iceGear Instruments

iceGear is a one-man small company based in Japan that develops audio plug-ins (effects and synthesizers).


The App Store may display an app that should have been purchased as if it has not been purchased.

The App Store may not show that the app has been purchased on a different device than the device on which the app was purchased. (For example, when you purchase an app on an iPad and then install it on a Mac.)

However, as long as you are using the same Apple ID, you should be able to install it for free for the second and subsequent installations, even if it is on another device.

If you continue with the purchase process, the App Store should eventually confirm that you have made the purchase and you should be able to download the app for free, even if it appears as if it has not been purchased.

Similar App Store behavior may occur with apps from other developers.

Mention of this App Store behavior by other developers
Moog Music:
All of this suggests that this strange App Store behavior is only a display thing and has nothing to do with actual billing. Please note that there is no official announcement from Apple regarding this behavior.
If you have further questions or concerns, I encourage you to contact Apple Support.
