Unfortunately, we do not currently offer a team plan for the Estimator app. However, you can share your account with someone else by having them download the app on their device and log in using your phone number and password. Keep in mind they will have full access to your account with no way to limit their access.
You can use the app across different devices by downloading the app and using the same login credentials on each device. All your estimates will be synced and accessible from any device.
You can also login to www.simplywise.com on a computer so that you or your teammates can access your account there.
Please note that while estimates are synced across all devices, certain settings are not synchronized, including markup settings, and business information. These will need to be set up individually on each device.
