You can check the current best-value region on AppPriceHub's real-time pricing page for the latest rates.

Create an Apple ID registered in your target low-price region, switch to that account in the App Store, top up with a regional gift card, and complete the subscription. A Duet Display subscription unlocks premium features including Duet Air remote desktop access, and cross-region purchases activate normally on both Mac and iOS devices. When it's time to renew, switch back to the subscribing Apple ID and ensure your balance is sufficient — this has no impact on your connected devices or usage history.

A Duet Display subscription primarily unlocks remote access and advanced display features, with no functional limitations for cross-region use. A few things to keep in mind: gift card exchange rate fluctuations can affect your actual cost; app updates may roll out slightly later in some lower-priced regions; and Duet Air remote access depends on your network environment rather than your subscription region. Overall, the cross-region risk is low. Given the wide price range (¥9.43–¥740.48), the savings potential in lower-priced regions is substantial.

Duet Display starts at ¥9.43/year with an average price of ¥221.6/year, offering iPad/iPhone as a secondary display along with remote desktop access. Comparable tools include Luna Display and Sidecar (a free built-in macOS feature), each with different trade-offs. Sidecar requires no subscription but has limited functionality. Duet Display stands out in remote access scenarios, and pairing it with a low-price region strategy can significantly reduce your annual cost.
