nope, 2.1.1 ios is only compatible with 2.1.1 PC version right now
Per the FAQ page...
Can the IOS or Android versions of Artemis work with the Windows version?
They are designed to do so, yes. However, the IOS and Android versions that are available in the mobile stores often have an earlier version number than the Windows version. If the two programs have different version numbers, they usually don’t work well together.
I build the latest Windows version first, and then contract out the IOS and Android versions, so it can take a while to bring them to the same version.
So, I often provide an extra update version on the downloads page of this website. The Windows update file will match the mobile device version, so you can (if you wish) “roll back” your Windows version so it matches the mobile version.
