able to access all features but changes won't be synced directly to the second device. Instead they will be synced with your contacts accounts through your 'main device'.
On laptops, desktops and tablets we recommend logging in to the Covve webapp (https://app.covve.com) which will make good use of the larger screen size while on other mobile phones you simply install the app and login to your account.
