What each app does
Stereogram Go captures the data at the outcrop; Stereogram Pro is where you analyse and publish it. They are built to be used together.
Free beta Stereogram Pro is free to use while it is in beta. Subscriptions start . Until then there is nothing to pay and no card on file.
Stereogram Go is coming soon and is not yet on the App Store. A Stereogram Pro subscription buys the desk side today; Go is free and included when it lands.
