The Arduino App Lab is an integrated development environment (IDE) and simplifies prototyping. The new release 0.4.0 facilitates import/export functions, for example.

The App Lab was introduced together with the Arduino UNO Q. The UNO Q is the first model in the UNO family to be equipped with a processor from Qualcomm. Arduino was acquired by Qualcomm in October 2025.

The new version 0.4.0 of the Arduino App Lab brings a significant improvement in user-friendliness: thanks to a one-click import/export function that creates a complete project as an archive in standard ZIP format, users can share their creations more easily.

Secondly, the upgrade includes a new integrated firmware flasher. Arduino App Lab automatically detects whether the UNO Q has an outdated image and guides the user through the update directly in the app, without the need for CLI tools or terminal commands. However, the firmware flasher requires a whopping 10 GB of disk space for temporary storage on the host computer.

Thirdly, the new release offers the option of skipping the connection of the Arduino UNO Q to a WLAN network at the touch of a button. This is helpful for users who work offline or with low bandwidth.

The fourth new feature of the upgrade is enhanced syntax highlighting with support for web languages such as HTML, CSS and JavaScript and related web development languages, improving readability and reducing errors for users creating interfaces. (mk)
