Follow these steps to activate the pro features of Graphical Analysis on an iPad or iPhone using your school’s nine-character Graphical Analysis Pro license key. See, How do I distribute the Graphical Analysis Pro license key to my students?

Open a browser (Safari, Chrome, etc.) on your iPad or iPhone, and navigate to https://graphicalanalysis.app/auth/

Note: If you have a twelve-character activation code, you’ll need to first use it to obtain a license key. See How do I redeem a Vernier product license activation code? How do I extend an existing license?

Why is activating the Pro features on iPad/iPhone different than other platforms?
The method of activation used in other applications (including iPad/iPhone for version 6.0.0 and older) was determined by Apple to not comply with their in-app purchase requirements. In order to provide updates, we were required to change the way the Pro license was applied.
Will the license key I have used previously for iPad/iPhone (and/or other devices) still work with the updated app?
Yes. Older, valid license keys will work with this newer version of the app.
If I have multiple devices under the same Apple ID, can I apply the license key to just one device and have that apply to all devices using that same ID?
No. The license key needs to be applied to each device individually.
Is there a way that I can push out the license key to multiple iPad/iPhone devices?
Not at this time. We will look for ways to improve this process, but for now it is a manual process.
Will I have to reapply the license key when there is an update to the app?
No. Once you have completed the process for v6.2.0 (or newer), the license key will be remembered and applied as long as it is valid. However, updating from a Pro activated v6.0.0 (or older), will require you to activate the Pro features again when updating to v6.2.0 (or newer).
