Yes, you can use Paratext on multiple computers or devices! You can even use the same Paratext registration information on multiple devices.
To start working on a different device:
- Do a Send/Receive on the computer / device you are currently working on.
- Then, do a Send/Receive on the computer / device that you are going to start working on.
For example, if you are working on Device A and you want to switch to Device B:
- Do a Send/Receive on the Device A.
- Do a Send/Receive on Device B.
This will keep your project(s) synchronized across multiple devices. Just repeat this process anytime you want to switch devices.
