 ### New Device Support: Embed Fire
 This device shares similarities with the WonderMV but stands out with its larger 2.4" touchscreen.
 
+### Krux apps (Kapps)
+New tool for executing developer-signed utility apps that extend Krux functionality. Includes two initial Kapps: 
+- Nostr: Create or load your key using NIP-06 or NIP-19, and airgap-sign events
+- Steganography: Concel data within BMP image files
+
 ### New Device Support: WonderK PRO
 From the wonderful land of Korea, a new creation arrives: the WonderK PRO. Created by an entrepreneur who loves the Krux project, the WonderK follows in the footsteps of the WonderMV, but boasts a larger 2.8" display! Computer simulator for the WonderK device is also included.

+Run developer-signed Krux applications (Kapps) that are not suited to be part of the main firmware. Copy its `.mpy` file and corresponding signature to an SD card to load it onto the device. When executed, the Kapp is stored in the user's flash memory (just like custom settings) and this process modifies the last two words of the [Tamper Detection](tamper-detection.md#tamper-check-flash-hash-tc-flash-hash-a-tamper-detection-tool) (User's Region).

+For example, the **Nostr Kapp** allows converting a mnemonic into a Nostr `nsec` key and air-gapped event signing.
