Upgrade Offer for App Store Customers

The upgrade to Kaleidoscope 3 is available for a one-time cost of $69.99 (69,99€), a massive discount compared to the full price of $149.99 (149,99€).

The App Store doesn’t offer upgrade pricing, so we cannot provide you with an upgrade on the App Store. But we still want you to be able to upgrade to Kaleidoscope 3 at the same price we offer our direct customers. That’s why we created this page.

In order to qualify for this special upgrade price, we need to confirm that you are a licensed user of Kaleidoscope 2. Use the box below to check the Kaleidoscope app from your computer. Once validated, you will automatically be forwarded to our store. There you can purchase the upgrade at the special price. You will then own a permanent license for Kaleidoscope 3.
