Before you try Duo.

A work in progress.

Duo is a product by Tomeku. We offer paid early access to version 0.2.1, an unfinished development preview. Features and compatibility may change. Purchase only if the current preview meets your needs, not in expectation of future features.

The preview has limits.

The interactive website demo is simulated. The Mac app includes five fold scenes, ten optional sounds, and license activation for up to two Macs. The illustrated preview is available without a key; live desktop effects require an activated license. A scene marketplace, scene imports, and automatic updates are not available.

Before purchasing.

A license is a one-time purchase at $1.99 USD or €1.99 EUR for up to two Macs, with no subscription. Polar selects the currency based on location and shows the final total and applicable tax treatment before payment. The DMG is unsigned and contains an ad-hoc-signed app; neither is notarized. macOS may block it and require an app-specific approval. Please do not buy this preview if you need a signed, notarized release today.

Compatibility and delivery.

Apple silicon and macOS 14 or later are required. Physical lid response needs a compatible MacBook sensor and built-in display; support varies by model and macOS version. The free illustrated preview does not verify physical sensor support. The app downloads from this website; Polar provides the license through its customer portal and sends the order confirmation. Initial activation requires internet access. A validated license can work offline for up to seven days.

Orders and help.

Polar is the merchant of record and handles payment under its buyer terms. For delivery, billing, or refund requests, email billing@igotduo.com with your order number. Do not send card details or your full license key. This preview notice does not limit any mandatory consumer rights.

Independent, and made for Mac.

Duo is not affiliated with or endorsed by Apple. Required third-party notices are included with the app and are accessible from About.
